Zenon 15 - Command Sequencer triggers undesired ALC interlockings

Zenon 15 - Command Sequencer triggers undesired ALC interlockings

Description

The Command Sequencer triggered randomly undesired ALC interlockings.
The issue has been addressed and the behavior is now as expected. It is guaranteed that when interlocking is started, at least one complete ALC calculation cycle (incl. taking over current variable values) is done.

To benefit from this fix:
  • Update your zenon Software Platform to the latest build of zenon 15 or higher.
