Measurement Timing

Introduction

If all event-related processes are disabled, cycle time for the TSX AEY 420 module is 1 ms. It is not affected by the number of inputs in use.

Measurements are chained in the following manner: channel 0, channel 1, channel 2 and channel 3.

The scan cycle is prolonged by 0.15 ms per channel if event-related processing is enabled.

Breakdown of Cycle Duration

The following table describes the various cycle times:

Configuration	Cycle Time
No event processing	1 ms
1 channel with event processing	1.15 ms
2 channels with event processing	1.30 ms
3 channels with event processing	1.45 ms
4 channels with event processing	1.60 ms
