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