Configurable Gateway - Ebyte NB114 User Manual

Chengdu Ebyte Electronic Technology Co., Ltd. NB114 User Manual

4.5.4.Configurable gateway

The gateway automatically polls the RTU device register according to the preconfigured
MODBUS instruction (only supports the configuration of MODBUS read instruction), and the
instruction in the non-storage table will directly operate the RTU device. The frequently read
instructions can be stored in the gateway in advance to shorten the response time (query the
configured instructions). Because of the above characteristics, the serial port side of the
configurable gateway can only connect to the Modbus slave station.
