Program conditions
The digital values of CH1 and CH2 of the Q62DA-FG are written and their output
monitor values are read to the programmable controller CPU of the remote
master station.
If a digital value write error occurs, the corresponding error code is displayed in
BCD.
(a)
Initial settings
• Analog output enabled channel .................... CH1, CH2
• Rate control enabled channel ....................... CH1 (increase digital limit
• Disconnection detection enabled channel ... CH1
• Warning output enabled channel .................. CH2 (warning output upper
