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
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.
