The work is performed with a mouse and/or keyboard. 32 Operation 7 2.1 Using the mouse In addition to the typewriter–style keyboard, line editor and arrow keys, you can also use the mouse. Please note that a parallel mouse (”bus mouse”) needs its own slot in the PaDT and has to be configured. Die Installation einer Maus entnehmen Sie bitte den Unterlagen des Herstellers. Mouse functions with the software The left key is used to call and confirm a function. It is therefore equivalent to the <Return> key. The right key is used to cancel or break, and is equivalent to the <Esc> key. Pressing both keys at the same time is equivalent to the key combination <Ctrl>+<Return>. Warning: By select with the parameter /NOPLC the mouse is used at the interface COM1. The function<Ctrl>+<Return> (pressing both mouse keys at the same time) is not possible in this case. By Select without /NOPLC the mouse has to used at the interface COM2. 8 Operation 32 2.2 Using the keyboard 2.2.1 US/German keyboard The following key legends are different on the German and English keyboards: US / UK keyboard <Esc> <Ctrl> <Home> <End> <Prtsc> <PgUp> <PgDn> <Ins> <Del> 2.2.2 German keyboard <Eing Lösch> <Strg> <Pos1> <Ende> <Druck> <Bild > <Bild > <Einfg> <Lösch> oder <Entf> Keyboard sections The programming panel keyboard is divided into three different sections: Typewriter keyboard and control keys The typewriter keyboard is located in the middle (light keys) and is surroundet by darker control keys. Only the white keys cause a display of the imprinted symbol to appear on the screen when they are pressed. In the Dolog AKF Software, these are used to operate the line editor, the key macros and the reference characters (s. ”Special keys” Chapter 2.2.8) and to enter text. 32 Operation 9 Function keys These play a lesser role in pulldown menu, since all functions are selected with the mouse, reference characters or arrow keys. These keys are located above or alongside the typewriter keyboard (depending on the PaDT model) and are labeled <F1> ... <Fx>. Numerical pad The arrow keys and numerical pad are located to the right of the of the typewriter keyboard.You can toggle between the numerical pad and the cursor pad with the <NumLock> key. Of those in the numerical pad, the arrow keys are needed chiefly for the Dolog AKF Software. They are used among other things for selecting the various menu lines (see below). The numbers are used to call Graphics characters (e.g. in the title block): <Alt> + <number>. 10 Operation 32 2.2.3 Line editor, ”Line editor” The line editor helps you to input text and/or numbers and consists of combining the use of control keys and the typewriter keyboard. It places the following editor functions at your disposal: <Home> Cursor to the beginning of the input line <End> Cursor to the end of the input line < ³> Cursor to the right < ²> Cursor to the left <Return> End of input <backspace>, < ä> Delete character to the left <Del> Delete character at cursor <Ctrl>+<T> Delete input <Ctrl>+<R> Restore original text <Ins> Toggle between insert / overwrite (big Cursor)/ overwrite (little Cursor) <Esc> input eliminate Using the <Esc>-key interrupts input and the previous text ist restored. You can use the key macros to insert stored texts (e.g. symbols, comments, hardware adresses, File names and parts of them.). 32 Operation 11 2.2.4 Screen copy, ”Screensave” This function is used to copy the complete current screen contents into a file. No printer need be connected. The file is stored in the directory of the current station in IBM-ASCII format. The copy (file) thus generated can then be edited using a text editor. Step Simultaneously press the <Alt>+<F2> keys to generate a screen copy. The first screen is saved under the name ”BILD0.BLD”. Screen 2 is called ”BILD1.BLD” etc. Note If you leave Dolog AKF and start over, screen numbering begins again at Bild0.bld. This means that copies created earlier with the same name will be overwritten. 12 Operation 32 2.2.5 Key input memory, ”Learning” This function can combine up to 40 procedures (key inputs) Step 1 Simultaneously press the <Alt>+<F8> keys to activate the function. Step 2 Press the key combination to which input sequences are to be assigned. You can assign <Alt>+<0>, <Alt>+<1> etc. up to <Alt>+<9>. ”Learning”appears in the status line. Step 3 Choose the required menus with the reference characters (up to 40 entries per assigned key). Step 4 Press <Alt>+<F8> to end learning. ”Learning” disappears from the status line. Step 5 For storing you terminate Dolog AKF. Step 6 Start Dolog AKF again. Step 7 Press<Alt>+<0>, <Alt>+<1> etc. bis <Alt>+<9> the procedures you have saved. to run Note The menus should be selected with reference characters in order to make the learned functions independent of the current menu bar position. 32 Operation 13 2.2.6 Key text buffer, ”Key macros” This simplifies the editing of symbols, comments, hardware addresses etc. Frequently used absolute or symbolic addresses can be stored as text. Proceed as follows. Step 1 Press <Alt>+<F9> to activate the function. Step 2 Press the key combination to which text is to be assigned. You can assign <Alt>+<A>, <Alt>+<B> etc. up to <Alt>+<Z>. Step 3 Enter up to 19 characters of text. Step 4 Press <Return> to save. Step 5 Press <Alt>+<A>, <Alt>+<B> etc. up to <Alt>+<Z> to call the stored text to the cursor position. At step 4 you can break off input by pressing <Esc>. Example: the text Valve was stored. It was inserted as part of symbol/comment inputs (Valve 1 on, Valve 2 off, Valve 1 half, ...). 2.2.7 Auto Repeat Function Most of the keys on a PaDT are equipped with the auto repeat function: When you press down a key the symbol on the key itself is displayed on the screen or a corresponding function is executed. If the key is held down for longer than about 0.5 s, the key function is repeated up to 10 times a second until the key is released. Therefore take care not to use this key function unintentionally. 14 Operation 32 2.2.8 Special keys The following keys are of particular importance for controlling menus: Reference characters Reference characters are used to select and execute a menu directly from the typewriter keyboard. You access the corresponding function by inputting the specially marked capital letter. The highlighting colors may be adjusted in the ”Setup” und ”Color” sections. <Ctrl>+reference character Within an editor, the individual functions can be called with<Ctrl>+reference character, without having to open the menu. Arrow keys With the arrow keys (movement keys, Cursor keys, direction keys) <°>, <±>, <³>, <²> you can select individual menu lines. The keywords are selected using the latter in the helptext. (When editing) A key depression corresponds to: <± > one line down (in the same column) <°> one line up (in the same column) <³> one column to the right (in the same line) <²> one column to the left (in the same line) Make sure you have switched the <NumLock> key off, so that the key respond. When editing a block you can move the cursor with the mouse as much as you like without restriction. <Return>-key, <Ctrl>+<Return> The <Return>-key (also <Enter>, <Übernahme>, <Cr>) is used to call certain functions or to accept (translate) (beenden). You can also toggle with it. Call within the help function in order to call the help texts for the selected keyword. in the pulldown menus in order to call the selected menu line (menu function. in ”Edit” (Blocks, Equipmentlist etc.): mit <Ctrl.