DuplicateDPStation
Indicates that the ILX56-PBS has detected another PROFIBUS DP station with
the same station address as itself and has entered a temporary Back-off mode.
1
– Duplicate detected (Back-off mode active).
0
– Normal (No duplicate detected).
NOTE
: In this condition the ILX56-PBS will not communicate on the
PROFIBUS DP network. Although the back-off time is
approximately 5 seconds, should the conflicting DP master remain
active on the PROFIBUS network, the ILX56-PBS will continuously
re-enter the back-off mode.
PROFIBUSFieldbusError
There is a PROFIBUS network issues (e.g. cable unplugged, under/over
terminated, etc.).
1
– Fieldbus error detected.
0
– Normal (No errors detected).
PROFIBUSDeviceError
At least one slave device has a communication issue (e.g. offline, not
exchanging process data, etc.)
1
– Device error detected.
0
– Normal (No errors detected).
PROFIBUSOffline
For ILX56-PBM only.
PROFIBUSStopped
For ILX56-PBM only.
PROFIBUSClear
For ILX56-PBM only.
PROFIBUSOperational
For ILX56-PBM only.
SlaveMode
This tag was designed for ILX56-PBM to decipher between ILX56-PBM in
master mode or slave mode.
1
– The ILX56-PBS will always have this bit on.
0
– The ILX56-PBS should
never
be in state where this bit is 0.
ControllerRun
The connected Logix controller is in RUN mode. 1
– RUN mode 0 –
PROGRAM / FAULT mode
ModuleRedundancyEnabled
For ILX56-PBM only (Currently not implemented)
ModuleRedundancyStatus
For ILX56-PBM only (Currently not implemented)
ConfigCRC
The signature of the configuration currently executing on the module.
ActiveNodeCount
The number of active and online PROFIBUS devices exchanging data with the
master.
SwitchOverTimeOut
For ILX56-PBM only (Currently not implemented)
DeviceLiveList
Indicates the nodes that are online on the local PROFIBUS network. Each bit
represents a node. When the specific bit is set ‘1’ then the device is online and
when the bit is off ‘0’ the device is not on the PROFIBUS network.
Bit 0
– Node 0 Online
Bit 1
– Node 1 Online
……….
Bit 126
– Node 126 Online
DeviceDataExchangeActive
Indicates the nodes that are online and exchanging DPV0 data on the local
PROFIBUS network. Each bit represents a node. When the specific bit is set
‘1’ then the device is online and exchanging data and when the bit is off ‘0’ the
device is not exchanging data on the PROFIBUS network.
Bit 0
– Node 0 Exchanging DPV0 Data
Bit 1
– Node 1 Exchanging DPV0 Data
