Hi all, I have a question regarding the WorkingCounter. The WC actually shows me an error (incomplete) despite everything working fine. If I use one slave I get the following message in the kernel log: > [Thu Feb 23 10:32:17 2017] EtherCAT 0: Domain 0: Working counter changed to 2/3. Why 2/3? I have only one slave and even if the master itself is counted too, shouldn't it be 2/2?
If I add one more slave I get this message: [Thu Feb 23 10:34:54 2017] EtherCAT 0: Domain 0: Working counter changed to 4/6. This adds 3 to the nominal value and 2 to the actual counter. This leads to the questions: 1. Why is 3 the nominal counter value per slave? Shouldn't it be 1 count per slave when a EtherCAT frame passes by? 2. If the 3 is correct, what am I missing? I didn't loose any frames and communication works just fine (which is the reason why I never paid any attention to this odd value but I would like to use it for error handling).
