TAC Xenta 700 version 5.1.1 and lower, Menta Delay block may not delay.

TAC Xenta 700 version 5.1.1 and lower, Menta Delay block may not delay.

Issue

Writing directly to a SR (set-reset) simple block in a Xenta 700 Menta application where that SR output is sent to a Delay block, the Delay block may not delay. The output on the Delay block will be set immediately, without any delays.

Environment

  • Xenta Servers version 5.1.1 and lower
  • Xenta 701, 711, 721, 731
  • Menta

Cause

This was a bug in version 5.1.1 and lower.

Resolution

Upgrading the Xenta Server to version 5.1.2 or later will resolve the issue.

If upgrading is not an option, this can be worked around by not writing to the SR block itself, but to a block in the logic before the SR block.
