Greetings. I have a Wago 750-652 (RS232-485 module) connected in RS-485 to a vacuum pump using a custom protocol. The communication between the PLC and the pump is working, and I can send and receive messages from the pump with the i/o check tool of Wago. I want to make a program which is able to control the pump and retrieve some information of the pump such as temperature, speed, ... Nevertheless, I'm not sure about the implementation of this kind of program. Indeed, I have to send a lot of messages...
