The root directory is the base directory for all log files, NC programs etc. If you have all your NC programs on a single disk or network drive, choose this drive as the root directory. If you have NC programs on multiple drives just choose one of the drives for now.

Check the Auto create directories field at the bottom of the dialog.

Close the configuration by clicking OK.

7. Starting the administrator client

The next step is to configure the server to communicate with your CNC's. This is done from the administrator client. To start the administrator client, click on the Client button on the server console.

For further information about the administration client, please refer to DNC-Max Client .

8. Setting up the first machine

If this is your first installation, two ports Machine A and Machine B will be listed in the administrator port list. These are the default configurations installed by DNC-Max.

If want to configure a machine that uses the standard protocol, you can rename the first port. You should choose a name that uniquely identifies the CNC, i.e. the location of the

CNC or the name of the operator.

To rename a port, select Port / Rename Port from the menu.

Installation 11

If you want to configure a machine that requires a special protocol like Heidenhain or

Mazak, delete the two ports shown in the list. To delete a port, select Port / Delete Port from the menu. Then add a new port by selecting Port / Add Port. For further

information on how to add new ports, please refer to Add a New Port .

4.2.5. Feed / Speed

To change the feedrate and/or spindle speed for a specific port, click on the port in the port list and select the Feed/Speed tab. The feed/speed tab is shown below. You must have user access rights to change feed and/or speed parameters. If you are not logged on, you will be prompted for the user password (if required).

The following section describes how to adjust the feedrate. The method for adjusting the spindle speed is identical to this.

All controls on this tab are disabled if the server is not licensed for feed/speed adjustment.

Online adjustment of feedrate and spindle speed.

The feedrate is adjusted using the controls inside the Feedrate frame, in the upper half of the dialog.

DNC-Max Client 34

The feedrate controls are: A slider, three feedrate indicators (In, Out and New), two fields to specify the minimum and maximum feedrates (Min and Max), a checkbox to select absolute adjustment, and an emergency button (red circle with white cross).

In addition to these controls, the Apply button, and the Direct Mode checkbox are shared between the feedrate and spindle speed controls.

Feedrate slider

The slider is used to adjust the feedrate.

There are two methods for adjusting the feedrate: Indirect and Direct. With the indirect method, you should select the desired feedrate by moving the feedrate slider, and the press Apply.

With the direct method, you just move the slider, and the feedrate is changed immediately, unless the selected port is configured not to insert feedrate information (Send On Adjustment = Send No Data), in which case, the feedrate is not changed until a new feedrate value is encountered in the input file.

By default, the indirect method is used. To enable direct mode, check the Direct

Mode field and press Apply. If you select another port, leave the feed/speed tab, adjust the max/min values or press the emergency button, direct mode will be disabled.

Absolute

When this field is checked, the feedrate is adjusted in absolute mode. When using absolute mode, the feedrate is adjusted independent of the feedrate specified in the transmitted file.

When moving the feedrate slider, the feedrate can be adjusted between the minimum and maximum values specified in the Min and Max fields.

If this field is not checked, the feedrate is adjusted in relative mode. In relative mode, the new feedrate is specified as a percentage value of the feedrate specified in the transmitted file.

Moving the slider in relative mode will adjust the feedrate from 0% to 300% of the value specified in the input file, i.e. if the last value encountered in the transmitted file was 1200, the feedrate can be adjusted from 0 to 3600. The resulting value is also checked against the maximum and minimum values specified in the Min and

Max fields. I.e. if the minimum value is 500 and the maximum value is 3000, the relative adjustment is limited to 500-3000.

If this field is disabled (grayed) it is because absolute adjustment is disabled for this port.

DNC-Max Client 35

The In field displays the current feedrate with no adjustment; this is the same as the last feedrate value found in the transmitted file. If no feedrate value has been found, this field shows "???", and you can't use relative feedrate adjustment, since there is no value to base the relative change on. If you need to change the feedrate value while the In field shows "???", you have to use absolute adjustment.

Out

The Out field displays the current feedrate, this is the same as the last feedrate value sent to the CNC.

If you are using direct mode this field shows the same value as the New field, unless the selected port is configured not to insert feedrate information (Send On

Adjustment = Send No Data), in this case the Out field will not change its value to match the New field until a new feedrate value is encountered in the input file.

If no feedrate value has been sent to the CNC, this field shows "???".

