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

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).

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
Communication message example

Response data (from the machine frame), indicating that the data has been written. (table 6)
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.