>+<Return>calls the editing function windows. Exit, Accept 32 Operation 15 when editing a network and when making entries with the line editor, press the <Return>-key to accept the parameter, hardwareadresse or comment etc. you have just entered. ”Toggle” Many menu functions provide direct selection of prepared settings. Thus, for example, you can switch between ”off” and ”on” or ”IL”, ”LD”, ”FBD” directly (”toggling”), without having to enter text. You can toggle in the following manner: 1 type the referenced character 2 Go to the line using the arrow keys and toggle by pressing <Return>.The <Return> key is equivalent to the left button on the mouse. <Esc>-key Using the <Esc>-key you can interrupt, i.e. break off any function ore input within the Dolog AKF Software. The <Esc> key is equivalent to the right mouse button Caution If you are at operating system level, you can interrupt only with <Ctrl>+<C>. Dies trifft bei den Funktionen im Menü ”Sonder” zu. <Ins> key In the line editor, in the case of comments and headers, you can use this key to toggle between the ”Insert” and ”Overwrite” text input modes. in the block edtor, ”insert” has the effect of automatically performing a vertical spread in the network. Table of Important Keys At this stage it is not appropriate to list the most important special keys and key combinations. The same key combinations can perform different functions. When questions arise, please consult the index, where a key assignment table can be found. In addition, the explanation of each menu describes the available keys and their meanings. 16 Operation 32 Chapter 3 Programming This chapter describes programming with the DOLOG AKF software for A120. The chapter is intended as a reference for the person configuring the system. Its structure follows the menu structure. Menu points that occur more than once are only discussed once (the first time). The index contains the page numbers for the description of menu points that occur more than once. 33 Programming 17 3.1 General The individual menu points are described in the following order: Dolog AKF main menu Chapter 3.2 Edit Chapter 3.3 Load Chapter 3.4 Online Chapter 3.5 Print Chapter 3.6 Special Chapter 3.7 Setup Chapter 3.8 First you will be shown to select the menu line required (the ”path” from the main menu). The functions which you can execute at this point (programming, documentation, backup etc.) are then described. This symbol shows how you can select the described functions. The steps are always given starting from the main menu. e.g.: - ”Edit”, ”Equipment List”, ”Controller”, ”Marker Bits” means: Select the ”Edit” menu, Press Return to confirm the ”Equipment list” line, Select ”Controller” and confirm by pressing Return, ”Marker Bits” is the function which is now described. Note Some characters are written as capitals in the following description. They denote reference characters: e.g. SeTup 18 Programming 33 3.2 Dolog AKF main menu Status line, in this case the path of the current system/ station; depending whether installed on Ser. No. of the disketA: tes as B: shown on C: slipcase D: or E: 33 Ser. No. of your software package (in accordance with software license agreement) Version No. of the present software Pulldown menus can be selected with reference characters, arrow keys + Return, or mouse Programming 19 3.2.1 Status line The bottom line of the display is known as the status line. The 78 characters of the status line are divided up as follows: 12345678901234567890123456789012345678901234567890123456789012345678901234567 8 1 32 50 65 3.2.2 - 30 48 64 78 complete path of system and station name message: LEARN Dolog AKF Status: FORCE active PLC scan status: PLC stopped / PLC active Pulldown menus Individual menu lines can be selected and called with reference characters, arrow keys and <Return>, or the mouse (refer to chapter on ”Operation”). 20 Programming 33 3.2.3 Help function Help texts describe a function. They tell you what can be carrid out with the currently selected menu line or the current window. Help texts are also available for the higher menus. The <F10> key is always used to display the help text belonging to a menu line selected from the pulldown menu. This text may contain things known as keywords. These are terms and expressions that have a further explanatory help text attached to them. Use the arrow keys to select them and press <Return> to call them. This makes the help texts easy to follow. The texts are generally reminders for DOLOG AKF beginners. Keywords are highlighted in color. <Alt>+<F10> takes you back to the help text selected previously. Press <F10> again, which brings you to ”Overview Help Texts”. This shows you the keywords you can select, without menu lines of their own. You may call references for any keyword in the index (index for help texts). The bottom edge of every help window contains a line in which the available functions are listed: <°>, < ± >, <²>, <³> Select keywords <Return> Call of helptext to the keyword <Esc> Abort and exit the help windows <F10> <Alt> + <F10> <PgUp>, <PgDn> 33 Overview helptext The helptext befor will called backword, forword scroll inside the helptext Programming 21 3.3 Edit The funktions into the Pulldown–menu ”Edit” are used for the configuration of the User programs. You can select and call the following menu lines: Edit Load Online Print Special Setup Help=F10 Overview Blocks Symbols and Comments Equipment list Title Block Replace Signals Compile Blocks Compile Data Blocks Caution The system / station set under ”Setup”, ”system”, ”PLC station” is processed. Enter the equipment list before the blocks. If you want to carry out symbolic programming, enter the data block under ”Symbols and Comments”. 22 Programming 33 3.3.1 Overview - ”Edit”, ”Overview” This function provides you with a graphical program run overview in a tree structure. This overview shows you how the complete program is structured, i.e. where and how often each block is called. This function enables you to shift the image, select with the cursor (with the possibility of switching to edit mode) and search for a block. The overview is generated on the basis of the OB1. The display is sorted by networks. If several blocks are called in a network it may be that they do not appear in the right order in this display. Figure 1 BScreen output for a program overview 33 Programming 23 After selecting <Ctrl>+<Return> you can select further special functions via a pulldown window: Structure Edit Block Scroll Forward Scroll Backward Search Block Terminate Outside the pulldown menu the functions can be called using <Ctrl>+<reference character>. In addition, the following special keys are available: <Esc> Abort < ±> Use cursor to move one element deeper <°> Use cursor to move one element higher <³> Use cursor to move right <²> Use cursor to move left <PgDn> Next page <PgUp> Previous page Edit Block - ”Edit”, ”Overview”, ”Edit Block” First of all select the block to be modified with the arrow keys or the search run. Press <Return> to switch to Edit mode. The block on which the cursor was located can be edited. Caution After exiting from Editing mode no new program overview is created. If you deleted or inserted block calls during editing, these will not be displayed on the screen. 24 Programming 33 Page up / page down - ”Edit”, ”Overview”, ”Page up” - ”Edit”, ”Overview”, ”Page down” This enables you to scroll to the previous or next page in the Overview. <PgUp> is equivalent to Scroll backwards, <PgDn> is equivalent to Scroll Forward. Search block - ”Edit”, ”Overview”, ”Search Block” Here you can search for blocks within the Overview. The search direction can be specified by prefixing a ”+” or ”–”. The block name must be declared in full. Exit overview - ”Edit”, ”Overview”, ”Exit” This terminates the Overview function. You can also exit from the overview with the <Esc> key. 33 Programming 25 3.3.2 Blocks - ”Edit”, ”Blocks” This pulldown menu is used to generate the actual program. You can use the editors to programindividual blocks in the display format you have selected. First of all the blocks editors will be described, then the individual menu lines will be explained. The following functions are available in this pulldown menu: Edit Blocks Start Entry Block Number: Network Number: Block: Input Mode: Adressing: Output Monitoring 1 1 PB1 FBD ABS off Block Editors The available Block Editors are the IL-, LD- and FBD-Editor (depending on the ”Input mode”). The blocks OB, PB can be entered and reproduced in the special language DOLOG AKF in an instruction list (IL), ladder diagram (LD) and function block diagram (FBD). The network 1 of an FB can only be entered and reproduced in IL. The networks shown below (2 – 999) can be