SAFEX-C1x with Elmo Platinum Harmonica Drive FSoE

[ctrlXProgrammatore]

Is the Elmo Platinum Harmonica drive with FSoE supported by SAFEX-C12? If so, do you have an example you can send me?

I have CORE, SAFEX-C12, and Elmo Platinum Harmonica Drive. I am trying to establish FSoE communication but can't get FSoE to connect. The standard EtherCAT communication is working.

The problem seems to be with the Parameter CRC as part of the Elmo Drive properties in SAFETY Engineering. The Safe Params CRC from the drive was entered into the properties in SAFETY Engineering:

The connections have been assigned in IO Engineering:

When looking in the FSoE connection properties in the PLC it seemed like the CRC was not being transmitted. The FSoE_SafetyMasterMessage_04_Bytes_Out.FSoE_MasterCRC_0 & FSoE_SafetyMasterMessage_04_Bytes_Out.FSoE_MasterCRC_1 had values of 0 even when the Always Update Variables was changed to “Enabled 1 (use bus cycle task if not used in any task)”. This is also indicated by the diagnostic in the drive:

As a workaround test the Params CRC value was added to a POU but it did not help:

Thank you.

As I have seen a similar case once, please check the startup parameter in ctrlX IO Engineering if your settings done by hand (and resulting in a CRC) are overwritten by switching the fieldbus up. Then the CRC could have changed.

In my known case it seemed that in the device description file of the ELMO drive some parameter were fix set to a value and customer wanted to change it with the configuration tool but was overwritten again.
