PROFIBUS issue

Hello!

I am working on a self-proof project. I configured the PROFIBUS COUPLER with I/O module (32bytes) and start running "online". The Q166.0 (in slave 2) sends out alternative signal while I166.0 (in slave_1) should receive the alternated signal. But I166.0 value is "1" all the time. Other signals works correctly. Please see the attachements.

At first, I thought the problem was caused by address overlapping. I changed the I/O module address in the module but the problem remained.

Do someone encounter the same problem before? I am confused...

Hope to hear from you soon.

Best regards,

ZhZL
