Hey,
I'm currently working on the assembly and programming of an automated reaction vessel. For this vessel I am using an excisting brabender Loss-in-weight feeder with congrav S cotroller. this is used for dosing the Desmodur 15 powder i need.
My problem is the next:
I'm using a CPU313C 2DP PLC from siemens with a CP341 module with MODBUS driver. I learned some S7 programming at school but I have no idea on how to begin on this problem.
i need to be able to change the setpoint in the congrav s module, start and stop the weighing through the MODBUS interface.
here is all the information I have:
the weigher:

the congrav S module:

tnx
