Explicit Messaging Utility
For PLX51-PBM Master mode only, the PLX50 Configuration Utility provides a utility
to initiate explicit messages to the PROFIBUS devices. The messaging options
include the following:
DPV1 Class 1 Read
DPV1 Class 1 Write
DPV1 Class 2 Read
DPV1 Class 2 Write
Read Diagnostics
Read Alarms
To open this utility, right-click on a PROFIBUS device and select the
Explicit
Messaging
option.

– Explicit Messaging Option
Use the
Action
combo-box to select the type of explicit message. Depending on the
type selected, various other parameter controls will become available. Once the
correct parameters have been entered select the
Execute
button to initiate the
explicit exchange.
NOTE: For Class 2 messages, if a class 2 connection has not already been established, then a Class 2
Initialization message will first be sent. The class 2 connection will then remain open until either the
station address is changed, the manual Abort button is selected, or the utility is closed.
