The PM8xx is transmitting and the Tx1/Tx2 LEDs are flashing, but the connected device is not receiving data. OR The connected device is transmitting, but the Rx1/Rx2 LEDs are not flashing. • Check that the communication interface cable is connected. • Check the hand-shake signals. The Tx/Rx signals are flashing concurrently with transmission, but the messages are not being received correctly by the connected device. • Check that the baud rate, parity, and number of data and stop bits are as specified for the connected device. • Check that the handshake procedures are as specified at both ends. • Check that the driver routines are adequate, both in the controller and the connected device. • Disconnect power to the controller, wait a moment and then power-up again. • Halt the program and initiate a reset signal (INIT) from the PM8xx processor unit. CI853 supports hot swap. PROFIBUS DP – CI854/CI854A Section 5 Maintenance 214 3BSE036351-510 A PROFIBUS DP – CI854/CI854A Table 34. PROFIBUS DP CI854/CI854A – Fault-Finding Indication Possible Cause and Corrective Action Neither R(un) nor F(ault) LED’s are ON The CI854/CI854A board is in the process of being restarted or configured. Allow time for this to finalize. If the condition persists, and all other units on the CEX-bus have non-illuminated LEDs: • Check that a valid HW configuration including the CI854 is downloaded to the controller. • Check the CEX-bus fuse inside the PM8xx processor unit. • Initiate a reset signal (INIT) from the PM8xx processor unit. • Replace the CI854/CI854A unit. F(ault) LED is ON Check that the CI854 board is in the process of being restarted. Allow time for this to finalize. Check that there is no configuration fault reported from CI854/CI854A in CBM. If the status remains initiate a reset signal (INIT) from the PM8xx processor unit. If the status still remains after the reset replace the CI854/CI854A unit. RxA LED is OFF No communication on Line A. • Check that slaves are configured and connected to this line. • If redundant slaves are used check that the redundancy is working properly. The backup slave has to answer to the life list requests sent by the master. • Check all cables and connectors for damage and loose or poor connections. Section 5 Maintenance PROFIBUS DP – CI854/CI854A 3BSE036351-510 A 215 RxB LED is OFF No communication on Line B. • Check that slaves are configured and connected to this line. • If redundant slaves are used check that the redundancy is working properly. The backup slave has to answer to the life list requests sent by the master. • Check all cables and connectors for damage and loose or poor connections. DUAL LED is OFF on both modules (CI854A only) The CI854A board is in the process of being restarted or configured. Allow time for this to finalize. Check that the redundancy for this module is set within CBM and the configuration is downloaded. CI854A supports hot swap. Table 34.

Repair as necessary R(un) LED is flashing Check that the relevant units are sending data. Check if the CI855 board is in the process of being restarted or configured. If so, allow time for this to finalize. If the condition persists: Halt the application program and initiate a restart. Replace the CI855 board. Tx1 LED is ON (not flashing) The unit is not transmitting data. • Check the CB for a failure message. Rx1 LED is ON (not flashing) The unit is not receiving data. • Check all cables and connections.
