Operation of the function block
The relay is started via the trigger coil T…EN and can be
selectively reset via the reset coil T…RE. The third coil T..ST
terminates the run down of the actual time.
Variable time values
If you associate the function block inputs T ..I1 and T ..I2
with operands, you can use variable setpoints. The setpoints
are transferred as follows, depending on the time range
selected:
•
S
, value in milliseconds. The last digit is rounded up or
down to 0 or 5, maximum value = 999995 ms.
•
M:S
, value in seconds, maximum value = 5999 s.
•
H:M
, value in minutes, maximum value = 5999 min.
• Examples of time range
S
:
– Operand value 9504 -> Time value is 9.505 s.
– Operand value 45507 -> Time value is 45.51 s.
• Examples of time range
M:S
:
– Operand value 5999 -> Time value is 99 h, 59 min.
• Example of time range
H:M
:
– Operand value 5999 -> Time value is 99 h, 59 min.
Different methods are used depending on the operating
modes of the function block:
h
The delay times are the same as described for the
constants.
