Serial communication between CP341 and CP525-2 (S5).
It works but not like it should. Sometimes verry slow. Think I use Siemens blocks in the wrong way but I can't find a solution in the manuals.
I use FB8 (P_SND_RK, parameter SF set to 'S') to send data and
FB8 (P_SND_RK, parameter SF set to 'F') to receive data.
Both work independantly from each other.
Siemens manuals say you should use FB8 only once but when switching parameters the communication just stops.
They also say use FB7 (P_RCV_RK) but this makes no difference.
Anyone uses this before?
