NT21-ST121-E - Programmable Terminal - OMRON

Versatile I/O and high-capacity screen memory in a space-saving format

Small size, big screen

The LCD screen is larger than that of the OMRON NT20S (increased from 256 x 128 dots to 260 x 140 dots), but the panel dimensions and cutout size are the same.

Plenty of capacity to record graphic screens

With 512KB of memory capacity, there is more than enough space to store screen data.

Two RS-232C ports

Two RS-232C ports in the NT21 (compared to one in the NT20S) allow simultaneous connection of a PLC, Barcode Reader and NT Support Tool (connectable to serial port A only).

Versatile communications

In addition to Host Link and 1:1 NT Link communications, the NT21 supports high-speed 1:N NT Link and Memory Link communications.

Function support equivalent to that of a mid-sized operator interface

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 a simple touch screen PT operation. For example, tuning parameters for separate models can be changed on the PT and then written or read from the PLC.

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.

The NT21 is equipped with many of the same functions 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 makes it possible to perform scaling and other mathematical operations automatically in the PT
