A Programming Device can be connected to the USB port, serial port A, or
serial port B (Display Section). The functionality of serial ports A and B are the
same as the ports on an NS-V2-series PT. If a Programming Device is not
connected, a barcode reader, temperature controller, or other device can be
connected.
Serial port C (Controller Section, RS-232C) has the same functionality as the
RS-232C port on a CJ1-H CPU Unit with unit version 3.0. It can be used for a
Host Link, NT Link, non-procedural, or serial gateway (CompoWay/F) connec-
tion.
The Controller Section provides DeviceNet master functionality as a standard
feature. I/O can be controlled and message communications performed using
DeviceNet within the limitations of the DeviceNet communications cycle.
Memory Cards are optional for both the Controller Section and Display Sec-
tion.
The user must provide a 24-V DC power supply.
DeviceNet is a multi-vendor network consisting of multi-bit control and infor-
mation systems and conforms to the Open Field DeviceNet specification.
Using the DeviceNet master functionality enables remote I/O communications
between the NSJ Controller and the slaves on the network. Remote I/O com-
munications enable large-capacity I/O and user-set allocations. Analog I/O
Terminals and other devices are used for the slaves. Message communica-
