9.1 Precautions for Programming
This section describes precautions to create CC-Link IE TSN programs.
Cyclic transmission program
For a cyclic transmission program, interlock with the following link special relay (SB) and link special register (SW).
• Own station data link status (master station) (SB0049)
• Data link status (each station) (SW00B0 to SW00B7)
User's manual for the master station used
Interlock example
CC-Link IE TSN Network synchronous communication program
For a CC-Link IE TSN Network synchronous communication program, interlock with the following link special register (SW).
The program is to check that I/O module operation is synchronized properly.
If the module operation is not synchronized due to a factor such as an error, prevent an unintended operation by stopping I/O
control.
• Synchronous/asynchronous operation status information (each station) (SW01C8 to SW01CF) of the master station
User's manual for the master station used
Example of interlock when X0 and Y10 of the I/O module on the station No.1 are assigned to X1000 and Y1010 of the CPU
module respectively
(1) Program of communication with a station with station number 1
(2) Program of communication with a station with station number 2
(1) Synchronous/asynchronous operation status information (each station) of the station No.1
(2) X0 of the station No.1
(3) When X0 of the I/O module turns on, Y10 turns on.
