Counter Function
Function counts up or down from Load Value and produces
Output Value = On when Count = Target Value.
Note:
Count value clears on power loss.
Load Value restored on power up.
Counter Operation:
Whenever a prescribed clock transition occurs with-
out an error on source B the count will be equal to
the Load Value.
If Function is an Up Counter:
Whenever a prescribed clock transition occurs with-
out an error on Source A the count will increment by
+1. If the count is equal to 9,999 when the transition
occurs count will be 1 after transition.
If Function is a Down Counter:
Whenever a prescribed clock transition occurs with-
out an error on Source A the count will decrement by
-1. If the count is equal to 0 when the transition oc-
curs the count will be 9,999 after transition.
An error, when read, can indicate any of the following:
None, Open, Shorted, Measurement Error, Bad Cal Data,
Ambient Error, RTD Error, Fail, Math Error, Not Sourced,