ebtered and reproduced in IL, LD and FBD. During editing of the user program (after ”Start Entry”) you can change the type of presentation under ”PrEsetting” (”toggle”). Networks are presented on screen in the display format selected, regardless of wich display format they were programmed in. 26 Programming 33 There are exceptions. For example, if a network is programmed in IL and is then to be displayed in FBD, this cannot be done since it contains commands (LD, T, jumps) which cannot be shown in FBD. Also if the screen is not wide enough because of the number of elements to be displayed (LD cannot display an ”AND” with more than 7 inouts, an ”OR” with more than 16 inputs or several FBD elements in a parallel path). Exceptional cases such as these are always presented in IL, regardless of the display format selected. During editing and reproduction of a network the type of addressing can be modified as you choose. After input, the program is automatically examined for syntactical accuracy. Start Entry - ”Edit”, ”Blocks”, ”Start Entry” - ”Edit”, ”Overview”, select block, <Ctrl>+<Return>, ”Edit Block” Note Only once the other settings in the pulldown menu have been defined is editing started here with <Return> or the reference character. If the block set is not available it will be created. To call the editing pulldown menu (”Edit network”) press <Ctrl>+<Return>. In addition you can up a relevant help text at any step using <F10>. You can exit from the editing procedure at any time with the <Esc>. All the data entered until that time, apart from the comments and symbols of signals, will however be lost. 33 Programming 27 Editing in different display formats You can program in three display formats. It is possible to switch between the individual technical languages at any time. The various Editors will now be explained. Certain menu lines or functions are present at several locations in the editor, or are the same in several editors, for example the ”Edit Network” menu. These positions are only described the first time they occur. The keyword register provides further guidance. Instruction list IL IL Editor - ”Edit”, ”Blocks”, ”Start Entry”, <Ctrl>+<Return> - ”Edit”, ”Overview”, select block, <Ctrl>+<Return>, ”Edit Block”,.. Note If you select an existing block in the required display format, you can then edit it. After pressing <Ctrl>+<Return> you switch to the menu ”Edit network”, the structure of which is the same for all display formats. The common functions are described here in IL. 28 Programming 33 You are now in the IL editor, which is described below. You can edit in IL in the pulldown menu ”Edit network” using the reference characters, by selecting the menu line with arrow keys and calling with <Return> or using the mouse. Insert Erase Copy Modify Scroll forwards Scroll backwards Terminate (save) Break Search Signal Search Network Exchange online Dynamic Status Display If you press the <Return> key you can also select the functions listed above via the menu line of the pulldown menu ”Edit network” which is displayed in the bottom right hand corner of the screen. During network creation in IL editing takes place line by line and in tabular form. In other words, certain tab positions are reserved for the IL operations (operations), the operands and the IL Line comments. These can be reached by pressing the <Tab> key or the Arrow keys. For OBs, PBs and FBs each Il line can be given its own comment (max. 32 characters). Within the input fields the line editor (typewriter keyboard) can be used with all keys (including e.g. <Backspace>). 33 Programming 29 Edit IL, LD, FBD / Network insert - ”Edit”, ”Blocks”, ”Start Entry”, present block, <Ctrl>+<Return>, ”Insert” - ”Edit”, ”Overview”, select block, <Ctrl>+<Return>, ”Edit Block”,.. With this function ”insert” in the pulldown menu ”Edit network” you can insert a new empty network before the network displayed. Exception: Insertion of an FB in front of the first network is not permitted. After inserting the new, initially empty network you will be in the correction mode of the Editor. Edit IL, LD, FBD / Delete network - ”Edit”, ”Blocks”, ”Start Entry”, present block, <Ctrl>+<Return>, ”Delete” - ”Edit”, ”Overview”, select block, <Ctrl>+<Return>, ”Edit Block”,.. With the ”Delete” function from the ”Edit network” pulldown menu, you can delete the indicated network. The last remaining network of a block or the block end network cannnot be deleted using this function. To delete the entrie block use ”Special Delete”. 30 Programming 33 Edit IL, LD, FBD / Copy Network - ”Edit”, ”Blocks”, ”Start Entry”, present block, <Ctrl>+<Return>, ”Copy” - ”Edit”, ”Overview”, select block, <Ctrl>+<Return>, ”Edit Block”,.. With this function ”Copy” in the pulldown menu ”Edit network” you can insert (copy) a network created preciously elsewhere before the network displayed. Exception: Insertion of an FB in front of the first network is not permitted. After selecting the function a window is displayed in which you enter the network to be copied. It is then copied in front of the current network.

This function or <Del> is used to delete elements from a network. Deleting an element: The cursor has to be in the upper left corner of the block. Deleting several continuous elements: The cursor must be at the start of the element sequence to be deleted. Deleting inputs: The cursor must be on the signal to which an input has been assigned. The network is optimised when this function is executed. 64 Programming 33 Block number - ”Edit”, ”Blocks”, ”Block number” - ”Load”, ”Exchange Online”, ”Block number” - ”Online”, ”dynamic state display”, ”Current display”, ”Block number” Enter the number of the block which you want to edit (1-999) here. After pressing the <Return> key you can enter or change the number using the line editor (typewriter keyboard). Note For OB block number must be 1! Block type - ”Edit”, ”Blocks”, ”block type” - ”Load”, ”Exchange Online”, ”block type” - ”Online”, ”dynamic state display”, ”Current display”, ”block type” The type of block to be edited is entered here (organization block OB, program block PB, function block FB). Note 34 Exchange Online: for OB block number must be 1! Programming 65 Organization block OB1 The organization block contains the information content of the whole user program. The OB is processed by cyclical scanning. Each scan starts by processing network 001 and ends when the last network present in the OB is processed. PB calls, FB calls and possibly user programs exist in networks with consecutive numbering, starting with network 001. Each network may contain only one PB or FB call (with the exception of IL). It calls conditional or unconditional PBs, FBs and SFBs. It can also contain program parts in IL, LD or FBD. Program block PB A PB consists of a sequence of networks, consecutively numbered starting with network 001. It can call conditional or unconditional PBs, FBs und SFBs. The same PB can be called several times. It contains program parts in IL, LD or FBD. In OB (or another PB), a block that is to be called is displayed as a square (in LD/FBD) in the network. The PB number is above the square. In the case of conditional PB calls the signal address of the condition is immediately to the left of the square. A PB that is not called from any place is never processed. 66 Programming 34 Conversion of a program block into a function block: Program blocks which have been tested and founded to be suitable by users can easily be converted into function blocks. To do this, proceed as follows: Step 1 Under ”Edit”, ”Blocks” here set the ”Input mode” ”IL” for instruction list. Step 2 Also set the desired program block here and choose the network. Step 3 Insert a further network (dummy network)in front of the first network and save the program block on the hard disk. Step 4 Copy this program block within your station using ”Special”, ”Copy” to form a new function block (the source block is the PB, the destination block is the new FB). Delete the old program block if necessary. Step 5 Under ”Edit”, ”Blocks”, ”Start Entry” call the new function block and select network 1. This network is still empty. Simply enter the new function block name (overwrite NW end). If necessary you can still edit the new function block by inserting formal operands. Note The ”key macros” function is useful for inputting formal operands (cf. Chapter 2.2.6). Step 6 Save the new function block. Don’t forget to then delete the appropriate program block calls within your user program and to program new function block calls. 