NX range offers exceptional value for money. Available in two screen sizes (128x64 and 240x128) with an optional touch screen it has full monochrome graphics capabilities and supports all of our I/O systems (SmartStack, SmartStix, SmartMod) at the same time. This I/O capability coupled with the dual protocol capabilities, Ethernet and Fieldbus support, makes the NX a fantastic systems gateway.
Depending on your application needs the NX offers incredible power for a good price. The OCS with its full IEC61131-3 integrated development environment for logic, HMI design, networking and I/O configuration is a very capable PLC with full graphics capability.
The operator interface used in the NX series is a high visibility graphics monchrome LC-Display with green adjustable backlight offering excellent readability to the user in the most difficult conditions.

I/O, Communications options for any application
Choose any module from our extensive SmartStack, SmartStix and/or SmartMod I/O. Two serial ports support many protocols giving the abillity to connect to virtually any serial device. Add a Fieldbus option such as CAN (CsCAN or CANopen), DeviceNet or Profibus DP among others and the NX becomes a truely remarquable gateway between your process, the user and the supervision over Ethernet.
Note: Future firmware will enable programming the NX through the USB slave port. Currently this port is not functional.
