In this program, the digital output values that have been A/D converted using
CH1 and CH2 of the Q62AD-DGH are read by the CPU of the remote master
station.
CH1 performs sampling processing, and CH2 performs averaging processing
every 50 times. An error code appears in BCD if a write error occurs.
(a) Initial settings
• A/D conversion enable channel.............CH1, CH2
