NX-series Data Reference Manual (W525)
The number of output points provided by the Unit.
This is the polarity that the Unit uses to connect to output devices.
There are models with NPN and PNP connections.
The maximum output load current of the Unit. Specifications for each output point and for the Unit
are described.
The rated output voltage of the Unit.
The I/O refreshing methods that are used by the Unit.
Free-Run refreshing, synchronous I/O refreshing and output refreshing with specified time stamp
are available.
In the following table, the following abbreviations are used.
Free: Free-Run refreshing
Sync: Switching synchronous I/O refreshing and Free-Run refreshing
Specified time: Output refreshing with specified time stamp
The delay time for which data in the internal circuit is reflected in the state of output elements of the
Unit.
It is described according to the ON/OFF sequence.
