NX-series Data Reference Manual (W525)
The summary specifications of the Units to configure the CPU Rack or Slave Terminal.
Use this as a guide to select the Unit model when you consider the Unit configuration.
The items in the Summary Specifications depend on the Unit type. The meaning of each item is
explained for each Unit type.
I/O power supply method The method for supplying I/O power supply for the Unit.
The supply method depends on each Unit.
The power is supplied from the NX bus or the external source.
NX bus: Supply from the NX bus
External: Supply from external source
The CPU Unit, Communications Coupler Unit, and the Additional I/O
Power Supply Unit do not have this item.
Yes
Weight The weight of the Unit. Yes
Width The width of the Unit. The unit is "mm". Yes
I/O data size
*3
The I/O data size of default value that the Unit consumes. The unit is
byte.
However, the unit is bit for some Digital I/O Units. In this case, the unit
is given in the table.
It is described according to the input/output sequence.
No
*4
Yes
Number of I/O entry map-
pings
*3
The number of I/O entry mappings of default value that the Unit con-
sumes.
It is described according to the input/output sequence.
No
*5
Yes
Number of cyclic communi-
cations connections
*6
The maximum number of connections that can be set by Class 1 mes-
sages.
No Yes
*1. CPU Units do not have this item. This item is defined as the Unit power consumption from the Unit power sup-
ply.
*2. The Communications Coupler Units do not distinguish between the CPU Units and Coupler Units because they
cannot be mounted to the CPU Unit.
*3. CPU Units do not have this item.
*4. The CPU Unit provides a sufficient margin of capacity for the data size required to allocate NX Unit I/O data.
For this reason, it is not necessary to consider the I/O data size of the connected NX Units.
*5. There is no restriction for CPU Units.
*6. This item is only for EtherNet/IP Coupler Units.
