When disconnection is detected in a channel for which the "D/A conversion enable/disable setting" is set to "D/A conversion
enable" and the "disconnection detection enable/disable setting" is set to "enable", it is regarded as a disconnection detection
error, and the "disconnection detection flag" turns ON (Error code: 1BB).
At this time, the digital value, digital operation value and analog output value monitor are cleared.
When the "disconnection recovery detection enable/disable setting" is set to "enable", the "disconnection detection flag" turns
OFF when the channel is recovered from disconnection.
