The error flag will be set when one of the following conditions
occur:
If there is an ident mismatch during slave parameterization,
When receiving any form of FDL fault (data link layer fault). For
example: SAP Not Activated or Resource Not Available.
When the data size of the DPV0 data exchange does not match
what has been configured in the PLX50CU.
This Error flag is transient and will clear once a valid response is
received.
AlarmPending
Indicates the device has an alarm pending on the local
PROFIBUS
network. When the specific bit is set ‘1’ then the
device has an alarm pending that must be unloaded and when the
bit is off ‘0’ the device does not have an alarm pending.
0
– The node has no alarm pending
1
– The node has an alarm pending
DiagnosticsPending
Indicates the device has diagnostics pending on the local
PROFIBUS
network. When the specific bit is set ‘1’ then the
device has diagnostics pending that must be unloaded and when
th
e bit is off ‘0’ the device does not have any diagnostics pending.
0
– The node has no diagnostics pending
1
– The node has diagnostics pending
OutputAssemblyNodeAddrMismatch
This bit indicates that there is a mismatch between the actual
device station address and the expected Logix mapping station
address.
0
– Station address matches
1
– Station address mismatch
MappingCRCMismatch
If there is a mismatch in the mapping between Logix and the
PLX51-PBM it can result in data appearing in the incorrect
location which means the user can be sending incorrect data to a
device which can have unpredicted results.
0
– The mapping for the output data is correct
1
– There is a mapping mismatch in the output data
SlaveClearOpMode
When the PLX51-PBM is in
Slave Mode
; this will indicate that the
respective slave is in fieldbus CLEAR mode (received from the
DP Master on the network).
0
– Slave Station is in CLEAR fieldbus mode
1
– Slave Station is
not
in CLEAR fieldbus mode
SlaveAlarmAck
When the PLX51-PBM is in
Slave Mode
; this will indicate that the
respective emulated slave has received an acknowledgement for
the pending alarm.
0
– Slave Station has received an Alarm Acknowledgement for
last pending alarm
1
– No Alarm Acknowledgement have been received for a
pending alarm or there is no alarm pending
StationNumber
The station number of the specific slave device.
DeviceMappingCRC
The checksum of the Mapping for the specific slave device.
DeviceSpecificInputDataFields
The tags created for the input data will be slave specific.

Description
Control
StationNumber
The station number entered by the Logix mapping code of the
specific slave device.
AlarmTrigger
N/A. Slave Mode Only.
DeviceMappingCRC
The checksum of the mapping that was applied by the generated
Logix code used to verify if the mapping being used is valid.
DeviceSpecificOutputDataFields
The tags created for the output data will be slave specific.
