So design, communication unit possesses RS485MODBUS and two kinds of agreement modes of TCPIP MODBUS, and the same operation of distal end protocol address is unanimous, sets up this temperature control parameter, address jointly through TCPIP agreement and RS485 agreement. Because of no 485 time delay, a TCPIP MODBUS protocol can be adopted to monitor and control a plurality of or hundreds of devices in real time, and an RS485MODBUS protocol can be adopted to monitor and control a small number of main control boards; the rest 485 channels can be used for carrying out online control on other equipment, and local remote control can be carried out through the dial switch, so that misoperation on the temperature controller cannot be carried out on the site.
In order to realize the current network communication mode indication, the onboard dial switch is connected with an LED indicating lamp.
Specifically, the near-end RS485 interface module and the far-end RS485 interface module both comprise an RS485 module and an RS485 interface, and the RS485 module adopts a 75LBC184 chip.
Specifically, the ethernet interface module includes an ethernet module and an ethernet interface, the ethernet module employs a CH395 chip, and the ethernet interface employs an SIP interface.
Specifically, the on-board dial switch adopts a DIP direct-insert flat-dial 2P 2.54mm dial switch.
The utility model relates to a two agreement network deployment communication temperature controller possesses RS485 ethernet two agreement communication networks, and can carry out local, long-range, local long-range bi-pass function through board-mounted dial switch and switch, and can carry out online control, and the wide use is supporting in current all kinds of temperature control equipment.
