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.
Up Counter:
Whenever a prescribed clock transition occurs with-
out an error on Source B the count will increment by
+1. If the count is equal to 9,999 when the transition
occurs count will be 1 after transition.
Down Counter:
Whenever a prescribed clock transition occurs with-
out an error on Source B 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 follow-
ing:
None, Open, Shorted, Measurement Error, Bad Cal
Data, Ambient Error, RTD Error, Fail, Math Error,
Not Sourced, Stale
