Communication agreement
The physical layer
communication interface, the asynchronous half-duplex mode Communications speed can be set to 1200-9600 BPS, the factory default 2400 BPS Byte transfer formats: one start bit, 8 data bits, parity (N81, E81, 081) optional, factory default E81
Digital communication protocol:
The controller provides asynchronous duplex RS485 serial communication interface and adopts the MODBUS-RTU protocol, all kinds of data information can be transmitted on the communications lines. One route can connect to 32 network controller at the same time, each controller can be set different mailing Address (the Address No.), different series controller communication terminal number is different, the communication connection is shielded twisted-pair cable should be used with copper net, wire diameter is not less than
0.55 mm. Wiring should keep communication lines from high voltage cable, or other strong electric field environment, T type is recommended for the network connection (see figure 1), but does not recommend a star or other contact way

supply
The MODBUS-RTU communication protocol uses the master-slave communication response mode connections on a communication line. First of all, the main computer of the signal only address addressing to a terminal equipment (machine), and then, the response signal from the terminal to transmit to host in the opposite direction, i.e., in a single communication line signal transmission instead of two direction all communication data flow (half duplex working mode). MODBUS protocol is only allowed on the host (PC, PLC, etc.) and the communication between the terminal equipment (see chart 2), and does not allow independent data exchange between terminal equipment, so that each terminal equipment not occupy the communication line when they are initialized again, but only in response to the native query signal

The host query:
Query message frames includes device address, function code, data, information, check code. Address code informs the machine that is selected to perform the destined function equipment, such as functional code 3 or 4 is for registering the data which is read from the device and return their content; Contains data from the device to perform functions other additional information, such as reading command, data segment additional information start from how to register and number of registers to read; Check code is used to test the correctness of the a frame information, provides from the device with a validation message content is the right approach, it adopts CRC16 calibration rule
If from the device to produce a normal response, in response to the message from the machine address code, function code, code and data information CRC16 check code. Data information code, including the data collected from the device, such as register values or state. If there are errors, we agreed from the machine does not respond. Transport refers to a data frame in a series of separate data structure and used for the transmission of data limited rules, defines the RTU mode compatible with MODBUS agreement under the mode of transmission. Each byte: a start bit, 8 data bits, parity bit (,), 1 stop bit (a parity bit) or 1 stop bit (and white parity bits).
The structure of the data frame:(Message format) Table 1
Address Code
ONE
Address Code
At the beginning of a frame by a byte (eight binary code), the decimal is 0-255, only use the 1-247 in our system, the other address. These bits indicate the address specified by the user terminal equipment, the device will accept data from the connected to the host. Each terminal equipment address must be unique, only by addressing to the terminal response contains the address of the query. When the terminal sends back a response, in the response from the machine address data and tell the host which terminal is to communicate with them.
Function Code: (Table 2)
Tell what is addressing to the terminal to perform the function. Listed in the following table shows the supported code function, and their meaning and function

Check code:
Error check (CRC) domain are two bytes, containing a 16-bit binary values. CRC value is calculated by the transport equipment, and then attached to a data frame, the receiving device to recalculate the CRC value when receiving data, and then compared with acceptance to the CRC in the domain of value, if the two values are not equal, an error has occurred. As shown in figure 3
