9DEDICATED INSTRUCTIONS
Program example
The following example shows a program that sends any data stored in D11 to D15 using the bidirectional protocol.
When the input/output signals of the Q series C24 are from X/Y00 to X/Y1F:
Transmission command is converted to pulse.
Transmission data is stored.
Designate the number of the interface (CH
) that will send the data.
Clear the transmission result storage device to 0.
Designate the transmission data count in word units. (Designate K10 when the unit is bytes.)
The transmission data stored in the designated device is sent.
After the BIDOUT instruction is executed, the user designated transmission complete signal (M1) turns ON for one scan.
Storing the transmission data and writing the transmission data count in the buffer memory, and issuing a transmission request to Q series C24 are all executed by the PLC CPU.
The completion flag is reset by the external command.
