By sending Explicit CIP messages to the Unit, the individual status information
of the SmartSlice I/O Units can be read. Please refer to Appendix C Explicit
messages.
The PROFINET IO Controller indicates the status of the PROFINET IO
Communication with the Unit. This also includes the PROFINET IO Alarms the
GRT1-PNT may send based on its state of the SmartSlice I/O Unit.
Appendix B PROFINET IO alarm messages describes the detailed information
about PROFINET IO Alarms. Please refer to the PROFINET IO Controller
manual (W12E) about details on accessing PROFINET IO Device status and
alarms.
The GRT1-PNT PROFINET IO Communication Unit's DTM provides multiple
features to monitor the detailed status of the Unit.
To use these features, the GRT1-PNT must be online, i.e. the DTM must
establish communication with the physical device. Switching to on-line must
be done via the FDT Container. To switch to online, perform the following steps
in CX-ConfiguratorFDT.
1 In the Network view, right-click the GRT1-PNT.
2 From the context menu, which pops up, select the option Go Online.
To access status information on the PROFINET IO and SmartSlice I/O
communication, again select the context menu, and select the Diagnosis
option.
Individual SmartSlice I/O Units can also be monitored through the PROFINET
IO connection. This data can be retrieved through the I/O Module tab and the
I/O Error History tab of the Diagnosis window.
Description
Indicates whether or not the automatic
parameter restoration to the SmartSlice
I/O Units was completed successfully.
This is the overall Unit status flag.
This flag will be ON if any of the other
flags (bits 0 to 13) is ON.
Indicates whether I/O data is being
exchanged normally.
