Memory Requirement of the Operating Hours Counter
The operating hours counter function block requires 36 bytes of memory plus
4 bytes per constant on the function block input.
Function of the Operating Hours Counter 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 counter is 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.
PUT, Send a Value onto the Network
The function block allows you to selectively send a 32-bit value onto the
network. The PUT function block provides data that another Pico-Link station
indicates it requires via the GET function block.

IMPORTANT
Operating mode change RUN, STOP, Voltage On, Off,
Delete program, Change program, Load new program. All
these actions do not delete the actual value of the operating
hours counter.
