There are 3 PLCs (Siemens S7) and a Factorylink visualisation PC in a plan.
We have to change the PLC program in a plc. We have the source of old PLC program, but nothing about FACTORYLINK link. The communication between the PLCs and PC is a S7 H1 communication, what implements a deltalink SINEC H1 driver. In the PLC there are some FB for communication, but we don't know the description of its interface. Have somebody a manual for DELTALINK SINEC H1 driver, or FL_READ, FL_WRITE, FL_ENCODE FBs? How does Factorylink communication work?
Thanx!
