4-3-3 Remote I/O Area Data Configuration
The Network Configurator can be used to specify the data transferred by the
NE1A-series Controller as Safety Slave or Standard Slave input data. This
section describes the data that can be set, the setting method, and the data
configuration.
Configuration of Data To Be Transferred
The Pre-Ver. 1.0 NE1A-series Controllers can combine status data and I/O
data and transfer them as remote I/O data.
NE1A-series Controllers with unit version 1.0 or later (including Controllers
that support EtherNet/IP) can combine status data, local I/O monitor data, and
I/O data and transfer them as remote I/O data.
The data that is transferred is determined by the configuration. The data is
normally configured of status data, local I/O monitor data, and I/O data, in that
order. The status data can be collected in the PLC to create a monitoring sys-
tem. The data can also be configured of only status data, only local I/O moni-
tor data, or only I/O data.
