Hello Everybody, I have a problem, I need to observe status of PLC and have a OP17connectedtoPLC (CPU 103, one port) at the same time, is that possible?, and what do I need ?.

Thanks for your answers, and Sorry for mi english

Dear HorusH

OP15 used to have a Loop through Mode where you culd access the CPU
from IF1 of OP while PLC was connected to IF2 of OP15.

I think there is similar facility in OP17 also. Please see attached extract from
OP15 manual.

This only saves you the trouble of removing the OP - PLC connector.
If you start "Status Variable" or " Program Status" in Loop Through Mode
the OP screens do not get updated.

Hope this helps
