Summary

In this chapter, we will provide the steps to set up Control on your IG21 (automation via Structured Text / Ladder Logic).

For both the IG21 and IG41:

  1. We can read and manually write to registers to manipulate values on 3rd party PLCs

  2. Toggle digital outputs from our dashboards

  3. Set analog output values from our dashboards

In this section, we will go through how to make setpoint changes and toggle equipment on/off via automation for a pre-existing IG21 deployment.

Automation Control is currently not supported on the IG41.
