Precautions for Programming
This section describes the precautions when creating programs for setting the CC-Link IE TSN communication mode.
Program for cyclic transmission
For a program for cyclic transmission, provide interlock between the following link special relay (SB) and the link special
register (SW).
• Own station data link error status (master station) (SB0049)
• Data link status (each station) (SW00B0 to SW00B7)
For details, refer to the following.
User's manual for the master station used

(1) Program for communications with station number 1
(2) Program for communications with station number 2
CC-Link IE TSN Network synchronous communication program
To check the operating status of the FPGA module (synchronous or asynchronous), use the following link special register
(SW) on the master station.
• Synchronous/asynchronous operation status information (each station) (SW01C8 to SW01CF) of the master station
For details, refer to the following.
User's manual for the master station used
An example of a program that turns on and off External output signal Y0 (B0) and External output signal Y1 (B0) of the FPGA
module with station number 1 is shown below.
• X20: Output command
• X100B: Remote READY
• X1000: FPGA controlling flag
• SW1C8.0: Synchronous/asynchronous operation status information (each station) of the station No.1
• Y1010: External output signal Y0 (B0)
• Y1011: External output signal Y1 (B0)
