
Read register, Modbus function code is 03H.

Serial port: K0~K5. K0: Port0 (RS232), K1: Port1(RS232), K2: Port2(RS485), K3:
Port3(left extension port), K4: Port4(above extension port 1), K5: Port5(above
extension port 2).

Operand S3: max register number is 125.

When X0 is ON, REGR instruction is executed, Modbus read write flag SM160(serial
port2) is set ON, SM160 is set OFF when the execution is completed. If a
communication error occurs and the number of resend is set, it will be automatically
resend. Users can check the relevant registers to determine the cause of the error. The
execution result of Modbus read and write instructions of serial port 2 is in SD160.
