I have 02 I/O discrect tag and I want to define double indication with :

I always try to run away from scripts, for me is hard
you have two (A and B) imputs with 4 variable, if you create 3 tags [error(c), close(D), open(E))

tag C a==0 and b==0 or a==1 and b==1 .... is error
tag D a==1 and b==0 .... is close
tag E a==0 and b==1 .... is open

with this 3 tags that you create it is simple to send for event log with out any script
i test this in Cx-supervisor and it works

It's very simple. Just define another tag with Log Events (and alarm defined). Then trigger it for your '11' and '00' on a condition script.

A better way for me is to rework your PLC program (or something from where do you read) to use one Integer status tag with Hi and Lo alarms in it (with ot without logging as you wish). This's much more scalable (no need to add scripts for every valve or what are you controlling..)
