[FONT="]Hi,
I'm having two Siemens S7200 PLCs ([/FONT][FONT="]CPU 224, CPU 226 (XM))[/FONT][FONT="] which are connected to two different HMIs (Simatic OP7) individually.
I want to take data from this existing system to a 3rd party system (h/w or s/w).
How to do it in cost effective way? And from below which is the best way
1)In the below link I thought of taking data directly from sensor, but didn't workout.

2) Taking from PLC
3) Taking from HMI
