Example: Digital input – double-point information, counter value
Update Counter Value
Counter values (TI 37) are not transmitted by the I/O Master Module upon each change, but
by means of a corresponding counter interrogation. With that, the displayed process value can
be also updated.
If a counter value is assigned on the selected DI module, then a button appears below the sta-
tus area.
•
In order to initiate the counter interrogation, click on the button
•
Select in the dialog the parameterized counter group (or all groups)
•
Select the desired action:
─
Example: “Freeze and transmit”, if you want to update the status display
─
Example: “Freeze with reset and transmit”, if you want to set the value to 0 and update
the status display
•
After that, click on the button
•
Click on the button in order to close the dialog
The updated process value of the requested group is now displayed.
Note
The counter group and action correspond to the identifiers
FRZ
and
RQT
in the message to the I/O Master
Module.
