Correct any invalid data in the configuration for proper module operation. When

the configuration contains a valid parameter set, all the bits in the configuration

word will be clear. This does not indicate that the configuration is valid for the

user application. Make sure each parameter is set correctly for the specific

application.

If the APP, BP ACT and OK LEDs blink at a rate of every one-second, this

indicates a serious problem with the module. Call ProSoft Technology support to

arrange for repairs.

communication is possible. Check wiring and cables.

Physical network connection detected. This LED must be on

solid for Ethernet communication to be possible.

4.2.2 Clearing a Fault Condition

Typically, if the OK LED on the front of the module turns red for more than ten

seconds, a hardware problem has been detected in the module, or the program

has exited.

To clear the condition, follow these steps:

1 Turn off power to the rack

2 Remove the card from the rack

3 Verify that all jumpers are set correctly

4 If the module requires a Compact Flash card, verify that the card is installed

correctly

5 Re-insert the card in the rack and turn the power back on

6 Verify the configuration data being transferred to the module from the PLC

processor.

If the module's OK LED does not turn green, verify that the module is inserted

completely into the rack. If this does not cure the problem, contact ProSoft

Technology Support.
