The NT31, NT31C, NT631, and NT631C are sophisticated display units (Pro-
grammable Terminals) which automatically display information and can also be
used for operations when necessary. The following gives a general description
of the role and operation of the PT for those using a Programmable Terminal
(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.
