Tag
Description
Control
StationNumber
The station number entered by the Logix mapping code of the
specific slave device.
AlarmTrigger
When this bit is transitioned from 0 to 1 it will trigger an alarm
notification to the DP Master.
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.
DPV1 Class 1 Messaging (MS1)
The PLX51-PBM supports DPV1 Class 1 (MS1) messaging when operating as a
PROFIBUS Slave. See the DPV1 Objects in the PLX50 Configuration Utility device
configuration section for more information regarding the configuration of the DPV1
Objects. The user can configure several slot and index combinations for DPV1 Class
1 communication (for each added PROFIBUS Slave device).
When the PROFIBUS Master sends a DPV1 read/write command for the configured
slot and index, the PLX51-PBM will access the configured Logix tag to provide the
required data. The data that will be written or read will be extracted from the Logix
SINT array configured in the DPV1 objects of the device configuration window. Below
is an example of the DPV1 operation when the PLX51-PBM has been configured as
a PROFIBUS Slave.
