Installing the System Program

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

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).

Usable Support Tools

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-

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).

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

Allocation Areas

Bit notification

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

Bit and Word Allocations to Bit Devices (M, S, X, Y)

The allocation of bits and words to bit devices (M, S, X, Y) is described here. For details on the ranges of the areas within which specification is possible, refer t o “Mitsubishi FX Series PC Allocation Areas” (page 3-11).

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).

Chapter 3-4

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).

3-9

Allocation Areas

Chapter 3-4

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.

Number o f allocated words

1 word

First word

First + 1 word

First + 14 bits

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).
