ET200s IO's on CI854
I am triing to integrate an IM151 (ET200s) on a CI854 Profibus master.
I can read and write the to the IO modules. But if i disconnect any of the IO-Moules I get no error in the HW-tree, and the HWstatus is still ok.
Does anybody have experience with IM (ET200s) on 800xA systems?
Answers
Can't you use the ready made Object Types:
I would recommand to use watch dog heart bit between both communication, If the data doent receive by 800M controller, you generate an alarm and indication by logic..
A good practice to test connectivity is to connect an output to an input and measure the time it takes to trigger this.
Best Regards
