Before any dashboard can show a tank level, a sensor has to tell a PLC, and the PLC has to tell the SCADA server. That conversation happens over industrial protocols — Modbus, RS-485, EtherNet/IP, PROFINET — the plumbing of every automated plant.

Tell us what you are trying to automate — we will point you in the right direction.
