CTI 5250-TI5 and 5251-TI5 Installation and Operation Guide
CHAPTER 1. DESCRIPTION
The Model 5250-TI5 and Model 5251-TI5 Access Modules provide a simple, yet flexible, interface
to the SIMATIC&reg; Series 500 and 505 Programmable Controllers. The Access Modules are
designed to monitor and (optionally) modify Discrete I/O (X/Y), Control Relays (CR),
Timers/Counters (TCP/TCC), V-memory (V), Word I/O (WX/WY), and Drums/Event Drums. PLC
memory locations are continuously monitored to detect internal PLC errors and user configured
alarms and event messages.
The Access Modules provide a rugged, compact panel for the operator, technician, and engineer who
need to access PLC memory locations without using a VPU or TISOFT. This interface provides the
ease of use and flexibility needed for numerous operation, diagnostic, and maintenance applications.
Included with each module is a menu-driven software configuration program which runs on IBMcompatible computers. (The configuration package is covered in Chapter 4 of this Installation and
Operation Guide.) By following simple command prompts, users can assign custom tag names to
PLC memory locations, define alarms and messages, select operator password, designate read-only
memory locations, and specify V memory locations for the transfer of real-time clock data. Once
created, the configuration file can be transferred to or from the battery-backed memory in the Access
Module.
1.1 Features
Compact, industrial panel mount design including NEMA 4 rated (water-tight) front panel
and convenient plug-in communications and power cables
Access to SIMATIC&reg; 500 and 505 PLC memory locations by address or tag names
Password protection for individual memory locations prevents unauthorized changes while
allowing all monitoring functions
Read-only option prevents altering critical data
Flexible alarm handling permits selection of partial or complete display interruption, alarm
storage, and event logging
Context-sensitive Help screens
Real time clock that can be transferred to user-specified V memory locations
Displays and dynamically updates PLC memory locations (tag names) embedded in user
defined messages

SIMATIC&reg; 500 and 505 Series Controllers are permanently stored in internal ROM (Read Only
Memory). Custom configuration parameters, including user-assigned tag names, alarms, and
messages, are stored in battery-backed RAM.
The Access Module software provides two command sets for the operator. The primary command
set allows the user to monitor PLC status and monitor/change X/Y, WX/WY, V memory, Drums,
Timer/Counter, and Control Relay (CR) locations. The auxiliary command set displays the status of
the Access Module, display and edit the Real Time Clock, create a screen to dynamically display
four (4) data points, set PLC communications baud rate, and upload/download a configuration file
to/from a PC running the TI5 Configuration Software program. Additionally, the Model 5251-TI5
permits the user to specify the time delay before the VFD Screen Saver is activated.
Procedures for using each of these commands are described in the Chapter 3.
1.3 Battery Replacement
The Access Module is equipped with an internal 3.6V Lithium battery that should provide memory
backup for approximately 8 years when operated in normal environments. Battery life can diminish
if the unit is subjected to extreme temperatures or frequent temperature cycles.
It is recommended that the unit be returned to CTI for service when battery replacement is required.
However, a qualified technician can access the battery by removing the rear panel. A replacement
battery can be ordered from CTI (Part #075-00009).

1.4 Front Panel Description
The Access Module front panel contains a data display (LCD or VFD), 20 key membrane keypad,
and four (4) status LEDs, as shown below.
Figure 2 Front Panel Description
An 80 character (4 Line by 20 Characters) Data Display is provided with each unit. Model 5250-TI5
contains a 1&quot; by 3&quot; LCD with wide viewing angle. Model 5250-TI5 includes a VFD with 5mm by
3mm character size.
The Keypad is used to access PLC memory locations, edit values, and specify the Auxilliary
Command set (described in Section 3.5).
The &quot;SHIFT&quot; LED is illuminated when the &quot;SHIFT&quot; mode is active. The next key pressed causes
the alternate (Blue-labelled) function to be called.
