Use this command to view the current firmware version of the software (Software
Revision Level) for the module, as well as other important values. You may be
asked to provide this information when calling for technical support on the
product.
Values at the bottom of the display are important in determining module
operation. The Program Scan Counter value is incremented each time a
module’s program cycle is complete.
Tip: Repeat this command at one-second intervals to determine the frequency of program
execution.
Warm Booting the Module
Caution: Some of the commands available to you from this menu are designed for advanced
debugging and system testing only, and can cause the module to stop communicating with the
processor or with other devices, resulting in potential data loss or other failures. Use these
commands only if you fully understand their potential effects, or if you are specifically directed to do
so by ProSoft Technology Technical Support staff.
Some of these command keys are not listed on the menu, but are active nevertheless. Please be
careful when pressing keys so that you do not accidentally execute an unwanted command.
Press [W] from the Main menu to warm boot (restart) the module. This command
causes the program to exit and reload, refreshing configuration parameters that
must be set on program initialization. Only use this command if you must force
the module to reboot.
Transferring Module Configuration to the Processor
Press [Y] to transfer the module’s configuration data to the processor. Ladder
logic is required in the processor to receive and implement the updated
configuration. You will be prompted to confirm the transfer.
If the operation is not successful, an error code will be returned.
Code Description
0 Transfer successful
-1 Error transferring module configuration data (block -9000)
-2 Error transferring device definition data (blocks -9100 to -9103)
-3 Error transferring Master command list data (blocks -6000 to -6007)
After successful data transfer, the module will perform a warm-boot operation to
read in the new data.
Viewing Communication Status
Press [1] to view the communication status and statistics of the DFCM Network
for the module’s node address. This command is useful for troubleshooting
purposes.
