Multi-Slave
When this option is selected the user can select multiple nodes for the mapping
items in the Reactive Tag Map. This will allow the Modbus Router to emulate
multiple Modbus Node Addresses.
Node Address
The Modbus node address of the Modbus Router.
BAUD Rate
The BAUD rate will configure at what speed the data is send across the RS232
serial network. The module provides the following speeds:
1200, 2400, 4800, 9600, 19200, 38400, 57600, and 115200
Parity
The parity parameter will configure the parity of the module’s RS232 serial port.
The module allows for Even, Odd, or None parity setting.
Table 3.2 – Modbus configuration parameters
The Modbus Router can be configured to operate in one of two Base Address modes; Modbus
(Base 0) or PLC (Base 1). For example when operating in Base 0 mode the first holding register
address will be 40000 whilst in Base 1 mode the first holding register address will be 40001.
Depending on the system being interfaced to the user will need to select the correct option.
Failing to do this will result in the data being misaligned by one register.
The Modbus configuration is shown in the figure below. The Modbus configuration window
is opened by either double clicking on the module in the tree or right-clicking the module and
selecting
Configuration.
Once in the configuration window select the second tab at the top