The &quot;MESSAGE ACTIVE&quot; LED is illuminated when an Event Message appears on one or more
lines of the data display. An Event Message is a special type of alarm that interrupts the data display
but does not create an entry in the Alarm Storage Queue. See Section 3.8 for details on messaging.
The &quot;ALARM ACTIVE&quot; LED is illuminated whenever one or more &quot;unacknowledged&quot; alarm
messages exist in the Alarm Storage Queue. Alarm Queue messages are created when the Access
Module detects an alarm condition configured for this action. See Section 3.7 for a description of
alarms.
The &quot;UNIT OK&quot; LED indicates that the Access Module is properly powered and operating
normally. If this LED is ON steady, the unit is communicating with the PLC. If the PLC is not
responding, this LED is flashing.

1.5 LCD Brightness Control
The Model 5250-TI5 Access Module contains an adjustment screw that allows contrast control for
the Liquid Crystal Display (LCD). This contrast control is located in the left side panel below the
LCD.
A small screwdriver of approximately 1/8 inch diameter may be used to adjust the contrast setting.
The range of control is slightly less than one full turn with factory setting about 50%. DO NOT
PUSH on the adjustment screw with the screwdriver.
1.6 Communications
1.6.1 Access Module to Personal Computer
The Access Module communicates with an IBM-compatible PC to provide upload/download of
custom configuration files to/from the PC. The PC must be running the TI5 Configuration Program
provided with the unit.
A cable must be connected between the Access Module PROGRAM Port on the rear panel and a
serial port (COM1 or COM2) on the PC. Communication cables may be purchased from CTI or
constructed according to the specifications described in Chapter 4 of this manual.
1.6.2 Access Module to PLC
The Access Module can be connected directly to Siemens&reg; Series 500 and 505 PLC Programming
Port via a standard communications cable. Cables required to interface to all Series 500 and 505
PLC's are available from CTI or can be constructed as described in Section 2.3.
The Access Module can communicate to the PLC through the PROGRAM Port by either RS-232 or
RS-422. This choice is determined by the selection of the proper communication cable. No internal
switching is required to select RS-232 or RS-422 operation.
PLC Communications Baud Rate can be set through the TI5 Configuration Program as well as
directly from the keypad using an auxilliary command function. Choices are 9600 or 19.2K baud.
The other communication parameters (7 data bits, odd parity, 1 stop bit) are fixed and cannot be
altered.
If communications with the PLC is disconnected or interrupted by excessive noise, the Access
Module UNIT OK LED flashes approximately once per second to indicate the problem.
1.6.3 Access Module Output through AUX Port
The AUX Port on the Access Module rear panel can be used for a second serial connection to a log
printer or message display. The pinout for this port is described in Section 2.4.
The AUX Port is configured as RS-232 DTE (Data Terminal Equipment) operation. This port can be
used for output only; serial input is not supported. AUX Port communications settings are fixed at
9600 baud, 8 data bits, no parity, 1 stop bit and cannot be altered.

ensure that the PLC Baud Rate is set to the same value as configured in the Access Module.
16
CTI 5250-TI5 and 5251-TI5 Installation and Operation Guide
3.2 Keypad Entry
Operation of the Access Module is controlled through the keypad. Included on the keypad are digits
0 - 9 for entering PLC memory addresses and data, and special function keys which access the
various features provided by the Access Module.
3.2.1 SHIFT Key
The blue SHIFT key works in conjunction with the dual function keys with blue and white labels
(i.e., WX/WY-DRUM and HELP/READ keys). When the SHIFT key is pressed, the SHIFT LED
lights and the alternate mode is enabled. If a dual function key is pressed with SHIFT mode enabled,
the alternalte (blue-labelled) function is activated.
The SHIFT function remains active only until the next key is pressed (even if that key does not have
a dual function). The one exception is the use of the PRE/NEXT key, where the SHIFT function
remains active until the SHIFT key is pressed again.
The following example demonstrates the use of the SHIFT key.