New

The New field displays the result of the selected adjustment.

If the result is not available, this field shows "???".

Min

This field shows the minimum allowed feedrate. To change the minimum allowed feedrate, change the value in the Min field and press Apply.

The minimum value must be between the minimum and maximum feedrate specified in the protocol configuration.

Max

This field shows the maximum allowed feedrate. To change the maximum allowed feedrate, change the value in the Max field and press Apply.

The maximum value must be between the minimum and maximum feedrate specified in the protocol configuration.

Emergency button

The emergency button is used to cancel any changes in feedrate adjustment.

If the selected port is configured not to insert feedrate information (Send On

Adjustment = Send No Data), the current feedrate adjustment is not canceled until a new feedrate value is encountered in the input file.

5. DNC-Max HOW TO

5.1. Add a New Port

This section describes how to add new ports to the DNC server. You will need one port for every connected CNC. The port configuration determines how the server should communicate with the CNC. Adding a new port requires administrator access rights.

To add a new port select Port / Add Port from the administration client, and enter the administrator password (if required). If you are administrating more than one server, you will be prompted to select which server the new port should be added to. In this case, select the server you wish to add the new port to, and press OK. The select server dialog is shown below.

If you do not have more than one server, this dialog is not shown.

Select which server the new port should be added to.

Enter a description (name) for the new machine in the Machine Description field. You should always use descriptions that uniquely identify your machines, like the location of the CNC or the name of operator. Only letters, digits and spaces are allowed in the machine description. The description can be 1-128 characters long, but it is highly recommended that you choose a short description with 5-20 characters, this way, the description takes up less space in the port list, and in log files etc.

DNC-Max HOW TO 42

Add port

Then select a template configuration from the Machine template configuration drop list.

The list of templates contains all the machines you have configured, and a list of default templates for different machine types. If you are going to clone on of your existing configurations, select the machine you wish to clone from the list, otherwise select the default template that matches your machine. The template also determines which protocol is used for the port, i.e. if you select Heidenhain FE mode template, the special

Heidenhain protocol is used.

When you have entered a description and selected the correct template configuration, press OK. If the server is licensed for this port, the port configuration is shown next. If the server is not licensed, i.e. the number of ports is exceeded, or the selected protocol is not valid for this server, you will receive an error message.

If you have a number of identical machines, start by completing the configuration for just one of them. When you have tested the configuration, and determined that it works correctly. Add new ports for the remaining machines, and use this configuration as template for the remaining configurations.

5.12. Specify Feed Data and Non-Printable

Characters

This section describes how to specify feed data and non-printable characters in DNC-Max.

Feed data is the term used for any information sent or received by DNC-Max that is not part of the actual file being transmitted.

The following is an example from the standard protocol configuration, where the CNC requires a '%' character followed by a ASCII 0 to signal end of transmission.

Send at end of feed.

This also demonstrates how to specify non-printable characters, using the standard ASCII name "NUL" preceded by a "\".

You can also enter "\0" to specify ASCII 0. But notice that the next time you open the configuration dialog, this has been converted into "\NUL".

The ASCII names for all non-printable characters (ASCII 0 ASCII 31 and ASCII 127) are

listed in ASCII Table .

If you need to specify a non-printable character followed by one or more regular ASCII characters, you must insert a space after the ASCII name. Ex. "\EOT stop", the space

DNC-Max HOW TO 58 character will not be sent. To send a space after a ASCII name, you must enter two spaces.

Pay attention when you enter data in multi line input fields like Send data above.

If you press enter, the cursor will move to the next line, and server will send the specified data, followed by a newline (see below for further information).

An alternative solution to specifying %\NUL is shown below, in this case only '%' is specified in the Send data field, and the ASCII 0 character is instead send using the Send

character field.

Alternate solution to end of feed problem.

DNC-Max HOW TO 59

5.12.1. Specifying Multiple Lines

In all multi line input fields you can enter more than one line. The following is an example from the standard protocol configuration, where the CNC requires a line containing "M30", followed by a line containing "%".

Send multiple lines at end of feed.

Notice that the cursor is at the beginning of the next line following the line containing

"%". This happens if Enter was pressed at the end of the "%" line. After each line, the server will send the newline character(s) specified for the port. The result is shown in the terminal window below.

Result of sending feed data with linefeed.

DNC-Max HOW TO 60

If you do not want to send newline characters after the last line, make sure that you did not press enter, at the end of the last line.

