GW-7553-B / GW-7553-M PROFIBUS/Modbus TCP Gateway User Manual
(Version 1.35, May/2017)
PAGE: 16
The DIP switch is used to set the GW-7553-B module works in operation mode or
setting mode. In the normal situation, it needs to set the DIP switch to the “Normal”
position. In this case, the GW-7553-B module can communicate with Modbus devices.
When the user sets the DIP switch to the “Setting” position, the GW-7553-B module
can communicate with the utility to set the safe value and network configuration.
GW-7553-M module only can connect to Utility via setting the control bit (please
refer section 4.6.2 Output data area and communication command) to enable the
setting mode of the GW-7553-M.

The user can change the position of the DIP switch or set the control bit (please refer
section 4.6.2 Output data area and communication command) to enable the setting
mode of the GW-7553-B, as shown in
