3.2 Transmitting Data to Target Device
Program for data transmission
Program example for data transmission
The following shows the program for data transmission using nonprocedural protocol and its example.
For details on OUTPUT instructions, refer to the dedicated instruction. (Page 520 Dedicated Instructions)
Start the programmable controller on the host station.
The value set with Engineering tool is stored in the C24.
 Input the user data transmission command signal.
 Executes the OUTPUT instruction after storing the send data and the control data for the OUTPUT instruction in the
device.
Data is sent when the OUTPUT instruction is executed.
 C24 transmission processing completes and the OUTPUT instruction completion device turns ON.
When the completion device +1 (abnormal completion signal) turns ON, the error code is stored in the control data completion
status (S1+1).
