Function
S1·
X0
COLR
K1
Read the coil, Modbus function code 01H.
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).
Operands S3: K1~K2000, the max coil quantity is 2000.
When X0 is ON, COLR instruction is executed. When the instruction starts to execute,
the Modbus read and write flag SM160 (serial port 2) is set on; when the execution is
completed, SM160 (serial port 2) is set OFF. 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.