34 Programming 67 Function block (FB) 999 user function blocks can be parameterized (named FB1 – FB999). The FB contains a part of a user program in instruction list, ladder diagram, function block diagram. Calling an FB ensures that the FB is then processed exactly to the runtime when the appropriate call is triggered in the user program. This enables you to optise the program yourself, thereby achieving shorter scan times. For the processing of the block, the formal operands of the FB are replaced with the declared actual operands. Formal operands are a maximum of 6 character long. The first character is a letter, the rest may be any characters. An FB which is not called from any point will not be processed. Structure The FB consists of the declaration part (network 001) and the instruction part (following networks). Declaration part In the declaration part is the name of the FB and the list of the formal operands, stating the type. Table 1 Example of the declaration part of an FB Formal operand Name: EXAMP1 IDT: OP1 IDT: OP2 IDT: OP3 IDT: OFF : *** 68 Type Possibilities (E/Ex/A/Ax/M/Mx/SM/SMx/T/Z/TN/B2/B8/B16/ANZ) (E/Ex/A/Ax/M/Mx/SM/SMx/T/Z/TN/B2/B8/B16/ANZ) (E/Ex/A/Ax/M/Mx/SM/SMx/T/Z/TN/B2/B8/B16/ANZ) (E/Ex/A/Ax/M/Mx/SM/SMx/T/Z/TN/B2/B8/B16/ANZ) Programming Type (I/O) E (I/O) E (I/O) E (I/O) A I I I O 34 The series (E/Ex/A/Ax/M/Mx/SM/SMx/T/Z/NODE/B2/B8/B16/ANZ) (I/O) provides information on the possible type statement. The meanings are as follows: E : input Ex : input (x = B, W, D: byte, word, double word) A : output Ax : output (x = B, W, D: byte, word, double word) M : marker (as bit) Mx : marker (x = B, W, D: byte, word, double word) SM : system marker (as bit) SMx : system marker (x = B, W, D: byte, word, double word) T : Timers Z : Counters TN : Nodes Bx : Bit string ANZ : Number I O : : The signal is an input parameter of the block The signal is an output parameter of the block. The appropriate representative must be specified from each of these two groups. A declaration from the group (I/O) is used to state whether the parameter is to be displayed in ther graphical display as an input an the left edge of the block or as an output on the right edge of the block. The declaration part ends with ”***”, Network end. The formal operand name can be changed at any time, but the block calls must be reprogrammed whenever changes are made. Instruction part The instruction part makes the algorithmic correlations between the formal operands of the declaration part (in IL/LD/FBD). In the instruction part the formal operands must be marked with an ”=” sign. Where appropriate, to the right of the instruction list is a number stating the nesting depth of the line in question. The instruction list always ends with ”***”, the instruction part with ”:BE” (Block end). 34 Programming 69 The following figures show the instruction part of the above function block ”EXAMP1” in IL, LD and FBD. IL Statement of nesting depth LD FBD call * Conditional call of a function block in ladder diagram or function block diagra * = condition instruction Instead of the question marks operands which are still relevant (M1.1, A2.4 ...) are to be input. An FB may be called from another FB or a PB. 70 Programming 34 The FB is shown as a square in the network (in LD/FBD). In the square, its description is once again displayed, in short form. On the left of the square is the imput formal operands and to the left of the square the actual operands, and possibly a further condition. On the right of the square is the output formal operands and to the right of the square the actual operands. In IL the block is called using the operand BA or BAB. Conditional call of a function block in instruction list. Actual operands (M1.1, A2.4, ...) are to be input in place of the question marks. The first line (condition) is to be created manually and linked logically. If formal operands are edited, deleted or inserted during editing of the declaration part if a function block, all the function block calls must be re–parameterized. The points in the user program at which the function block calls of the FB in question are located can be established using the global cross–reference list. It is also possible to call a function block from the instruction part of another function block (nesting). The function block called may contain its formal operand as an actual operand in the instruction part of the calling FBs. Thus for the runtime of the user program actual operands can be forwarded down to the deepest nesting level (10). Program blocks tried and tested by users can easily be converted into function blocks FB1...FB999 (see PB). 34 Programming 71 Network number - ”Edit”, ”Blocks”, ”Network number” - ”Online”, ”dynamic state display”, ”continuous display”, ”Network number” Here set the network (1 to 999) of the block which you want to edit after ”Start Entry”. After pressing the <Return> key you can enter or change the number with the line editor (typewriter keyboard). Input mode (Display Formats ILs, KOP, FUP) - ”Edit”, ”Blocks”, ”Input mode” - ”Edit”, ”Blocks”, ”Start Entry”, <Ctrl>+<Return>, ”Dyn. status display”, <Ctrl>+<Return>, ”Preset”, ”Input mode” - ”Online”, ”Dyn. status display”, ”Current display”, ”Start Entry”, <Ctrl>+<Return>, ”Preset”, ”Output mode” - ”Online”, ”Dyn. status display”, ”Triggered display”, ”Start Entry”, <Ctrl>+<Return>, ”Preset”, ”Output mode” Here toggle to set the display format to be used during editing or reproduction (special language). 72 Programming 34 Display Formats Instruction list IL The following applies to DOLOG AKF A120: In IL OBs, PBs and FBs are programmable. A maximum of 45 input or output operands can be defined in the declaration part of an FB, but not more than 64 parameters in total. Only formal operands defined previously in the declaration part are accepted in the IL of a user functional block, and each formal operand muct be preceded by an ”=” sign. This enables it to be clearly distinguished from a generally valid symbol name. A maximum of 24 jump marks are possible within a user FB per network. Likewise, there are also PB and FB calls (conditional or unconditional) in IL. During network creation in IL the DOLOG AKF software carries out syntax checks, so that impermissible input is refused. Rules for constructing an instruction list Network start / end Example: : U..., O... or L... Each network must start with the operations U, O (for logic) or L (for arithmetic) : *** and end with ” *** ”. initiating pulse The system marker SM2 (switch–on marker) is used as an initiating pulse. The valency of the switch–on marker is only for the 1st cycle = 1. Utilization: For initializing the actual values of timers and counters in hot restart operating mode when powering–up or on program start. For details of how to program memories with preferred state after power–up, see ”Memory”. 