Processing details
■Input condition
When the input variable RUN is TRUE, this function block performs integration processing to the input (CIN) and outputs the
result.
When the input variable HOLD is TRUE, this function block holds integration processing to the input (CIN).
When the input variable STPRS is TRUE, this function block stops integration processing and resets the integrated value.
When the input variable RS_START is TRUE, this function block resets integration processing and then restarts the
integration processing.
■Input value increment operation
The following processing is performed for the input value (CIN).
Integration start signal (RUN)
FALSE
FALSE
TRUE
TRUE
CIN: Count value, CIN

Recommended range
TRUE: Execute
FALSE: Stop
TRUE: Execute
FALSE: Stop
TRUE: Execute
FALSE: Stop
TRUE: Execute
FALSE: Stop
Ring counter with the range of -
2147483648 to 2147483647
(Pulse increment for each execution
should be 32767 or less.)
0 to HILMT
0 to 999
Recommended range
1 to 999
1, 10, 100, 1000
1 to 2147483647
0: When an integrated value
exceeds the integration high limit,
the value is cleared to 0.
1: When an integrated value
exceeds the integration high limit,
the high limit value is held.
