Compatibility of HMI and Controller Versions

Overview

When building a solution with some HMI and controllers communicating to each other, you must use controllers and HMI devices at the same firmware / runtime compatibility level.

When you download an application with an HMI from EcoStruxure Machine Expert, the HMI runtime is automatically updated to the latest version.

NOTICE
	COMMUNICATION INTERRUPTION Do not use a different controller firmware version or a different HMI runtime other than that which is delivered with the Vijeo-Designer version specified in the Release Notes for the given EcoStruxure Machine Expert version. Failure to follow these instructions can result in equipment damage.

Refer to the EcoStruxure Machine Expert Release Notes for the relation between the EcoStruxure Machine Expert version, the controller firmware, and Vijeo-Designer.
