add HMI to already operated PLC system

Post by karimaliali49 » Thu Oct 08, 2020 1:00 pm

Hello All !

we have in our plant an already operating system using CPU s7 314 connected to OP7 operating panel. i do not have the original code of the PLC.

what i want to do? is to add a new HMI TP277 to this system in addition to the OP7.

my question, is it possible? especially i will make few changes in the PLC code and when i uploaded the PLC program i did not found OP7 connected in the connection section.

the software i'm using is simatic manager V5.5 for PLC, and WINCC flexible 2008 sp3 for HMI.
