Description
Input parameters
En
Enable parameter, see section Often used parameters
(Page 252).
Trigger
Digital input / output /
bit memory
STATUS_ERROR
Counter input
After the first edge change 0
→
1 and continuous value 1
of "Trigger" the block begins to count the operating time.
Reset
True / False
Digital input / output /
bit memory
STATUS_ERROR
Resets the counter to 0 or the Initial value on a positive
edge (0
→
1).
With the setting "True" the counter is continuously reset
and the output remains permanently set to 0.
With the setting "Input unused" or "False", the count is
not reset. If there is overflow (4294967295) the counter
starts again at zero or at the initial value.
Function parameters
Time base
100 ms
1 s
1 min
1 h
Time base of the uptime output by the block and of the
initial value.
Initial value
0 .. 4294967295
Start value
Retentivity
ON / OFF
If this option is enabled, the count value is saved in the
retentive memory. The last value therefore continues to
be used when the configuration is changed or a restart of
the module takes place.
If the option is disabled, the counter is reset to 0 or the
initial value when the configuration is changed or a re-
start of the module takes place.
For more information, refer to the section Often used
parameters (Page 252).

•
Configured as a
floating-point
number:
3.402823 e-38 ..
3.402823 e+38
•
Configured as a
counter: 0 ..
4294967295
Tag in which the totaled value of the operating time is
output. In the event of configuration as counter and over-
flow (4294967295), the counter starts again at zero.
