Answer question

Profibus Slave: Communitcation Error?

Hi folks,

I'd integrated a Profibus valve in Control Builder M (CBM Professional, Version 5.1.0/1), converting .gsd file in .hwd element.
After download, I don't have any warning or error on CI854 or slave instance being showed in CBM.
In graphic displays, I can operate this valve normally (System 800xA version 5.1.0/REV A).

My doubt is: always that I operate this valve, there're error messages on CI854 hardware event list in 800xA (attached) and in controller log (attached):

E 2018-10-01 18:46:10.839 On Unit= 1.2 HWError N170 0000 See HWTree Error 16#00000001 16#00000000 E 2018-10-01 18:46:10.839 On Unit= 1.2.0 HWError N170 0000 See HWTree Error 16#00000001 16#00000000 E 2018-10-01 18:46:10.840 On Unit= 1.2 HWError N170 0000 See HWTree Error 16#00020001 16#00000008

Are there any Profibus communication problem with my network? The controller and CIs remains in fault state and then normalize by themselves once/twice a month - this behavior is under investigation. Is there any correlation?

Thank you for attention.