Figure 16 SHIFT Key
The following example selects a DRUM, clears the display, and then selects a WX/WY location.
Figure 15 Use of SHIFT Key to Select WX/WY
CTI 5250-TI5 and 5251-TI5 Installation and Operation Guide
17
The Access Module executes only &quot;valid&quot; key entries. HELP messages are used extensively to
prompt the operator as to the expected key sequence. When an invalid key is pressed, it results in
the display of a HELP message or is simply ignored. An invalid keypress will not result in corrupted
memory or program violation within the Access Module.
When a &quot;memory variable&quot; (X/Y, V, WX/WY) key is pressed, the selected memory type is
displayed. The Series 500/505 PLCs use certain memory areas for dual purpose, and the variable
type can be determined only after the address is entered. In this case, both memory types are
displayed until the READ key is pressed. The proper label is then displayed. This applies to X/Y
(Input/Output), WX/WY (Word Input/Word Output), and TIMER/COUNTER memory areas.
3.2.2 PRE/NEXT Key
The PRE/NEXT key is used to access tag names of similar memory type, scroll through HELP
Screens, scroll through alarms, and move to the next editable field. The NEXT function allows the
operator to scroll through the variables which have been defined by tag names. When the desired tag
is displayed, pressing the READ key selects it. The PRE (Previous) key, selected with the SHIFT
function, works like the NEXT key except that it allows scrolling in reverse order.
The following are examples of the PRE/NEXT key. The tag names used here are for example only,
real tag names are created during the configuration of the Access Module.
NEXT Key Operation:

In this example, the SHIFT function remains enabled until pressed a second time or until the CLEAR
key is pressed.
3.3 Reading PLC Memory Locations
The following sections outline the two methods which can be used to access, monitor, and edit PLC
memory locations. Examples of both methods are outlined in detail for each memory variable type.
3.3.1 Direct Memory Address Number
The Access Module allows all supported memory types to be accessed using the PLC memory
address number (V1658, WX52, X7, etc). This method can be used whether or not a configuration
file has been downloaded to the unit.
Memory variable limits are determined by installed PLC type, PLC configuration (set via TISOFT),
and Access Module limits (set by TI5 Configuration Program). If the Access Module is used without
a configuration file, it attempts to establish memory variable limits based on attached PLC
configuration. Default limits are used on some older PLC's.
If a configuration file has been downloaded, the Access Module permits monitoring and editing only
those memory locations within the limits set in the TI5 Configuration Program.
CTI 5250-TI5 and 5251-TI5 Installation and Operation Guide
19
3.3.2 Accessing Memory by Tag Names
A memory location can be accessed by tag name if a configuration file has been downloaded to the
Access Module. This allows an operator to access memory variables without having to know the
PLC memory address. For instance, &quot;PROX 203&quot; refers to &quot;X12&quot; and &quot;TANK VOL&quot; references
address &quot;V243&quot;.
To access memory locations using tag names, use the following general steps:
(1)
Use the keypad to select the memory type, (i.e. V, X/Y, Drum, Timer/Counter, or
WX/WY. Note that the selection of WX/WY requires the use of the SHIFT key
first.
(2)
Scroll through the user defined tag names for the selected variable type using the
PRE/NEXT key. Scrolling order for each variable type is based on the order that they
were defined in the TI5 Configuration File.
(3)
Press READ to display the data for that memory location.
Example:
Assume that the following tags are assigned to V memory. Tags are listed in the order that they were
created in the configuration file.
V17 = TEMP1
V300 = TANK VOL
V8 = TIME SEC
V120 = SPEED
When scrolling through these tags using the NEXT key, they are accessed in numerical order by
memor
y type.
This is

Figure 19 Scrolling Sequence
20
CTI 5250-TI5 and 5251-TI5 Installation and Operation Guide
Press the PRE key (SHIFT,PRE/NEXT) to scroll backwards through the tags for the selected memory
type.
