Monitoring Features
3-5-1 Communication Unit's Status Flags
62
After network commissioning has been finished and there is communication
between the PROFINET IO Controller Unit and the GRT1-PNT, there are
multiple ways to monitor the status of the GRT1-PNT and its connected
SmartSlice I/O Units.
The monitoring status is available are displayed by the DTMs or can be
accessed from the IO Controller and used within the PLC program.
There are three types of monitoring information
• The Communication Unit's Status Flag as part of PROFINET IO Data
• The PROFINET IO Communication Status as indicated by the PROFINET
IO Controller
• The GRT1-PNT status information using the DTM
The Communication Unit's status or in short COM status flags are allocated as
the first word within the PROFINET IO Data with the PROFINET IO Controller.
These flags can be used to monitor the status of the connection between the
GRT1-PNT and the SmartSlice I/O Units as well as the status of the
SmartSlice I/O Units themselves. The table below defines the individual bits in
the Status word.
