Versatile I/O and large capacity - Screen memory in a space-saving size
Small size, big screen
The LCD screen is larger than the OMRON NT20S (up from 256 x 128 dots to 260 x 140 dots), but the exterior dimensions and panel cutout size are the same.
Two RS-232C ports
Two RS-232C ports in the NT21 (compared to one in the NT20S) allow simultaneous connection of a PLC, Bar Code Reader and NT Support Tool (connectable to serial Port A only).
Plenty of capacity to record graphic screens
With 512 KB of memory capacity, there is more than ample space to store data.
Versatile communications
In addition to Host Link and 1:1 NT Link communications, the NT21 supports high-speed 1:N NT Links and Memory Link communications.
Highly reliable hardware
Complies with international standards
The NT21 complies with CE directives, as well as UL, cULus (Class 1 Div2) and C-Tick. The front panel has an ingress protection equivalent to IP65F.
Function support equivalent to that of a mid-size operator interface
Recipe function
Parts tables on the PT screen can be used to set multi-word data into records, which can then be written into the PLC by simple operation of the PT touch screen. For example, setting parameters of separate models can be changed on the PT and then written or read from the PLC.
List/History of alarms
An alarm message can be displayed in response to the state of the PLC bit, and the content and time of the message can be stored as an alarm history.
Programming console function
The NT21 is equipped with many of the same features as the SYSMAC PLC Programming Console.
Math functions
Up to 256 mathematical equations can be stored in the PT processing table to enable automatic PT processing, and the results can be written to the digital memory table or other destinations. This allows scaling and other mathematical operations to be performed automatically in the PT.
Upgraded version of NT Support Tool (-EV4.7)
Enhanced Editing Functions
• I/O comments in CX-Programmer I/O tables can be used directly.
