The NT21, NT31, NT31C, NT631, and NT631C are sophisticated operator inter-
faces (Programmable Terminals) that automatically display information and can
also be used for operations when necessary. The following gives a general de-
scription of the role and operation of the PT for those using a Programmable Ter-
minal (PT) for the first time.
The PT displays real-time information about the system and equipment operat-
ing status, etc. Its power of expression is enhanced by graphs and other visuals,
making the displays easy to understand.

The PT warns of system or equipment failures and prompts the appropriate re-
medial action.
Setting touch switches on the PT allows workers to use the PT as an operating
panel; the results of the operations are transmitted to the host.
