Topic: Need help reading registers in Arduino from PLC (Read 44 times) previous topic - next topic


Hello. I am using an Allen Bradley L61 Control Logix (5535) PLC interfacing with an Arduino with a humidity sensor. Hopefully someone on here has familiarity with Logix Designer for the AB series PLC as I am looking to use a message instruction over Ethernet/IP (CIP Based) to read from a a specific register in the Arduino for relative humidity from said sensor in whatever data type that i can.

From searching around I am not sure if there is a library existing for AB controllers, as I have seen them for other controllers such as Siemens? Or Setting up socket communications between the two devices over ethernet. Or is there a way to run an OPC Server on the arduino to interface and write data into a tag in the PLC?