To verify that no extra newlines have been entered, click with the mouse in the input field, below the last line you entered. If the cursor moves to the beginning of the next line, this indicates that you pressed Enter, if you do not want a newline character, press

Backspace to delete it.

The result of sending the two lines, where no newline is sent at the end of the second line is shown in the terminal window below.

Result of sending feed data with no linefeed.

DNC-Max HOW TO 61

5.12.2. Specifying Environment Variables

You can also specify environment variables in feed data. The example below is from the standard protocol, and it demonstrates how to ensure that the correct feedrate, spindle speed and tool number is used when you restart transmission from any point.

Access Control 64

6. Access Control

This section describes how to configure and use access control. Access control enables you to limit the number of persons that can configure and/or control you DNC servers.

There are two levels of access control: Administrator Access and User Access .

To enable access control, you must specify a user and/or administrator password in the server configuration.

If you have multiple servers, and you have enabled access control, you should specify the same password on all servers. This is not a requirement, but it makes it a lot easier to administrate and control your DNC servers.

6.1. Access Control in the Server

When the server is locked, the only allowed operations are Start Client, Show Help and

About.

To lock the server, press the Lock button. The Lock button then changes to Unlock to indicate that the server is locked.

If you lose your administrator password, you will not be able to control the DNC server, and you must contact CIMCO support for information on how to reset the

administrator password.

If you have enabled access control, you should also check the Lock console on startup option in the server configuration.

To unlock the server, press the Unlock button. Then select Administrator or User from the logon dialog shown below.

Logon dialog.

Access Control 65

If access control is enabled for the selected user, you must specify the correct password in the password field. If access control is not enabled for the selected user, the password field is grayed, and you can just press OK to login.

When you are logged on as User it is possible to toggle the Log Show Time, Log Show

Date and Log Shows Errors Only options in the setup menu, and start the administrator client. All other menus and buttons are disabled (grayed).

If you log in as administrator, all operations are allowed.

For further information about the server console menus, please refer to Server Menus .

Even if access control is not enabled, it is possible to lock the server. This prevents that anyone inadvertently stops the server, or change any configuration options. To unlock the server when no access control is enabled, you do not have to specify a password in the login dialog.

6.2. Access Control in the Client

If you start the administrator client by pressing the Client button in the server console, you will be logged on to the server with the same permissions as you have in the server console. I.e. if you are logged on at the server console as User, you will be logged on as user in the administrator client as well.

If you start the administrator client from the start menu, or desktop icon, you are not logged on when the client is started.

The menus and buttons are not grayed in the Client if you are not logged on. Instead the

Client checks if the requested operation is permitted by the user currently logged on. If not, it prompts for the password required to perform the selected operation. I.e. if you are logged on as user and selects Configure Port, you will be prompted for the administrator password. If you enter the correct password, you are now logged in, and any subsequent operations can be performed without entering a password.

If you are logged on, and leave the computer, you can press the Lock button to log off all servers. If you are not currently logged on to any servers, the Lock button is grayed.

If you are controlling multiple servers from the same administrator client, and all servers are configured to use the same password, you will just have to specify the password the first time you attempt to perform a restricted operation.

Access Control 66

If you are controlling multiple servers from the same administrator client, and some servers are configured with different passwords, you will have to specify the password the first time you attempt to perform a restricted operation on each of the servers.

For a complete list of operations that requires user or administrator access, please refer to

User Access and Administrator Access .

Operations that are not linked to a specific port or server are allowed even if you are not logged on.

Access Control Example

Suppose you have 4 servers (DNCSRV1 DNCSRV4):



DNCSRV1

Administrator password = "ADMIN", and user password = "USER".



DNCSRV2

Administrator password = "ADMIN", and user password = "USER".



DNCSRV3

Administrator password = "ADMIN3", and no user password.



DNCSRv4

Administrator password = "ADMIN4", and user password = "USER4".

You have started the administration client from the console of DNCSRV2, where you are logged on as User.

You can then send/receive files and perform other user operations on servers 1-3 without entering a password, because you are already logged on with user password USER on server 2, and you can also control ports on server 1 and 3, because they either use the same user password, or have no user password (access control disabled for User).

If you try to send or receive a file on one of the ports located on server 4, you will be prompted for the user password ("USER4").