34 Programming 73 Marker bit Example Network 001 : A I2.1 : A I2.2 : O I2.3 : = M5.1 : *** Network 002 : A I2.4 : A M5.1 : = Q3.1 Markers (binary intermediate results) save the results of logical operations for use elsewhere in the program. They have to be defined before the scan. For nesting, it is advisable to work with markers or bracket operations. Bracket operations (only in IL) Example : A ( Bracket operations can also be used in place of : A I2.1 markers. : A I2.2 After an instruction ”Open brackets”, just as at the start of : O I2.3 the program, the next instruction has to begin with A or O. : ) The maximum nesting depth for bracket operations is : A I2.4 13. The number of ”Open brackets” operations must be the same as:=Q3.1the number of ”Close brackets” operations. : *** Block end The last network of each block contains only the ”block end”: : BE 74 Programming 34 Logic functions Order of logic operations Example : A I2.1 When logical operations are being calculated, the rule ”AND : A I2.2 before OR” is applied, as in Boolean algebra, I.e. no superfluous brackets must be entered. : O I2.3 The accompanying IL obeys this rule : O I2.4 (I2.1 ∧ I2.2) ∨ I2.3 ∨ I2.4 = Q3.1 : = Q3.1 : *** Normalizing operations Instruction with normalizing Example : U E2.1 With the operations such as S..., R... the link result is : S M5.19 normalized. The result cannot be used directly for the next : U E2.2 instruction. Consequently, the following instruction must always start with operation U or O. The : *** same behavior applies to the instructions U(, O(, X(, UN(, ON(, XN(. Instruction without normalization : U M5.4 The result of logic operation UM5.4, UM5.5 is not normalised on : U M5.5 assignment of ”=”, i.e. it is available for further assignments : = M5.6 (multiple assignment is possible). : = M5.7 : = M5.8 : U E2.7 Prior to execution of the subsequent ”AND” operation the register is first normalized, i.e. erased, so that the previous : *** result of logic operation can no longer be used. 34 Programming 75 Connector With the connector, =C, a signal is placed on an intermediate marker or register. The register is not initialized (reset), so networks can be saved. The marker type must be congruent with the operands of the other instructions in the command sequence. Examples Logic : A M3.2 : A M4.5 : =C M3.5 : O M4.8 : = Q3.7 : *** Arithmetic Network 001 : L K12 : ADD MW1 : =C MW30 : SUB MW2 : = MW44 : *** Network 002 : L MW30 Intermediate result from NW001. : : : 76 Programming ADD = BE MW15 MW45 34 Save operations The sequence of IL commands must be strictly followed. The preferred state after power–on (startup marker) SM2 or additional instructions before the ”=” assignment are optional. In cases where no additional instructions precede the ”=” assignment, the marker M* can also be replaced with Q3.*t in the examples mentioned below. Example: SR memory, dominant resetting, preferred state after power–on 1 : U ( : O E2.1 : O SM2 The system marker SM2 has a ”1” signal in the 1st program cycle, : ) therefore preferred state after power–on 1. : S Q3.1 : A I2.2 The reset condition is processed after setting, hence : R Q3.1 dominant reset. : = Q3.1 : *** Example: pk memory, dominant setting, preferred state after power–on 1 : U E2.2 : R A3.2 : U ( : O E2.1 The system marker SM2 has a ”1” signal in the 1st program cycle, : O SM2 therefore preferred state after power–on 1. : ) : S A3.2 The set condition is superordinate to the reset condition, i.e. : = A3.2 dominant setting. : *** Note For examples of dominance, preferred state after power–on 0 and preferred state after power–on 1 refer to page 100. 34 Programming 77 Counters Please adhere strictly to the command sequence C, S, L and R in order to avoid syntax errors. There can be additional instructions between commands. CU, counter up 0 ... 32 767 Example: : A I2.1 Counting pulse input (count with 0 1 edges on I2.1). With the first edge, the counter output is set to ”1”. : CU Z10 C10, up counter. : A I2.2 With ”1” signal on I2.2, the setpoint value is loaded with K30. : S C10 : L K30 : A I2.3 Reset input (actual value and counter output are set to ”0” : R C10 with ”1” signal on I2.3). : = Q3.1 When actual value = setpoint value: ”0” signal on Q3.1.

There are 5 timer functions available. The associated timing diagrams can be found under ”FBD elements”. Please adhere strictly to the defined command sequence in order to avoid syntax errors. There can be additional instructions between commands. Example: TI, pulse (monostable–circuit – monoflop) : A I2.1 Start (input signal) timing element T30 : SI T30 : DZB 100MS Define the time base in ms: 10, 100 or 1000 or input 10MS, 100MS, 1000MS : L K30 load the constant K30 for the setpoint value : U E2.2 reset the time block : R T30 : = A3.1 With 0 1 edge on I2.1: ”1” signal on O3.1. TV, extended pulse : A I2.1 : SV T31 : DZB 100MS : L TSW30 : A I2.2 : R T31 : = Q3.1 : *** TS, stored on–delay : A I2.1 : SS T33 : DZB 100MS : L MW32 : A I2.2 : R T33 : = Q3.3 : *** 80 Programming TE, on–delay : : : : : : : : A SE DZB L A R = I2.1 T32 100MS TSW31 I2.2 T32 Q3.2 *** TA, off–delay : : : : : : : : A SA DZB L A R = I2.1 T34 100MS MW33 I2.2 T34 Q3.4 *** 34 Edge recognition The following operations are able to detect pulse edges. FLP FLN FL Detection of an edge transition Detection of an edge transition Detection of edge transitions Examples FLP : A I2.1 : FLN M1.10 : = M1.11 : *** FLN : A : FLP : = : *** I2.1 M1.10 M1.11 0³ 1 1³0 0 ³ 1 and 1 ³ 0 FL : : : : U FL = E2.1 M1.10 M1.11 *** Shift (only in IL) These operations can be used to shift the contents of the register by a user–defined number of bits. The moved bits are lost. Sign information would be lost. Therefore, shift is only sensible in logic. 1 0 1 0 0 1 1 0 Example: SHL, shift : A : SHL : = : *** → Shift to the left by 3 bits, SHL K3 → 0 0 1 1 0 0 0 0 to the left MB1 The contents of MB1 are moved 3 bits to the left. K3 SHL is only possible with constants. MB1 The moved value is in MB1. Example: SHR, shift to the right : A MB1 The contents of MB1 are moved 5 bits to the right. : SHR K5 SHR is only possible with constants. : = MB1 The moved value is in MB1. : *** 34 Programming 81 Rotate (only in IL) These operations can be used to rotate the contents of the register by a user– defined number of bits. The rotated bits are reinserted in the opposite direction. 1 0 1 0 0 1 1 0 → Rotate to the left by 4 bits, ROL K3 → 0 1 1 0 1 0 1 0 Example: ROL, rotate to the left : A MB1 The contents of MB1 are rotated 4 bits to the left. : ROL K4 ROL is only possible with constants. : = MB1 The moved value is in MB1. : *** Example: ROR, rotate to the right : A MB1 The contents of MB1 are rotated 5 bits to the right. : ROR K5 ROR is only possible with constants. : = MB1 The moved value is in MB1. : *** Incrementing/decrementing (only in IL) The following functions can be used to increase or decrease the contents of a byte, word or doubleword by 1. This is used to modify setpoint values, for example. INC DEC increase value by 1 decrease value by 1 Example INC : A MW1 : INC : = MW1 82 Programming DEC : A : DEC : = MB1 MB1 34 Load, Transfer (only in IL) LBB, LBW: bit ³ byte, word Operations LBB and LBW are used to load (read into the register) a defined bit string (byte register, word register). The operand following the load operation is the least significant binary signal of the bit string. Upon input, an equipment list dependent syntax control of the acceptability of the bit string is carried out. TBB, TBW: byte, word ³ bit Operations TBB and TBW assign the register contents (binary) to a bit string. The transfer begins with the bit of least significant value from the register content. The start of the bit string is determined by the operands. In order to avoid damage to memory areas and undesired memory content, a function is introduced in which the user states the width of the bit string. The statement of bit string width is carried out with the command DBB ANZ xx Define bit string width The operand number (ANZ) can accept the following values: LBB, TBB with bit operand DBB ANZ 1...8 for maximum 8 bits in byte register Formal parameter in FB declaration part: B8 LBW, TBW with bit operand DBB ANZ 1...16 for maximum 16 bits in word register Formal parameter in FB declaration part: B16 LBW, TBW with byte operand DBB ANZ 1...2 for maximum 2 bytes in word Formal parameter in FB declaration part: B2 Rules for creating IL: It is absolutely necessary that the instruction DBB directly follows its bit string instruction. In the formal parameter declaration, the declaration for the number must directly follow the declaration of the address. Otherwise, testing and assignment are not possible. The declaration of the setpoint types B2, B8 and B16 must be followed by the declaration of a setpoint type ANZ. 34 Programming 83 Note The maximum number of instructions and moved bits (DBB ANZxx) in a user function block is < 1,000.

