Is there System Word that provides the OS version of a Unity CPU ?

Published date: 04 January 2019

Issue
Customer would like to display the existing CPU firmware version on his HMI/SCADA.

Product line
Control Expert, Unity Pro, M340, M580, Quantum, Momentum, Premium, Atrium

Resolution
System Word %SW14 will provide the Unity user with the OS version currently running in the Unity CPU.
The value that you read is in decimal. Please convert it to hex in order to see the version number.

Using an M340 with OS version 2.50 as an example we might see a decimal value of 592 in %SW14.
When converted to hex we see a value of 250, or version 2.50.
