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 refer­ring 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 deter­mined by the “Direct Macn Type” data set in the screen data memory board. Ac­cordingly, screen data complying with the programmable controller to be con­nected must be transferred to the PT in advance.
The “Direct Macn T ype” 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

switches. When using NT30/NT30C or NT620S/NT620C, install the system pro­gram for Mitsubishi A computer links in advance using the “NT series system in­staller”.

Reference: Set the other memory switches in accordance with the conditions of use.

The restrictions and cautions that apply specifically when using a PT with a com­puter link system that uses Mitsubishi A series PCs are presented here. For de­tails on other, general restrictions, refer to the Operation manual for the PT.

Screen switching

To switch screens by specifying a screen number in the “screen switch setting” of
the PT status control area, specify the screen number in BCD (binary coded deci­mal).

Specifying memory table numbers

When specifying memory table numbers in the PT status control area, and when
specifying memory table numbers by indirect specification, use BCD (binary
coded decimal).

Allocation Areas

Chapter 2-4

Setting the PT Clock function

When setting the time with the PT’s internal clock function, specify the value in
BCD (binary coded decimal).

Bit notification

When elements for which statuses are notified by bits - such as touch switches,
extended I/O inputs, bit memory tables, etc. - are allocated to word devices (D, W ,
R), since the notification is in word units, all bits other than those used for the notifi­cation will be set to “0” (OFF).

F Bit Allocations

When allocating bits to bit devices, any number not outside the range for the area
can be specified. However, since host link access is in word (16 bit) units, the fol­lowing points must be observed when allocating bits.

S Points to note when allocating to M (special relays) and S (state relays)

M and S devices are bit devices expressed in decimal in the case of Mitsubishi
FX series PCs. However, in the host link, data is written in word (16-bit) units.
Therefore, when data is written, all other bits in the same word are cleared to “0”
(“other bits in the same word” here means bits which have the same quotient
when divided by 16).

S Points to note when allocating to X (input relays) and Y (output relays)

X and Y devices are bit devices expressed in octal in the case of Mitsubishi FX
series PCs. However, host link writing is in word (16-bit) units. Therefore, when
data is written, all other bits in the same word are cleared to “0” (since one word i s
16 bits, each of the following sequences of bits (least significant two digits) is
contained within one word: 00 to 17, 20 to 37, 40 to 57, and 60 to 77).

F Word Allocations

When allocating bits to bit devices, the following points relating to the method of
specification must be observed.

S Points to note when allocating to M (special relays) and S (state relays)

M and S devices are bit devices expressed in decimal in the case of Mitsubishi
FX series PCs. However, inside the PC, the bits are actually managed in units of

16. Therefore, when accessing words using word allocation, make the specifi­cation so that the first bit number is a multiple of 16.

S Points to note when allocating to X (input relays) and Y (output relays)

X and Y devices are bit devices expressed in octal in the case of Mitsubishi FX
series PCs. Therefore, when accessing words using word allocation, ensure
that the least significant two digits of the first bit number are “00”, “20”, “40”, or
“60”.

The area used for word allocation is as follows.

Word Allocations to Word Devices (D, T, C)

Word allocations to word devices (D, T, C) are described here.
It is impossible to make bit allocations to word devices.
Normally one word device occupies one word (16 bits). Therefore, when allocat­ing a word to a word device, any number not outside the range for the area can be
specified. However, in the case of counters C200 and higher, one word device is
32 bits, i.e., it occupies 2 words. For details on the ranges of the areas within which
specification is possible, refer to “Mitsubishi FX Series PC Allocation Areas” (page
3-11).

The area used for word specification is as follows.