Programming 85 LLD, LHD: Load Low Data/ Load High Data ³ word, doubleword The operations LLD and LHD load: bytes from the signal memory into the word register, or words from the signal memory into the doubleword register A word consists of a high byte and a low byte. The low byte contains the less significant word part, the high byte contains the more significant word part. Accordingly, a double word consists of a high word and a low word. With the command LLD the user can: define any byte as the low byte of a word, or define any word as the low word of a doubleword With the command LHD the user can: define any byte as the high byte of a word, or define any word as the high word of a doubleword 1 0 1 0 0 1 1 0 0 1 1 0 1 0 1 0 11 1 0 0 0 1 0 0 0 1 0 0 0 1 0 27 27 27 27 20 LHD MB 20 LLD MB LHD MB 1 0 1 0 0 1 1 0 0 1 1 0 1 0 1 0 215 20 20 LLD MB 1 1 1 0 0 0 1 0 0 0 1 0 0 0 1 0 20 215 LHD MW 20 LLD MW 1 0 1 0 0 1 1 0 0 1 1 0 1 0 1 0 1 1 1 0 0 0 1 0 0 0 1 0 0 0 1 0 231 215 20 Examples: Using the operation LLD, the contents of MB112 (decimal 100) are loaded into the low word of marker word MW223. :L := :LLD :LHD := K0 MB113 MB112 MB113 MW223 86 Programming 00000000 01100100 00000000 00000000 01100100 34 Using the operation LLD, the contents of MW212 (decimal 32 612) are loaded into the low word of marker double word MD200. :L := :LLD :LHD := 34 K0 MW213 MW212 MW213 MD200 00000000 01111111 00000000 00000000 00000000 01111111 00000000 01100100 00000000 01100100 Programming 87 TLD, THD: Transfer Low Data/ Transfer High Data ³ word, doubleword The operations TLD and THD transfer: bytes from the word register into the signal memory, or words from the doubleword register into the signal memory A word consists of a high byte and a low byte. The low byte contains the less significant word part, the high byte contains the more significant word part. Accordingly, a double word consists of a high word and a low word. With the command TLD, the user can: define the low byte of a word as any byte, or define the low word of a doubleword as any word With the command THD, the user can: define the high byte of a word as any byte, or define the high word of a doubleword as any word 1 0 1 0 0 1 1 0 0 1 1 0 1 0 1 0 11 1 0 0 0 1 0 0 0 1 0 0 0 1 0 27 27 27 27 20 THD MB 20 TLD MB THD MB 1 0 1 0 0 1 1 0 0 1 1 0 1 0 1 0 215 20 20 TLD MB 1 1 1 0 0 0 1 0 0 0 1 0 0 0 1 0 20 215 THD MW 20 TLD MW 1 0 1 0 0 1 1 0 0 1 1 0 1 0 1 0 1 1 1 0 0 0 1 0 0 0 1 0 0 0 1 0 231 215 20 Examples Using the operations TLD and THD, the contents of marker word MW219 (decimal 1 024) are transferred into low byte MB117 (0) and MB118 (4). :L MW219 :TLD MB217 :THD MB118 88 00000100 00000000 00000000 00000100 Programming 34 Using the operations TLD and THD, the contents of marker double word MD17 (decimal 2 097 168) are transferred into low word MW220 (16) and high word MW221 (32). :L MD17 :TLD MW220 :THD MW221 00000000 00100000 00000000 00010000 00000000 00010000 00000000 00100000 The analog value EW5.1 (15 928) is loaded into the marker double word MD18.

The mark that is entered for the jump call must also be entered at the jump goal. Jump marks are introduced with an ”=” sign, just like formal parameters. The jump goal should be a load instruction, in the case of arithmetic, or the start of a logical connection, since the register is thereby initialised. Since the register is initialised after an assignment, this has an effect on the jump goal (see Example SPB, conditional jump) Example: SP, unconditional jump : A I2.1 Jump mark goals are entered to the left of : A I2.2 the colon. You will need to move the cursor there : = Q3.1 to do this (arrow keys or mouse). Jump marks : SP =AM0012 consist of up to six characters. The first of : ... these must be a capital letter. The rest of AM0012 : A Q3.1 the characters can be numbers, special characters or : ... letters, but spaces are not allowed. Example: SPB, conditional jump with initialization : S I2.3 : S I2.4 : SPB =AM0022 The jump is carried out : ... on a ”1” signal. : = M4.1 AM0022 : A I2.5 with initialization : ... AM0022 : = Q3.2 without initialization Note 90 Reproduction of the jumps in LD and FBD is not available. Programming 34 NOP instruction (only in IL) The ”NOP” instruction is a dummy for an operation. Note ILs with ”NOP” instructions cannot be reproduced in LD or FBD. FREE instruction (only in IL) FREE is a dummy in instruction list. Unlike NOP, which can stand for any instruction, FREE is only valid for inputs from memories, timers and counters. Example: without dummy : A I2.1 : SV T31 : DZB 100MS : L K10 : A I.2 : R T31 : = Q3.1 : *** 34 : with dummy : A I2.1 : SV T31 : DZB 100MS : L K10 FREE : = Q3.1 : *** In this network, note that the time block cannot be reset when it is with dummy. Programming 91 Arithmetic functions Load Arithmetic Functions are always with ”L”. Constants Constants K, KO and KH are loaded with operation ”L”. Calculating Essentially all arithmetic operations must begin with a load operation. Example : L K12 : ADD MW1 Several arithmetic commands may follow each other : SUB MW12 : = MW20 : *** : L rule. : MUL : ADD : = : *** MW22 In the case of arithmetic there is no ”point-before-dash” MW33 MW11 MW44 The expression <MW11> + <MW22> x <MW33> = <MW44> must be programmed as shown here. It is possible to convert between data types, see ”Converting”. Brackets cannot be used in arithmetic commands. If intermediate results are to be used later, intermediate marker must be inserted. Overflow markers are set when executing arithmetic operations. You will find these in the user instructions ”A120 Pocket Guide”. Each type of operand has its own overflow marker. If system markers are to be used, they must be called directly after the arithmetic operation. 92 Programming 34 Generating two’s complement For BCN switches with a separate sign, the two’s complement should be calculated for negative values. + – 0 0 0 0 0 : : : : : 9 9 9 9 9 0 ... 32 767 I2.1 ...

