4.3
Counter Input
CI_PULSE
(SIMATIC Manager hardware catalog)
Parameters for counting floating pulses.
The counter value is provided as a process value.
4.3.1
Contact
Defines the contact type.
Possible values
Description
Mechanical Contact Mechanical contact
Electrical Contact
Electrical contact
The counter rises in increments when the contact closes (
0
R
R
).
The debounce time for the signal type [Contact_Mech] is long, but short for
[Contact_El].
Note the following: a short debounce time allows higher signal frequencies that
can be counted, but at the same time demands greater signal quality of the
contact.
Reference values
for sampling rates of 1 (50 %).

4.3.2
New CI Value
New counter value that is set by the controller during the connection setup phase
of the Profinet communication.
The existing counter value is replaced by the new counter value if the function
output byte value changes from 0 to 1.

4.3.3
Power-up Mode
Parameters for defining the behavior of [PowerUpMode].
The operation of the counter after powering up the I/O module can be configured in
two possible modes with the [PowerUpMode] parameter:
Normal mode (RESET)
Safe mode (LASTVALUE)
After powering up the I/O module, the counter is reset to "0" (default value) – the
counter value does not have to be permanently saved in the I/O module.
The controller is responsible for the following:
for tracing the current counter
and
for persistent saving in the event of power failure.
