Configuration of the mirroring back for output events (object groups 11 and 42)
You first create the data point types Binary Output Event (object group 11) and Analog
Output Event (object group 42) as described above as data points of the object groups 12 or
41.
The local values of these two object groups can be monitored for change and the changes
transferred to the master (). Changing a local value can, for example, be caused by manual
operator input on site.
To allow the value resulting from local events or interventions to be transferred to the master,
the data point in question requires a channel for mirroring back. You configure this mirroring
back function is configured using the "Value monitoring" option in data point configuration,
General tab.
Remember that to use the mirror back function, you need to interconnect the local values in
the controller with the relevant PLC tag of the data point.
Format of the time stamp
Time stamps are transferred in UTC format (48 bits) and contain milliseconds.