After READ key is pressed, other tags of the same memory type can be accessed by pressing the
CLEAR key (to stop reading current location) and PRE/NEXT key to continue scrolling starting at
the last selected tag name. See Figure 20 for an example.
To access a different variable type, press CLR ALL (SHIFT, CLR ALL/CLEAR) to exit the current
mode and follow the general steps listed above for selecting a new memory location.

3.4 Editing a PLC Memory Location
The Access Module can be used to change memory locations and variables in the Series 500 and 505
PLC memory. The general procedure for altering memory locations is described below.
(1)
Display the desired memory location by PLC Address or Tag Name as shown in
Section 3.3.
(2)
Press ENTER to edit the data. If the location is configured as &quot;READ ONLY&quot; (as set
in configuration file), the message &quot;Write not allowed&quot; is displayed.
(3)
Use PRE/NEXT to move the cursor to the desired field. Some variables have more
than 1 field that can be edited.
(4)
Enter new data to be written via the keypad. To change a state of a discrete point
(X/Y,CR) or &quot;FORCED&quot; condition, press 1 key for &quot;ON&quot; or &quot;FORCED&quot; and press 0
for &quot;OFF&quot; or &quot;UNFORCED&quot;.
(5)
Press ENTER when entry of new data is complete.
If this location does not require a Password (as specified in configuration file), the
new value is written to the PLC. In this case, Step (6) is skipped.
(6)
The &quot;PASSWORD?&quot; prompt appears. Key in the 4-digit Password followed by
ENTER (default Password is 5250).
(7)
If the correct password is entered, the new value is written to the PLC. The Access
Module then returns to the previous screen and begins to read the selected memory
location.
(8)
Once a password has been entered for a location, the module will not ask for another
Password until a new variable is selected or no keys have been pressed for
approximately 4.25 minutes (254 seconds).

3.4.1 Entering Negative Numbers
The Access Module allows entry of negative numbers in support of &quot;Signed Integer&quot; numbers within
the Siemens&reg; PLC's. Negative numbers can be entered by the following procedure:
(1)
Display location by PLC memory address or tag name as described in Section 3.3.
(2)
Go into Edit mode and enter new value as described in Section 3.4. In order to
change value to a negative number, the entire number must be re-entered.
(3)
When new value is entered (and cursor is located to the right of the number), press
SHIFT ENTER to force the displayed number to be assigned a &quot;negative value&quot;.
This action results in a minus sign being displayed in front of the entered number.
(4)
Pressing SHIFT ENTER again removes the minus sign and treats the edited value as
a &quot;positive number&quot;.
(5)
Press ENTER to accept the displayed value.
Negative numbers cannot be entered for the following variable types:
X/Y, Control Relay, Timer/Counter, and V-Memory (specified as Unsigned Integer or BCD).
3.4.2 Variable Minimum/Maximum Limits
The Access Module attempts to prevent the entry of invalid data by assigning minimum and
maximum limits according to variable type as listed below:
X/Y and CR
Timer/Counter Preset
Timer/Counter Current
WX/WY
V Memory (Signed Integer)
V Memory (Unsigned Integer)
V Memory (BCD)
0 to 1
0 to 65535
0 to 65535
-32767 to 32767
-32767 to 32767
0 to 65535
0 to 9999
In addition, minimum and maximum limits can be specified for each location that is assigned a tag
name using the TI5 Configuration software.
If the operator attempts to enter a number which is outside the limits, the display will default to the
closest limit.
The following examples assume default limits.
Example 1:
If the operator attempts to enter 70000 into TCP22, the display defaults to 65535
(maximum value allowed).
Example 2:
If the operator attempts to enter -40000 into WX16, the display defaults to -32767
(minimum value allowed).

3.6 Using the HELP Key
The Access Module includes a context-sensitive &quot;Help&quot; system to guide operators through the
expected key entry sequence in order to display and edit PLC memory locations. The HELP key may
be pressed at any time to display help information about the procedure currently being performed.
