The function block input I1 can be assigned the following operands:
•
Constant.
•
Markers MD, MW, MB.
•
Analog inputs IA01 to IA04:
•
IA01: Terminal I7.
•
IA02: Terminal I8.
•
IA03: Terminal I11.
•
IA04: Terminal I12.
•
Analog output QA01.
•
Output
…
QV> of a different function block.
Output
The output QV supplies the counted operating hours as an integer value in
hours.
You can assign the following operands to output
…
QV:
•
Analog output QA01
•
Markers MD, MW, MB
Function of the function block
If the enable coil OT…EN is triggered to the 1 state, the counter adds the
value 1 to its actual value every minute (basic clock rate: 1 minute).
If the actual value on QV reaches the setpoint value of I1, the contact
OT…Q1 switches for as long as the actual value is greater than or equal to
the setpoint value.
The actual value is retained in the unit until the reset coil OT…RE is actuated.
The actual value is then set to zero.
Accuracy
The operating hours counters are accurate to the nearest minute. If the
enable coil signal is terminated within a minute, the value for seconds is lost.
The value range of the operating hours counter is between 0 hours and
100 years.

The following operations do not clear the actual value of the
hours-run counter: Operating mode change RUN, STOP, voltage
ON, OFF, Delete program, Change program, Load new
program.
