Program example
1) Create the following program in the project for the master station using GX
Works2.
POINT
• If a response is not received for several link scans, the station is determined as a
cyclic transmission faulty station, and the status is stored in Data link status (each
station) (SW00B0 to SW00B7).
2) Write the program to the CPU module on the master station. Then reset the
CPU module or turn off and on the power.
