Module Configuration, Output, and Input Data Chapter 4

Cyclic Rate Update Time (CtrnCyclicRateUpdateTime)

This value is used to set the cyclic rate update time for the CurrentRate

calculation. The value indicates the time in milliseconds from 1…32767. An

invalid number causes a configuration error. The default value is 10 for counters 0

and 1. The default value is 0 for counters 2 and 3.

See

Cyclic Rate Calculation Method (current rate) on page 32 for more

information on cyclic rate.

IMPORTANT

Do not change this value while the counter is enabled. Attempting to do

so will result in a BadModConfigUpdate error. See

page 120 for a list

of prohibited settings.

IMPORTANT

The Counter Scalar information does not apply to the L23E packaged

controller because rate measurement is not supported.
