4. Communication Function Instruction

 

The controller provides serial asynchronous half duplex RS485 or RS232 communication port, and uses MODBUS-RTU protocol. All types of data information can be transmitted through the communication line. Multiple network controllers can be simultaneously connected on one line. Communication address no. for each network controller can be set. The communication connection should use shielded twisted pair with copper mesh, and the wire diameter should not be smaller than 0.5mm2. For wiring, the communication line should be far away from strong electricity cables or other strong electric field environment. It is recommended to use T type network connection mode, and not to use star connection or other connection modes.

 

MODBUS_RTU communication protocol: MODBUS protocol adopts the communication connection mode of master slave response on one communication line. Firstly, signal of the master computer addresses one terminal equipment (slave equipment) with unique address; Then the response signal sent by the terminal equipment is transmitted to the master computer in opposite direction. In other words, on only one communication line, signal transmits all communication data flow along with two opposite directions ( half duplex working mode). MODBUS protocol only allows communication between master computer (PC, PLC) and terminal equipment, but don’t allow data exchange between independent terminal equipments, so that each terminal equipment will not occupy communication line during their initialization, and will only occupy the communication line when responsing to query signal sent to it.

 

Master computer query: query information frame includes equipment address code, function code, data information code, check code. The address code shows the selected slave equipment. The function code shows the function the selected slave equipment will execute. For example, function code 03 or 04 requires to read register from equipment and return their content. The data information code includes other additional information about the function the selected slave equipment will execute. For example, in the read command, the additional information includes which register it will firstly read from and the quantity of the registers to be read. The check code are used for checking the correctness of one frame information, providing slave equipments a method of checking if the information content is correct. It uses CRC16 calibration rule.

 

Slave equipment response: if slave equipments generate one normal response, the response information will include slave equipment address code, function code, data information code and CRC16 check code. The data information code includes data collected by the slave equipment, such as register value or status. If error occurs, the slave equipment will not response or return two FF.

 

Transmission mode refers to a series of independent data structure in one data frame and rules for data transmission.
