11.1 Precautions in Programming
This section describes precautions in creating a program.
1. Create a read program from the remote input RX after data link startup. Create a write
program to the remote output RY at the end of the entire program.
2. Create such a program that read of received data and write of transmission data are
executed after the master station becomes the data link status (after the BFM#10 b1 turns
ON).