The following example shows how the HELP key may be used to obtain detailed information about a
procedure. In this example, the operator is prompted for a password while editing a V-memory
location. The operator then presses HELP for more information.
Figure 51 Using HELP Function
When a HELP screen is displayed, the &quot;current&quot; and &quot;total&quot; number of Help screens pertaining to this
operation is displayed in the lower right corner. In this example, &quot;1/8&quot; indicates that the first of eight
Help screens is displayed, while &quot;2/8&quot; indicates the second of eight Help screens. The next Help
screen is displayed by pressing the NEXT key.
The HELP mode permits an operator to scroll through all of the Help messages using the PRE/NEXT
key. The CLEAR key may be pressed at any time to exit from the Help mode and return to previous
screen.

3.7 Alarms
The Access Module continually monitors all PLC memory locations that are associated with an alarm
condition as configured using the TI5 Configuration Program and downloaded into the unit. These
PLC memory locations are read &quot;in the background&quot; and values compared against the alarm limits
specified. The Access Module can read and evalute approximately 50-60 PLC addresses for alarms
each second. Alarms are reported as they occur as well as when they clear.
Event handling is determined by the response to the following question while specifying alarms in
the 5250/5251-TI5 Configuration Program:
Add Alarm to Alarm Queue (Y or N):
A &quot;(N)o&quot; response specifies the action as an event. An Event Message can be written to the
display (see Section 3.8), but an entry is not added to the Alarm Queue.
A &quot;(Y)es&quot; response specifies the action as an alarm. This results in a message being added to
the Alarm Queue. Optionally, a message can also be written to the operator display as
determined by the response to the following prompt in the Configuration Program:
Interrupt Display with Event Message (A, 4, or N):
A &quot;(N)o&quot; response causes the standard alarm message to be added to the Alarm Queue and
no message appears on the operator display. The &quot;standard&quot; alarm messages are formatted as
follows. Examples are shown in Figure 52.
Standard Analog Alarm Message:
ALARM: Tagname
AT Date, Time
OF Value
LIMITS: LowVal, HighVal
Standard Discrete Alarm Message:
ALARM: Tagname
AT Date, Time
CONDITION: Value, Status
Figure 52 Alarm Queue Message Examples
A &quot;(4)th Line Only&quot; response permits an &quot;Alarm Message&quot; and &quot;Alarm Termination
Message&quot; to be specified as part of the alarm definition. The &quot;Alarm Message&quot; overwrites
the 4th line of the display when corresponding tag value goes into alarm state. The &quot;Alarm
Termination Message&quot; overwrites the 4th line when the tag value returns to normal. Either
message can be left blank so that the operator display is not interrupted on the associated
event.
48
CTI 5250-TI5 and 5251-TI5 Installation and Operation Guide
The message added to the Alarm Queue consists of the &quot;standard&quot; alarm message with the
user message appearing on Line 1 (in place of ALARM: Tagname). If a custom &quot;Alarm
Message&quot; is not specified (left blank), the entire &quot;standard&quot; alarm message is added to the
Alarm Queue.
An &quot;(A)ll Lines&quot; response allows an entirely custom message to be added to the Alarm
Queue as well as written to the operator display. Alarm Messages for Lines 1-4 are specified
as part of the alarm definition.
When the tag value is detected in alarm state, the custom message is written to the operator
display. If any message lines are not customized (when no message is defined for that line),
the information currently displayed on the &quot;blank&quot; lines is not overwritten. The custom
message is also added to the Alarm Queue. The &quot;standard&quot; alarm message will appear in the
Alarm Queue on lines where custom messages are not specified (left blank).
See Event Messaging (Section 3.8) and 5250/5251-TI5 Configuration Program &quot;Help&quot; system for
details on specifying custom Alarm Messages.
When an alarm is detected, the &quot;ALARM ACTIVE&quot; LED is illuminated. This LED remains ON
until all alarms have been acknowledged by an operator. The following procedure is used to view
and acknowledge alarms in the Alarm Queue:
(1)
When &quot;ALARM ACTIVE&quot; LED is ON, Press SHIFT CLRALL to display the oldest
pending (unacknowledged) alarm in the Alarm Queue. The Alarm Queue can not be
displayed unless an alarm is pending.
