Get the advantages of using Omron’s NT31/NT631 operator interfaces with a PC or single board computer for an economical
control/display package. The Memory Link feature translates PC serial output to operator terminal protocol and communicates display
status back to the PC. A common memory table stores the shared data. This arrangement capitalizes on the strengths of each
component: the PC control platform handles the controls and the operator terminal handles the display tasks. Here is how Memory Link
can keep costs down.

Serial Data Exchange Commands
The NT31/631 writes its memory and memory table information to the internal Memory Link area. Data is then processed
between this area and the host via serial commands. Here are the commands available:
Data Read Commands/Responses
These commands are used for reading the contents of the NT
memory and memory tables. They are issued from the host and
the NT unit responds by returning the requested data from the
specified Memory Link table location.
•
•
•
•
•
•
Notify
These commands are used to notify the host of NT operations.
They are issued from a Memory Link table location of the NT unit
and require no response from the host.
•
•
•
•
•
Re-Send
This command allows the NT unit to re-send the last sent notify
command to the host. It is issued from the host.
•
Display the output from an embedded PC, PC104 or other serial
device without having to install a video board or other converter
hardware
Eliminates the need to write your own or use third-party
graphical user interface software to create graphics for
touch screens
Reduces installed hardware costs by using low-cost processors
Easy to customize the display for short runs of machines

Specifications
• Up to 10,000 words of internal memory allocated for reading and
• Serial communications: RS-232 or RS-422 connection
• Transmission distance between touch screen and PC:
Data Write Commands/Responses
These commands are used for writing data to the NT memory
area. They are issued from the host to update NT memory area
with new data. The NT screen objects and memory tables
reference the memory area and display the new data values. The
NT can be set to respond back to the host indicating whether or
not the data write was completed successfully.

Operation Mode Switch
This command is used to switch operating modes of the NT unit
either “Run” to “Transmit” or from “Transmit” to “Run.” It is
issued from the host
•
Error Response
This command is to notify the host that the command sent
contained an error. It is issued from the NT unit to the host.
