This will open the MS/TP Check screen as shown below .
Press the Retrieve Parameters button which should display 340MB
transmitter object data as shown below .
The LED located next to the 340MB network port, labeled “Comm
LED”, will flash once to visually confirm communication between
the 340MB transmitter and Modbus master controller .
Use the scroll bar to view all object data .
If the 340MB transmitter fails to communicate with the Modbus
master controller, check that the correct polling address was
entered in step 12 found on page 8, the integrity of the network
port connection and, if necessary, settings in the Modbus master
controller .
Press the Close button to return to the Main Screen .

The following Register Map is provided to assist in the program-
ming of the Modbus network .

MOdEL 340MB FACTOrY dEFAuLT SETTINGS
The table below is a list of factory default setting for all 340MB
variables . These settings can be changed by accessing the pa-
rameters sensor (page 7) or Configure MS/TP screen (page 8)
to best fit your application . As new valves are assigned, they can
be written in the blank provided next to each variable for future
reference .
