HI everyone,


I have Codesys 2.3 SoftWare and PLC Wago 750-891.


I want to control the speed of the motor. It can be controlled by string commands. Its work is the USB serial interface protocol. So I am using raspberry pi. motor have usb port conected with usb port on raspberry pi.


1. PC---PLC (750-891) ---rj45----raspberry pi--usb 2.0 cable -- motor.


and I want to use the Modbus protocol for the PLC (Master) and Raspberry Pi (Slave). Is it possible that the whole process can work on PLC? If yes, then how? can i write a data from PLC and then proceed with raspberry and control motor?


how to interface with PLC and raspberry pi which libray in codesys 2.0?
 
But Shiv has already recognized that a device in between with a USB host is easier.
However, you can do without the Wago controller if Raspberry is already in the game.

Zum Vergrößern anklicken....
but I want to do all procedures with PLC. If I choose a PLC for my hardware that works on the USB protocol without a Raspberry Pi, it will be more expensive for the single motor. all over motive is less expensive and control By PLC. whatever I will add after the PLC, like any controller that works on USB protocol. It will be less expensive.
