Cycle time of the Xenta 121

Issue

What is the cycle time of the Xenta 121 and can the Hardwired In/Out setting be used to provide quick pass through signals.

Product Line

TAC Vista

Environment

Xenta 121 FC/HP

Cause

The Xenta 121 takes 2.1 seconds on average to process the entire program between monitoring the inputs. This makes it unsuitable for applications that require detection of quick transitions such as a momentary push button in a lighting application.

Resolution

Avoid the use of a momentary push button and configure the Hardwired Output to follow the state of the Input. The Output will trigger up to 2.1 seconds after triggering the push button.