If you try to configure a port, or perform some other action that requires administrator access, you will have to specify the correct administrator password for the server where the port is located.

Access Control 67

If you are logged on as administrator on server 1, you will also be able to perform administrator task on server 2, since they use the same administrator password. But you must specify the correct password if you attempt to perform administrator task on either server 3 or 4.

Serial Communication Overview 68

7. Serial Communication Overview

This section contains general information about serial communication, and how to build a standard serial cable and a loopback device.

7.1. Serial Communication Standards

7.1.1. RS-232

Quite possibly the most widely used communication standard is RS-232 (Recommended

Standard 232, also known as Electronic Industries Alliance RS-232-C). This implementation has been defined and revised several times and is often referred to as RS-

232 or EIA/TIA 232. The IBM PC computer defined the RS-232 port on a 9-pin D sub connector (DE-9) and subsequently the EIA/TIA approved this implementation as the

EIA/TIA 574 standard. The RS-232 and the EIA/TIA-574 specification define two types of interface circuits: Data Terminal Equipment (DTE) and Data Circuit-Terminating

Equipment (DCE). The RS-232 standard is defined as the 9 Position Non-Synchronous

Interface between Data Terminal Equipment and Data Circuit-Terminating Equipment employing serial binary data interchange. Both implementations are in widespread use and will be referred to as RS-232 in this document.

RS-232 is capable of operating at data rates up to 20 Kbps at distances less than 15 meters. The absolute maximum data rate may vary due to line conditions and cable lengths. RS-232 often operates at 38.4 Kbps over very short distances.

The voltage levels defined by RS-232 range from -12 to +12 volts. RS-232 is a single ended or unbalanced interface, meaning that a single electrical signal is compared to a common signal (ground) to determine binary logic states. A voltage of +12 volts (usually

+3 to +15 volts) represents a binary 0 (space) and -12 volts (-3 to -15 volts) denotes a binary 1 (mark).

Serial Communication Overview 69

7.1.2. RS-422

The RS-422 specification (ANSI/TIA/EIA-422-B) defines the electrical characteristics of balanced voltage digital interface circuits. RS-422 is a differential interface that defines voltage levels and driver/receiver electrical specifications.

On a differential interface, logic levels are defined by the difference in voltage between a pair of outputs or inputs. In contrast, a single ended interface, for example RS-232, defines the logic levels as the difference in voltage between a single signal and a common ground connection. Differential interfaces are typically more immune to noise or voltage spikes that may occur on the communication lines. Differential interfaces also have greater drive capabilities that allow for longer cable lengths.

RS-422 is rated up to 10 Mbps and can have cabling 1200 meters long at 100 Kbps. RS-

422 also defines driver and receiver electrical characteristics that will allow 1 driver and up to 32 receivers on the line at once. RS-422 signal levels range from 0 to +5 volts. RS-

422 does not define a physical connector.

7.1.3. RS-485

RS-485 (TIA/EIA-485-A or RS-485) is backwardly compatible with RS-422; however, it is optimized for party line or multi drop applications. The output of the RS-422/485 driver is capable of being Active (enabled) or Tri State (disabled). This capability allows multiple ports to be connected in a multi drop bus and selectively polled.

RS-485 allows cable lengths up to 1200 meters and data rates up to 10 Mbps. The signal levels for RS-485 are the same as those defined by RS-422. RS-485 has electrical characteristics that allow for 32 drivers and 32 receivers to be connected to one line. This interface is ideal for multi drop or network environments. RS-485 tri state driver (not dual state) will allow the electrical presence of the driver to be removed from the line. Only one driver may be active at a time and the other driver(s) must be tri stated. The output modem control signal RTS controls the state of the driver. Some communication software packages refer to RS-485 as RTS enable or RTS block mode transfer.

RS-485 can be cabled in two ways: two wire or four wire mode. Two wire mode does not allow for full duplex communication and requires that data be transferred in only one direction at a time. For half duplex operation, the two transmit pins should be connected to the two receive pins (Tx+ to Rx+ and Tx- to Rx-). Four wire mode allows full duplex data transfers. RS-485 does not define a connector pin out or a set of modem control signals. RS-485 does not define a physical connector.

7.3.2. Loopback Device

A loopback is a device that sends the signal back through the same port as it is sent out of. It is used for testing purposes and is not used under normal operations.

To make a loopback device, you will need a 9-pin or 25-pin connector and three pieces of wire.
