The Get button reads the current master table in the Gateway. The Send button sends the user defined table to the Gateway. The Clear
button sets all master fields in the User Configuration Tool to zero. Clicking the Clear button does not affect the table entries stored in the
Gateway.
Master Table
Map Number. There are 32 possible table entries in the master table. The map number is only an index into the master table.
Local Register. Setting the local register defines the Modbus register within the Gateway master device and wireless system.
Action. Select an action to define the operation to be performed between the registers of the master device and the slave device. Select-
ing Read From sets the master device to read the remote slave register and copies the result into the local register. Selecting Write To
writes the local register contents to the remote slave register. Select None if this table entry is empty.
Remote Type. Selecting the remote type defines the data type (bit or 2-byte word) in the remote slave device. Different data types use
different commands to access the data in the slave device. The DX80 devices always use holding registers. The master device can read
the remote slave data in bit or 2-byte registers format.
Remote Register. Setting the remote register number defines the slave device register to read/write.
Slave ID. Use the slave ID field to select the unique Modbus slave ID number used for each slave. DX80 devices can have a Slave ID
from 1 to 247.
Poll Timeout (ms). The poll timeout value defines how long the master waits for a slave response when performing that map action. If
the slave device’s response is not received within the timeout period, the master device continues to the next table entry.
Master and Slave Mode Switches
The DX80 Gateway can operate in two distinct modes: master mode or slave mode. In master mode the Gateway can read/write register
data from other Modbus slave devices. In slave mode the Gateway responds to a Modbus master request for data. The factory default
sets the DX80 Gateway to slave mode.
To change the Gateway to a master device:
1. Fill out master table with at least one entry.
