2. Program Instructions

2.1 PLC Serial Port and Free Protocol Configuration

(1) Serial port configuration (default):

Baud rate: 115200
Parity: None
Data bits: 8
Stop bits: 1

(2) Free protocol example:

Receive byte-count register: %MW0/%MB0
Receive data start address: %MW1/%MB2
Max receive length: 256
Send byte-count register: %MW300/%MB600
Send data start address: %MW301/%MB602
Max send length: 256

2.2 Serial Data Write (via Function Block Library)

0 ------- Servo ID
3600 -- Target angle 360.0°
3000 -- Reach target in 3000ms (3s)
100 ---- Acceleration time 100ms
100 ---- Deceleration time 100ms

Use function blocks to convert and pack data into a custom send array, then assign values from SendBuf to the serial send start address in order.

2.3 Serial Data Send

After protocol packet data is written to the serial send registers, set the send byte-count register to the number of bytes to send (non-zero) to transmit successfully. After successful transmission, the register is automatically reset to zero.

3. Importing Library Files

In InoproShop, go to the project tab and import all FB libraries via PLCopenXML.

After importing, drag function blocks from the toolbox and fill in required parameters.

4. Function Block Description

4.1 Angle Control

ID: servo ID
Angle: target servo angle (3600)
Interval: time to reach target angle
AccInterval: acceleration time
DecInterval: deceleration time
Power: output power

Note: when writing SendBuf data to serial send registers, data must be sent sequentially and continuously. The send byte count must also be set to the actual packet length.
