Function description:
Through WIFI (ModBus TCP protocol) and 485 (Modbus RTU protocol) control of 8 relays, support 1-255 seconds delay, click, 8 local buttons can be configured to self-lock, follow, click or digital acquisition mode. Provides the Modbus TCP/RTU gateway function, and the 485 interface can be cascaded to other ModBus RTU modules. The module supports ModBus TCP 01, 02, 03, 05, 06, 15 and 16 commands, and can flexibly select different commands to access the status of relays and inputs. In cascading mode, the module supports ModBus TCP/RTU protocol conversion and transparent transmission from WIFI to 485 interface. The WIFI configuration tool can be used to modify the module address, WIFI network and other parameters, and the jumper can be used to lock the module configuration to prevent mismatching, with the configuration tool source code (implemented via DLL calls). Free WIFI relay module +485 relay module centralized control software. Support cloud remote control, wechat control please pay attention to the public number "cloud remote control".
The SR-311-WIFI module is cascelled to two SR-311-E8B modules. The ModBus RTU protocol is used on the 485 interface.
