(*1) In order to use NT30/NT30C, NT620S/NT620C in multi-vendor systems, a
dedicated system program must be installed in the PT using the “NT series
system installer”.
The relationship between the PCs that can be connected and the direct connection

Installing the System Program Chapter 1-2
1-2 Installing the System Program
In order to use an NT30/NT30C or NT620S/NT620C in a multi-vendor system, a
dedicated system program must be installed in the PT using the “NT series system
installer” shown in the table below.
Model Applicable PC
NT30-ZS3AT-EMV1 Mitsubishi A series
Mitsubishi FX series
NT620-ZS3AT-EMV1 Mitsubishi A series
For details on how to operate the system installer, refer to its instruction manual, or
the PT Operation manual.
Reference: Since NT20S and NT600S already have a dedicated system program written into
them, this installation is not required for them. However, some PT models cannot
be used in multi-vendor systems: check the situation for the model used by refer-
ring to “1-1 Possible Combinations”(page 1-2).

1-4
Usable Support Tools Chapter 1-3
1-3 Usable Support Tools
When using the PT in a multi-vendor system, one of the following support tools
must be used.
NT-ZA3AT-EV2 (Ver.2.3j)
The programmable controllers (PC) that can be connected to the PT are deter-
mined by the “Direct Macn Type”data set in the screen data memory board. Ac-
cordingly, screen data complying with the programmable controller to be con-
nected must be transferred to the PT in advance.
The “Direct Macn Type”is set with the support tool. The applicable programmable
controllers (PCs) depending on the “Direct Macn Type”setting are as follows.
Direct Macn Type Applicable Programmable Controller (PLC)
NONE For connections without direct connection (e.g. RS-232C)
OMRON For connection to an OMRON C series or CVM1/CV se-
ries PC, or for a memory link connection.
MEL-A For connection to a Mitsubishi Electric MELSEC A series
PC
MEL-FX For connection to a Mitsubishi Electric FX series PC