(2)
Press CLEAR to acknowledge the displayed alarm. If this is the only alarm pending,
the &quot;ALARM ACTIVE&quot; LED will extinguish. Pressing CLEAR again exits the
Alarm Queue display and returns to the previous screen.
(3)
If other alarms are pending, the next oldest is displayed when the first is
acknowledged (by pressing CLEAR). As alarms are acknowledged, the display
continues to display newer alarms. When all alarms are acknowledged, the
&quot;ALARM ACTIVE&quot; LED goes OFF.
(4)
The operator may view alarms without acknowledging them by entering the Alarm
Queue and scrolling through the messages by pressing PRE/NEXT. Previously
acknowledged alarms are marked with a &quot;grave accent&quot; character ( ` ). As long as
CLEAR key is not pressed, the alarms remain pending and the &quot;ALARM ACTIVE&quot;
LED remains ON.
(5)
The Alarm Queue may be exited at any time by pressing SHIFT CLRALL. Any
unacknowledged alarms remain &quot;pending&quot; and the &quot;ALARM ACTIVE&quot; LED stays
ON. The oldest unacknowledged alarm is displayed when the operator re-enters the
Alarm Queue.
CTI 5250-TI5 and 5251-TI5 Installation and Operation Guide
49
3.8 Event Messaging
An Event Message is created as a result of a &quot;special&quot; alarm point that is NOT specified to be added
to the Alarm Queue for operator acknowledgement. When detected, the &quot;MESSAGE ACTIVE&quot; LED
is illuminated (instead of &quot;ALARM ACTIVE&quot; LED as done with normal alarms). The &quot;MESSAGE
ACTIVE&quot; LED goes OFF when the operator clears the display by pressing the CLEAR key.
Event Messaging is used to provide operator prompts and process status based on PLC values.
Custom Event Messages can be created to interrupt the entire data display or break through to
overwrite only specific lines.
&quot;MESSAGES&quot; are user-defined text strings which are associated with event conditions. Messages
are created as part of the alarm definition (in TI5 Configuration Program) and can be set to interrupt
the data display and/or be transmitted out of the AUX Port to an attached printer or display whenever
the associated event goes into alarm state or returns to normal status. The alarm definition specifies
whether the data display is not interrupted, (A)ll lines of the display are interrupted, or only the (4)th
line is overwritten.
If an event is detected where the interruption of All display lines has been selected, the messages
defined as Alarm Message 1 thru Alarm Message 4 for that &quot;Alarm&quot; will overwrite existing
information on the data display. If any of the Alarm Message 1-4 lines are left blank (so that no
message is defined for the line), the information on the &quot;blank&quot; lines are not overwritten. For
example, if &quot;ALARM1&quot; is defined so that All display lines should be interrupted, and messages are
created for Line1and Line 3 only (Line 2 and Line 4 are left blank). When &quot;ALARM1&quot; occurs,
existing text on Line 1 and Line 3 will be overwritten with the messages assigned in the alarm
definition, but existing data on Line 2 and Line 4 is not overwritten.
If the interruption of (4)th line is selected, the alarm definition screen permits an &quot;Alarm Message&quot;
and &quot;Alarm Termination Message&quot; to be specified. The &quot;Alarm Message&quot; overwrites the 4th line of
the display when the corresponding tag value goes into alarm state. The &quot;Alarm Termination
Message&quot; overwrites the 4th line when the the tag value returns to normal. Either message can be
left blank so that the display is not interrupted on the associated event.
