ACS 550 modbus communication
I have 8 ACS 550 drives of different power rating which has inbuilt embedded Modbus communication protocol.
I need to use this to communicate with my central control station which has Allen bradley L30ER Compact Logix controller.
What is the hardware required to achieve this communication as it will eliminate lot of hardwiring for me.
Thanks in advance.
If you mean ModBus RTU, to communicate with ACS550 no more hardware is required, the drive have embedded the com port ModBus RTU.
You need to define the parameters and the settings in the drive to activate the ModBus comm:
98.02 --> Modbus std
10.01 --> COMM
10.02 --> COMM
11.02 --> COMM
11.03 --> COMM
The appropriate section in ACS550 manual then gives you the other details to complete the set up.
Make sure that the FW version of the drives have the same number, to avoid malfunctioning in the communication, parameter 33.01

Hope this help you
