Corrected from:
IO-1000 EtherCAT Buskoppler EPM-S131 (from 1A.40; 13587423)
Behaviour of new version:
Error no longer detectable.
What happens?
The MF LEDs of the I/O compound modules, connected to the I/O 1000 EtherCAT bus coupler module are permanently red.
The controller logbook indicates the following error message for the bus coupler:
"EPM_S130 (1009): Slave init command WKC error - command: FPWR"
The EtherCAT master cancels the initialisation phase with the following error message:
"Up-download manager is stopped because of error"
The EtherCAT bus does not change to Operational.
When does this behaviour occur?
If an I/O 1000 bus coupler module is connected to the EtherCAT of the Lenze controller, the above-described behaviour may sporadically occur when the device is switched on.
Which products are concerned?
L-force controller 3200 C from V3.6
L-force controller p500 from V3.6
EPM-S130 (I/O 1000 EtherCAT bus coupler module)
Short-term measures:
Switch the mains for the I/O 1000 EtherCAT bus coupler module.
Then, restart the Lenze controller.
Evaluation/recommendations:
When switching on a system with Lenze controllers and I/O 1000 EtherCAT bus coupler, the EtherCAT sporadically does not change to Operational. Process data cannot be exchanged between controller and EtherCAT nodes.
