SMI2 first start (video tutorial)

This is the second video from our video tutorial series.

This video shows how easy is to establish communication between the SMI2 digital display and our PR200 programmable relay using the Modbus RTU protocol.

First we configure the display SMI2 with the "SMI2 Configurator", then we connect it to the relay PR200 via the RS485 interface. In a simple project with the software tool "akYtec ALP" we create a variable and transfer it to the PR200. As a result, the value of the variable is displayed on the screen.