If you do not require reproduction in LD/FBD, arithmetic instructions are permissible between load and comparison operations. Several instructions on bit logic operation can precede the ”=” assignment. = : : : : equal to L MW30 == MW31 = Q3.1 <> : : : : 94 *** does not equal L MW32 <> MW33 = Q3.4 *** Programming > : : : : greater L > = than MB30 MB31 M5.22 : : : *** < less than L K20 < MW51 = Q3.3 : *** ≥ greater than/equal to ≤ less than/equal to : : : : : : : : L >= = *** MD40 MD42 M5.23 L <= = K21 MW52 Q3.6 *** 34 Conversion Note Two types of processing and various operand types exist. The possible conversions occur automatically. The user can use mixed operand types and mixed types of processing in IL. The following functional description makes clear how the values in the dynamic display arise. Converting into other operand types Logic: Operand types without a sign bit, byte, word and double word Arithmetic: Operand types with a sign byte, word and double word Conversion is always from a smaller to a larger operand type. Logic: Operand type without sign; when converting, the more significant unassigned bits are filled with ”0”. Example: Converting from MB to MW 0 0 1 0 0 0 1 0 27 20 0 0 0 0 0 0 0 0 0 0 1 0 0 0 1 0 215 20 Arithmetic: Operand types with sign; when converting, the more significant unassigned bits are filled according to sign. More significant bits with positive values are filled with ”0”. More significant bits with negative values are filled with ”1”. Examples: Converting from MB to MW. 34 Programming 95 0 0 1 0 0 0 1 0 27 20 1 0 1 0 0 0 1 0 27 20 0 0 0 0 0 0 0 0 0 0 1 0 0 0 1 0 215 20 1 1 1 1 1 1 1 1 1 0 1 0 0 0 1 0 215 Conversion between two types of processing (logic ³ ³ logic) 20 arithmetic, or arithmetic The conversion from logic to arithmetic is always without sign. The conversion from arithmetic to logic is always with sign. 96 Programming 34 ladder diagram LD In the LD the OBs, PBs and FBsare programmable. Per ladder diagram network, as inputs, a maximum of 16 signals in parallel and 7 signals plus output in series can be linked. There is only one output per LD network. This cannot be negated. The valence of the output signal can be set on a maximum of 16 contacts. No jumps are valid in the LD, only block calls. Processing of the called block is followed by return to behind the place that called. In LD, a program or function block can only be alone in a network. When generating networks in LD, one must be aware that the elements can only be entered in certain cursor positions. The following symbols can be selected when generating networks in LD: normally open contact (inquiry 1 signal) normally closed contact (inquiry 0 signal) connector =2k+1 exclusive OR block connection of parallel paths continuation in parallel path without contacts output (not stored) FBD elements further elements that can be called in LD and FBD (memories, timers, counters and comparators) can be selected and called. Note on FBD elements: Normally, when programming in LD, only one FBD element per network is possible. Exceptions are several timers, counters, memories beside one another in the upper cross– path. 34 Programming 97 possible not possible M0.1 M0.1 S S M0.2 M0.2 R Q S R Q R Q S M0.4 M0.3 R Q M0.1 S M0.4 M0.2 R Q Figure 2 Inputting FBD elements into a ladder diagram 98 Programming 34 Function block diagram FBD In the FBD the OBs, PBs and FBs are programmable. Function block diagram allows a maximum of 6 FBD elements per network horizontally, and 46 input signals together with a maximum of 12 FBD elements with two inputs each vertically. There is only one output per FBD network. This cannot be negated. The valence of the output signal can be set on a maximum of 16 contacts . In FBD there are no jumps, instead only block calls. Processing of the called block is followed by return to the place from which the call was made. In FBD, a program or function block call must always be alone in a network. For generating networks in FBD, it is important to note that elements can only be entered at certain cursor positions. The following symbols can be used for geneating networks in FBD: & >=1 =2k+1 FBD elements: 34 AND block OR block exclusive OR block input (inquiry 1 signal) negated input (inquiry 0 signal) connector The elements that can be called in LD and FBD (memories, timers, counters and comparators) can be selected and called. Programming 99 FBD Elements The FBD elements are standard blocks which you can select in the FBD or LD Editor. All AKF functions (FBD elements) show latching properties, i.e. following momentary power drop–out on the PLC all signals and words are unchanged. To achieve initial state characteristics (initialisation upon voltage recovery), the system marker SM2 should be used as the initialisation input of the function. An example of each FBD element is shown below.

The actual and setpoint counter values can be scanned using a load assignment and transferred to other operand areas. 102 Programming 34 CUD, up/down counter –32 768 ... +32 767 Z12 I2.1 Z+ input Z- input Z+ Set I2.2 Z– Reset I2.3 S Output K30 SW I2.4 R Actual value Q Q3.2 setpoint value Preset value default Figure 5 FBD element and timing diagram counter up, down With a ”1” signal at reset input ”R” the actual value and the output are set to ”Q” and the system marker SM26 to ”0”. With a 0 1 edge on set input ”S”, the setpoint value ”SW” is imported into the set point value register. The actual value remains unchanged. Only after at least one setpoint value has been accepted, is a preset value/actual value comparison undertaken. The permissible setpoint values ”SW” are: K, MW, ZSW The output ”Q” is set to ”1” as soon as the actual value is greater than or equal to the setpoint value. With a 0 1 edge on input Z+, the actual value is increased by 1. With a 0 1 edge on input Z–, the actual value is reduced by 1. If as a result of the next count operation of the counter the actual value became greater than 32 767 or less than -32 768, then the system marker SM26 (actual value overflow) is set to ”1”.

Note Note that all the Functions except ”Link Program” and ”EPROM processing” are only possible with a properly connected PLC. The PLC ”A120” is only to be connected to the serial port COM1 of the PaDT. The EPROM programming station kit ”EPS 2000” is connected to the serial port COM1 of the PaDT. The following loading functions are available under this pulldown menu: Edit Load Online Print Special Setup Help=F10 Linl Program Program to PLC Exchange Online Read Equipment list Read out PLC Compare Set Date / Time Process EPROM Bootload 138 Programming 33 3.4.1 Link program - ”Load”, ”Program Link” When this function is selected, the PLC program is generated . Here the OB and all blocks called by the OB are together links into the run–ready SPC program. This completely program is stored in the file ”CODE.PLC” and can then be transferred to the PLC using the function ”Program to PLC”. Linking takes place with the link mode and ALU type set in ”Setup”, ”PLC station”. In Link Mode you can determine the extent of the additional information to be transferred into the PLC. Complete Representation: This setting enables an unrestricted representation of the IL. Here the representation is not of the symbols and comments from the data block, but of line comments, network comments, parameter symbols and labels. Comments, symbols and labels are identical to the original. without comments : As complete representation, with the restriction that the comments are no longer available. without comments, symbols and labels: No comments, symbols or labels are available for the representation. Only the structural information required for reproduction are transferred to the PLC. Without Representation: A representation is no longer possible with this setting.<F 6Ã@R@Z7@Lge>. Automatic Adjustment: If the program is too large with complete reproduction, the link mode is switched back to the level at which the program still fits into the PLC. 33 Programming 139 3.4.2 Program to PLC - ”Load”, ”Program to PLC” This function transfers the linked program and the equipment list to the PLC. If the program file check (”CODE.PLC”) finds that an ”Online exchange” has already taken place after linking a safety inquiry is made as to whether the transfer should really take place. If the IL area of the PLC is equipped with an EPROM, loading is terminated. 3.4.3 Exchange online ”Load”, ”Exchange online” - ”Edit”, ”Blocks”, ”Start entry”, ”existing block, <Ctrl>+<Return>, ”Exchange online” - ”Edit”, ”Overiew”, Select Block, <Ctrl>+<Return>, ”Edit Block”,.. This function allows you to load a new block into the program with the PLC running or stationary. In addition, a existing changed block in the program can be exchanged with the PLC running or stationary. Note New SFBs cannot be loaded into the PLC using this function. If new SFBs are to be loaded into the PLC the program is to be linked and loaded into the PLC. When approaching the limit of available memory, an online exchange may no longer be possible. In such a case, try to load the whole program into the PLC after relinking. 140 Programming 33 The following entries are available in this menu: Exchange Start Exchange Plock Number 1 Block Typ OB Start exchange ”Load”, ”Exchange online” - ”Edit”, ”Blocks”, ”Start entry”, ”existing block, <Ctrl>+<Return>, ”Exchange online” - ”Edit”, ”Overiew”, Select Block, <Ctrl>+<Return>, ”Edit Block”,.. After determining the block to be exchanged (type and number), the exchange is carried out.Small windows indicate at what point you are in the process. 3.4.4 Read Equipment list - ”Load”, ”Read Equipment List” This function reads the actual equipment of the PLC into the programming panel and saves it in the file ”BES.DAT” (of the current station). If ”BES.DAT” already exists in the station it will be overwritten following an inquiry! 33 Programming 141 3.4.5 Read out PLC - ”Load”, ”Read out PLC” This function is used to read out from the PLC: individual blocks or the complete program including equipment list Then use the following functions to select the desired Block list and set the desired system and station: Read out PLC Start Read out To Plant: C:\AKF125 Station name: BEISP Block list X Load Block list Store Block list Start read–out - ”Load”, ”Read out PLC”, ”Start PLC Read-Out” After specifying the blocks to be read out (possibly present, i.e. block list to be loaded) reading out from the PLC to the declared system and station is started. If this system and station already exist the station will be overwritten following a safety inquiry. If the system and/or station do not yet exist, they will be created following confirmation. 142 Programming 33 Read out to system - ”Load”, ”Read–out PLC”, ”To system” Here you can determine the system to which the blocks read out will be written. The preset for this system directory is the system set in the PLC.

