MODBUS Command Reference

n = 1 to 247 MODBUS ID, in decimal

a.a.a.a = 0.0.0.0 to 255.255.255.255 MODBUS slave gateway IP address, in decimal

p = 0 to 65535 Port that the slave gateway will be listening on, in decimal

Examples:

cmd modbusidmap 1 123.1.2.3 502 Set the MODBUS master gateway to forward messages for the

slave device with ID 1 to port 502 of the gateway at 123.1.2.3

cmd modbusidmap 1 0.0.0.0 Clear the MODBUS ID to gateway IP entry for slave ID 1

cmd modbusidmap 1 123.1.2.4 502 Change slave ID 1 entry to the gateway at 123.1.2.4

cmd modbusidmap 0 0.0.0.0 Clear all MODBUS ID to gateway IP entries

cmd modbusidmap Query all MODBUS ID to gateway IP entries

3.3 MODBUS Slave Gateway Command Reference

The following section provides commands used to configure the gateway as a MODBUS slave gateway.

For the following commands to be applied, the gateway must be configured for MODBUS mode using

cmd mode 6 and configured as a slave gateway using cmd modbusmode 0.

When the MODBUS slave gateway is enabled, the gateway will look at its MODBUS slave list to handle all

MODBUS functions and traffic. This MODBUS gateway is able to function as:

MODBUS TCP slave gateway

MODBUS Serial slave gateway

Self MODBUS device (one only allowed)

The MODBUS slave gateway will be using the default port of 502.

To add a MODBUS slave device entry to the MODBUS list. One entry is added at a time with a limit of up

to 247 entries (each entry requires a unique ID). MODBUS TCP slaves, serial slaves and self slave can be

added to the list. For the MODBUS self slave, the entry on the MODBUS list will be “Localhost, id”.

modbusadd (query MODBUS slave gateway list)

To display all the entries in the MODBUS list. Read only.

Example:

cmd modbusadd displays the MODBUS list

(192.168.1.20,247) TCP slave device with ID = 247

(Localhost,10) self slave device with ID = 10

(19200.N.8.1 A,155) serial slave device (baud 19200, no parity, 8 data, 1 stop, ASCII, no flow control)

with ID = 155

modbusadd id nnn.nnn.nnn.nnn (add a MODBUS TCP slave)

id = 1 to 247 MODBUS ID

nnn.nnn.nnn.nnn = 1.0.0.0 to 255.255.255.255 MODBUS slave IP address
