Post by albzen on EtherCat Slaves diagnosis ^{CODESYS Forge talk (Post)}
Hello everybody, I'm working on a RunTime Plc (Codesys 3.5.16/18.20) connected to an EtherCat bus with many devices. The bus has some communication fault but I don't know how understand which is the device or the cable that has the trouble. To understand the cause of the problem I would like to read the WKC (Working counter) of the devices (0x0300...0x030C), how is explained in EtherCat documents, but it seems that the read of the counter is disabled. Attached there is an extract of the Ethercat document. Can anyone give me some advice about how and with function can I read it. Thank you in advance!

check on EthercatMaster status page if you loose Ethercat frames - and check how the jitter is on Ethercat Master task

Hi, a few suggestions on how to tackle the problem: - it might help to increase the cycle time of the ethercat task - increase the value of the ethercat parameter DCInSyncWindow (https://content.helpme-codesys.com/en/libs/IODrvEtherCATDriver/Current/pou-IoDrvEtherCAT/DCInSyncWindow.html) (see attached image) - enable FrameAtTaskStart (https://content.helpme-codesys.com/en/libs/IODrvEtherCATDriver/Current/pou-IoDrvEtherCAT/FrameAtTaskStart.html) in the ethercat master (see attached image) - if the drives can handle the synchronization problems, checking of the synchronization can be deactivated using SMC_Set_ETC_DCSyncSupervision (https://content.helpme-codesys.com/en/libs/SM3_Drive_ETC/Current/SMC_Set_ETC_DCSyncSupervision.html).

BTW - I had a chat with a Beckhoff support engineer. He explained that if you use sync0 and sync1, two frames per cycle are expected.
