Knowledge Base Articles

Modbus is one of the most common communications protocols for connecting Programmable Logic Controllers (PLCs) and other industrial data sources.

Open Automation Software Tags can be defined to connect directly to Modbus slave devices with the built in Modbus Driver Interface which supports communications over Ethernet and Serial interfaces with Modbus TCP, Modbus RTU, and Modbus ASCII protocols. From there, you can log any Tag item value from Open Automation Software to  Microsoft SQL Server.