This function transfers the complete user program and the equipment list from the PLC into the PaDT (in file ”CODEAUS.120”). Its content is identical to the file ”CODE.PLC”, from which the user program was transferred. The file can be backed up and restored, so that if necessary the same EPROMs can be burned again and again. If the file is used to program further EPROMs, it should be copied to the name ”CODE.PLC”. Instead of the PLC the EPS 2000 must now be connected to the serial port of the PaDT. 154 Programming 33 3.4.9 Bootload - ”Load”, ”Bootload” This function is used to load the basic software into the RAM structure of an ALU 201L or ALU 202L (”RAM ALU”). To do so, make an ordinary connection between the PLC and PaDT (RS–232C). Bootloading via the programming interface (PaDT) will be carried out if: no PC001 is inserted a blank PC001 is inserted the PC001 contains only the user program (e.g. ALU bootloaded and with AKF125 user program V. 4.0 on PC001) Bootloading of the PC001 will be carried out if: the PC001 contains the basic software and the user program (e.g. ALU bootloaded and with AKF125 user program V. 4.0 on PC001) With a PC001 programmed with AKF125 and the PaDT-ALU connection the basic software will always be loaded from the PC001. The ”Bootload” function then brings about the GSW lading from the PC001. Note The yellow LED on the ALU flashes until the basic software is loaded or in the event of a transmission error. The function ”Bootload” must then be carried out. For the meaning of the various flashing frequencies please see the module description for the corresponding ALU.

DRU 096 - ”SeTup”, ”Print”, ”Output unit”, ”Printer”, ”DRU096” This is where you choose between: 33 Programming 223 DRU 120 - ”SeTup”, ”Print”, ”Output unit”, ”Printer”, ”DRU120” This is where you choose between: DRU 292 - ”SeTup”, ”Print”, ”Output unit”, ”Printer”, ”DRU292” This is where you choose between: 224 Programming 33 DRU 293 - ”SeTup”, ”Print”, ”Output unit”, ”Printer”, ”DRU293” This is where you choose between: PRT 294 - ”SeTup”, ”Print”, ”Outout unit”, ”Printer”, ”PRT294” This is where you choose between: 33 Programming 225 PRT 295 - ”SeTup”, ”Print”, ”Output unit”, ”Printer”, ”PRT295” This setting is used to initialize PRT 1 and PRT 294 The selection is effected here between: DRU 1200 - ”SeTup”, ”Print”, ”Output unit”, ”Printer”, ”DRU1200” This is where you choose between: 226 Programming 33 Printer_xyz - ”SeTup”, ”Print”, ”Output unit”, ”Printer”, ”Printer_xyz” This is where you choose between: Lines/page - ”SeTup”, ”Printer”, ”Lines/Page” You can specify the number of lines per page corresponding to the paper format which is used in your printer here with the aid of the line editor. Note Note: If using purely DIN A4 printers no more than 32 characters of signal comment may be input, otherwise pagination after 132 character will bring about line displacement. Of the AEG printers the DRU 120 and DRU 292 are affected. Page advance ”SeTup”, ”Print”, ”Form feed” The outputs can be carried out with or without form feed, depending on the type of printer used. If the form feed is switched off, the print program outputs a number of lines which corresponds to the number of blank lines. You can toggle between ”on” and ”off”. 33 Programming 227 Upgrade of printer driver To include a new printer in the AKF system you only need a simple editor, with which you edit the file ”DRUAKF40.DRV” in the sub–directory ”AKF12”. Up to 15 printers can be entered into this file. A printer description is started with the name ”Printer=”. The name which follows is displayed by the AKF software in a pulldown menu. There are then 3 initialization sequences to be entered in a hexadecimal representation. Please take note of capitalization. You will find the initialization sequences in the printer manual. Examples: Printer=DRU293 parallel/serial 1B3C Initialization 12 Switch to 80 characters 0F Switch to 132 characters Printer=DRU096 parallel 1B3C Initialization 12 Switch to 80 characters 0F Switch to 132 characters 228 Programming 33 Defining the Epson Fx-80 Printer=Epson FX-80 parallel 1C1B04 Initialization 040577 Switch to 80 characters 0F444488 Switch to 132 characters Caution When using a serial interface, you must have the following setting in the operating system before starting the AKF: MODE COM1:96,,,,P or MODE COM2:96,,,,P There are restrictions with reference to: Character set: Cable Assignment: 33 The IBM graphic character set is required. see printer manual and PaDT. Programming 229 3.8.4 Colors ”SeTup”, ”Colors” If your PaDT is equipped with a color monitor and the corresponding board, you can set the colors by yourself. You may set the colors for pulldown windows, help windows and message windows as you like. The software has to be called with the extension ”/COL”. Furthermore, you may use the screen parameters ”/GR” for grey scales and ”/BW” for black and white. If the software is called with these parameters, the system uses fixed settings. Recommendation: Color monitor ”/COL”, liquid crystal display ”/BW”, monochrome monitor ”/GY”. If the software is called with the parameter /COL, a further pulldown menu appears for each window type. Here the color settings for the following sections of a window can be selected for the color selection: Pulldown window Window Part Frame Normal Text Inverse Text Catchword Inverse Catchword Background Inverse Background Help window Window Part Frame Normal Text Inverse Text Catchword Background Inverse Background Messages window Window Part Frame Normal Text Inverse Text Background Inverse Background 230 Programming 33 By selecting one of these menu lines, a window appears with a color palette from which you can select a color value. The current adjustment is visible in the demonstration windows. Press <Esc> to exit from the ”Colors” menu. The new Color settings will appear after you exit from the Setup pulldown menu. 3.9 Hardware Settings You will find information on initial start–up in the manual mentioned below.
