Hello,
I’m working on a custom c++ application to run on an EPC1522 edge device.
This application will have to read & write digital I/O on a I/O module connected via a AXL F BK PN TPS bus coupler.
Can you make recommendations about which communication technology and protocol to use to facilitate communication between the edge device and the I/O?
I’m lost in the plethora of different protocols (OPC, Profinet, Rest, Grpc, …) and looking for advise and pro’s and con’s.
thank you!
Any ideas on the amount of data you want to exchange? And how often?
For this project the I/O communication will be limited: continuously reading 1 digital + 2 analog inputs @ +/- 20 Hz, writing 3 digital outputs every few seconds and 1 relay 15 Hz.
