8.1 Basic Troubleshooting Steps
1 Verify that the module is installed correctly, and is communicating with the
processor.
2 Install the most current version of ProSoft Configuration Builder.
3 Note the color and behavior of the LED Status Indicators (lights) on the front
panel. Refer to the tables in the following section for examples.
o The Active light should be ON whenever the module is communicating
with the processor over the backplane. A processor must be positioned on
the main rack and powered up. If this light does not come ON, either the
module or the processor may be hung or offline. Power cycle the PTQ
module and the PLC processor.
o The Configure light should be OFF. If the light is ON, it is still possible to
communicate with the module, but the module and Master are prevented
from going into RUN mode. There are two conditions that cause the
Configuration light to be on:
First: The configuration files are missing or corrupt. Configuration files are
stored on the Compact Flash card inserted in the rear of the module.
Remove the Compact Flash card and transfer the configuration files from
your computer to the card using a card reader.
Second: The checksum values for the PROFIBUS network configuration
file have changed, but the processor did not acknowledge the
configuration change by returning the correct checksum values to the
module. Re-import the function block file using the procedure in the
following section.
Special Note: Transferring Configuration Data to Replacement Module. All module configuration
data (including PTQ, PROFIBUS Network, and Ethernet) are stored on the Compact Flash in the
PTQ module. Should a module failure occur, it is a simple matter of moving the Compact Flash
from the old module to the replacement module in order to transfer the configuration data.
