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 on
the EZ-NET that another station indicates it requires via the
GET function block.

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.
