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 the 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 ILX56-PBS
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
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
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.