Messages may be up to 20 characters in length. Messages can include all ASCII values between
01-7E Hex. Printable ASCII characters (20-7EH) are entered directly (ie,&quot; 1&quot; or &quot;A&quot;). Control
characters (01-1FH) are designated by &quot;/&quot; followed by the desired control character (ie, &quot;/L&quot; for
Form Feed or &quot;/M&quot; for Carriage Return). Control characters are primarily used to send special
character sequences to a printer or display attached to the AUX Port. A &quot;slash&quot; can be inserted into a
message by entering &quot;//&quot;.
It is possible to create a message without text that is not treated as a &quot;blank&quot; message (and
overwrites that line on the display). This can be done by creating a message that consists only of a
control character (such as &quot;/P&quot;).
50
CTI 5250-TI5 and 5251-TI5 Installation and Operation Guide
A message can contain one &quot;embedded tag&quot; that displays the tag value when that message appears on
the 5250/5251 screen. This embedded tag value is dynamically updated as long as the message is
displayed. Select &lt;F2&gt; to select a tag name when the message is created. Embedded tags are NOT
dynamically updated in the following cases:
(1)
when included in a message that interrupts only the 4th line of the data display (as selected
when&quot;4&quot; is entered in the &quot;Interrupt Display&quot; field while defining an ALARM)
(2)
when the message is transmitted out of the AUX Port (as selected when &quot;Y&quot; is entered in the
&quot;Transmit to AUX Port&quot; field while defining a MESSAGE)
Asterisks (**) are included in place of the tag value in these cases.
Reference the HELP system in the Configuration Program for details on Messaging.
3.9 PLC Errors
The Access Module continually monitors the PLC status and reports errors when detected. The
frequency that PLC errors are reported can be specified via the TI5 Configuration Program.
Appendix A contains a list of PLC Communications Errors detected and reported by the Access
Module. These are reported as Error Numbers.
Appendix B is a list of both Fatal and Non-fatal PLC Errors. These errors are reported as text
messages on the 4th line of the data display and transmitted out the AUX Port when detected. The
initial error (since last Configuration File download), and most recent error are displayed.
Refer to the appropriate SIMATIC&reg; manual to respond to PLC Communication and Fatal/Non-fatal
Errors.

CHAPTER 4. TI5 CONFIG PROGRAM SETUP AND OPERATION
4.1 Configuration Program Description
The diskette enclosed with the Access Module contains special configuration software that allows
true &quot;customizing&quot; for each application. The system designer can use the TI5 Configuration
Program to assign tag names to PLC memory locations, adding a level of independent external
intelligence to the PLC ladder logic program. Alarm conditions and event messages can then be
&quot;linked&quot; to these tagged PLC addresses to provide continually monitoring and reporting of
operational parameters.
In addition to tags and alarms, the Configuration Program allows a convenient method for selecting
various levels of protection for PLC memory - including &quot;Read Only&quot; flags, Password protection, and
specifying minimum and maximum limits for editing values. Complete file handling is provided
within the program with functions for loading from disk, saving to disk, printing, download to
module, and upload from module.
The 5250/5251-TI5 Configuration Program is provided on a 720K DSDD 3.5&quot; diskette and consists
of the following files:
5250-5.EXE
5250-5.MSG
5250-5.NDX
5250READ.ME
Program executable
HELP Message file
HELP Index file
Compatibility file (accessed from &quot;Utilities&quot; menu selection)
The Configuration Program includes a very informative &quot;context-sensitive&quot; HELP system that
provides detailed description of operation and expected input at every cursor position. HELP is
always available by pressing [F1] key.
Operation is very intuitive - just use the cursor keys to move the highlighted bar to an item and press
[ENTER] to select. The &quot;Help&quot; selection on the MAIN MENU (displayed at program startup)
provides a complete description of all menu items and features included in the current version.
4.2 Hardware Requirements
The Configuration Program will run on any IBM-PC, XT, AT, PS2, or IBM-compatible computer
system running PC-DOS or MS-DOS v2.0 or higher. The computer must have a minimum of 512K
of RAM, one serial port, and CGA, EGA, VGA, or Hercules monochrome display. Hard disk storage
is not a requirement but is useful if multiple configuration files are generated and stored.
