7-8 Using The Sequence of Events Module in FIFO Mode

Use the Configuration tab in RSLogix 5000 to enable Latch CST, as

shown in the example below.

IMPORTANT

We suggest you monitor the I.EventOverflow bits to

make sure you are aware of when transitions were

either not timestamped or when timestamp data was

overwritten.

Click on this box to enable

the Latch CST feature.

Clear the box to disable

the feature.
