DuplicateDPStation
Indicates that the PLX51-PBM 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 PLX51-PBM 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 PLX51-PBM
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
The PROFIBUS network is offline and the PLX51-PBM will not
communicate on the network.
1
– PROFIBUS fieldbus state is OFFLINE.
0
– PROFIBUS fieldbus state is
not
OFFLINE.
PROFIBUSStopped
The PROFIBUS network is running and the PLX51-PBM is
communicating on the network, but it will not exchange any process
data with any slave device.
1
– PROFIBUS fieldbus state is STOPPED.
0
– PROFIBUS fieldbus state is
not
STOPPED.
PROFIBUSClear
The PROFIBUS network is running and the PLX51-PBM is
communicating with all slave devices on the network, and if
configured in the PLX51-PBM, the module will configure and
exchange process data with each slave device.
NOTE: In CLEAR mode the PLX51-PBM will not send any output data to any slave
device.
1
– PROFIBUS fieldbus state is CLEAR.
0
– PROFIBUS fieldbus state is
not
CLEAR.
PROFIBUSOperational
The PROFIBUS network is running and the PLX51-PBM is
communicating with all slave devices on the network, and if
configured in the PLX51-PBM, the module will configure and
exchange process data with each slave device.
1
– PROFIBUS fieldbus state is OPERATE.
0
– PROFIBUS fieldbus state is
not
OPERATE.
SlaveMode
When in Slave mode the PLX51-PBM will emulate multiple
PROFIBUS Slave devices. This indicates when the PLX51-PBM is
in Slave mode.
1
– The PLX51-PBM is in Slave Mode.
0
– The PLX51-PBM is
not
in Slave Mode.
ConfigCRC
The signature of the configuration currently executing on the
module.
DeviceListList
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
