SMC02 Stepper motor controller communication protocol
V1.0

Protocol Introduction
Using TTL serial transmission interface and MODBUS-RTU communication protocol, this product only supports function codes 0x03, 0x06, and 0x10.

Introduction to Communication Protocol

Information transmission is asynchronous in Modbus-RTU mode

Starting bit	1 bit
Data bits	8 bit
Parity bit	not have
Stop bit	1 bit

Data frame structure

Data frame interval	Address code	function code	data area	CRC check
3.5 bytes or more	1 byte	1 byte	N byte	2  byte

Before sending data, it is required that the data bus rest time, i.e. no data transmission time, be greater than 3.5 (e.g. 5ms at a baud rate of 9600). Message transmission must start with a pause interval of at least 3.5 bytes, and the entire message frame must be treated as a continuous data transmission stream. If there is a pause time of more than 3.5 bytes before the frame is completed, The receiving device will refresh incomplete messages and assume that the next byte is the address field of a new message. Similarly, if a new message starts with the previous message within less than 3.5 characters, the receiving device will consider it a continuation of the previous message.

Address Code
The address code is the first byte (8 bits) of each communication information frame, ranging from 1 to 255 (initially set to 1,0 and also the broadcast address). This byte indicates that the slave set by the user will receive information sent by the host. Each slave must have a unique address code, and only slaves that match the address code can respond to feedback messages. When the slave sends back information, the returned data starts with their respective address codes. The address code sent by the host indicates the slave address to be sent, while the address code returned by the slave indicates the slave address to be returned. The corresponding address code indicates where the information comes from. 1.2 Function Code
The function code is the second byte transmitted in each communication information frame, and the ModBus communication protocol can define function codes ranging from 1 to 127. Sent as a host request, telling the slave what action to take through a function code. As a response from the slave, the function code returned by the slave is the same as the function code sent from the master, and indicates that the slave has responded to the master and performed relevant operations. This machine only supports function codes 0x03, 0x06, and 0x10.

FAQs

• Q: How do I set the motor to rotate in a specific direction?
  A: Use the forward rotation speed setting for clockwise rotation and the reverse rotation speed setting for counterclockwise rotation.
• Q: What is the purpose of the cycle work times setting?
  A: The cycle work times setting allows you to specify the number of repetitive cycles the motor should perform before stopping.
