MODBUS Configuration Commands

to maintain backward compatibility with CTM13x modems

configured as MODBUS gateways

cmd modbusmode 1 Set gateway to be a MODBUS serial RTU master gateway

cmd port 1 9600 8 n 1 0 Set primary serial port as MODBUS serial master with baud rate

of 9600bps, 8 data bits, no parity, 1 stop bit and no flow control

cmd modbusidmap 1 123.2.1.2 502 Add an entry to the MODBUS ID to slave gateway IP map.

Repeat this command for MODBUS IDs = 2 to 247.

cmd modbusidmap List all entries in MODBUS ID to slave gateway IP map

cmd mode 6 Set the gateway to auto connect to both the wireless network

and the MODBUS host interface

cmd save Save the gateway configuration to non-volatile memory

cmd pwr mode 2 Power cycle the gateway for the configuration to take effect

2.2 MODBUS Slave Gateway Configuration

The following set of gateway commands will configure the gateway to act as a MODBUS slave gateway

using MODBUS RTU between the gateway and the MODBUS serial slave devices, and using MODBUS RTU

over UDP over-the-air.

cmd factory Reset gateway configuration to factory defaults

cmd modbusctm130 1 Set gateway to use MODBUS RTU over UDP over-the-air

to maintain backward compatibility with SCADA master devices

that polled CTM13x modems configured as MODBUS slave

gateways

cmd modbusmode 0 Set gateway to be a MODBUS slave gateway

cmd modbusdel 0 Delete all previously configured entries of MODBUS slave IDs

cmd port 1 9600 8 n 1 0 Set primary serial port as MODBUS serial slave device with baud

rate of 9600bps, 8 data bits, no parity, 1 stop bit and no flow

control

cmd modbusadd 1 Serial R Set the serial port slave device to have a slave ID of 1 and to use

MODBUS RTU as the serial transmission mode.
