About this Manual:
This manual describes connecting the NT-series NT31 and NT31C Programmable Terminals to a PLC
(Programmable Controller) or other host and peripheral devices and the settings required for communica-
tions and applications. It includes the sections described below.
Please read this manual carefully and be sure you understand the information provided before attempting
to install and operate the Programmable Terminal.
Section 1 provides fundamental information about the functions and features of the PTs, types of connec-
tion, communication methods, etc. This information will enable you to understand the applications of the
PTs.
Section 2 describes the connection methods that are possible with the PTs, and the functions of the parts
of PTs, as the required knowledge before connecting to the host and to the peripheral devices.
Section 3 describes the settings of the PTs and methods for connection to peripheral devices.
Section 4 describes the method for connecting to the host using the RS-232C port of the PT.
Section 5 describes the method for connecting to the host using the RS-422A/485 port of the PT.
Section 6 describes the operation of the System Menu, focusing on the procedure to start the PT. Func-
tions that are convenient when using the PT and those that are useful for system maintenance are also
explained here.
Section 7 describes the action to take when errors occur in the PT, and how to carry out maintenance and
inspection to prevent the occurrence of errors.
The Appendices provide specifications, dimensions, procedures for using an RS-232C/RS-422A Con-
vertor Unit, procedures for transporting and storing the PT, information on cable preparation, information
on the relationship between the system program and hardware, and product lists.
WARNING Failure to read and understand the information provided in this manual may result in
personal injury or death, damage to the product, or product failure. Please read each
section in its entirety and be sure you understand the information provided in the section
and related sections before attempting any of the procedures or operations given.
