This function skips the conversion processing and error detection processing for unused inputs, and
shortens the conversion time.
Normally in this Unit, the input signals for the number of input points are converted in sequence. The
setting can be changed, so that unused inputs are not converted.
By reducing the number of conversion points, the conversion time is shortened.
Whether the channel is enabled or disabled is settable for each input.
However, set the Ch
Enable/Disable parameter to
Enable
for at least one channel for a Unit.
If you disabled all channels for a Unit, an NX Unit Initialization Error event (event code: 84C10000 hex)
occurs.
Refer to the user's manual for the Communications Coupler Unit for details on events.
