/MELSEC-A

This manual gives the system, specifications and handling of the
A2CCPU General-purpose Programmable Controller (referred to

as

A2C

in

this manual).

The

A2C is a baseless building block type CPU which does not use

a

base

unit

for system construction which includes remote

110

and

terminal modules

(*1).

The

A2C uses the MELSECNET/MINI-S3 data link system

(*2)

(referred to as MINLS3

in

this manual)

in

place

of

a

base unit for

data communication with the remote

VO

module

and

the remote
terminal module through 5core flat cables or twisted pair cables.
Using Score flat cables, the system modules can be arranged
close to each other just as the building block type CPU is used.

Using twisted pair cables, the system modules can be separated

up to

100

meters (328.1

ft)

away from each other

(*3).

This feature

makes

it

possible to install the remote I/O module and the remote

terminal module to suit with

controlled.

ON/OFF data communication

is

performed using inputs

(X)

and

outputs

(1)

Inputloutput number assignment

of

the remote

in the order of the station number

(1

to

module.

Data communication with

a

remote

I/O

module

is

performed

using inputs

(X)

and outputs

(Y)

assigned for each module.

See Section

4.7

for the relationship between station numbers

and

I/O

numbers.

(2)

ON/OFF data communication with the remote

is

performed in the refresh mode.

Power supply for the

A2CVO

module and the

A2C

special
function modules
The

A2CVO

modules and the

A2C

special function modules

require

24

VDC

power supply. Use the

A66PC

power supply

module or

a

general-purpose

24 VDC

power supply.

(5)

Both remote

I/O

modules and remote terminal modules, when

used with the

A2C,

need station number setting.

If

two

or more different modules are

set

for one same station

number, incorrect input and output will occur. Make sure that

there are no modules which are

set

for one same station

number before the power

is

turned

ON.

See Section

4.7

for details of station setting.

(6)

To

eliminate incorrect input

at

the remote

I/O

modules, design

the

A2C

system considering the following.

a)

Measures on turning

ON

and

OFF

the power

1)

When turning

ON

the power, turn

ON

the remote

I/O

modules first, and then, turn

ON

the

A2C.

Or, turn

ON

the

A2C

and the remote

I/O

modules together

at

the

same time.

2)

When turning

OFF

the power, turn

OFF

the

A2C

first, and

then, turn

OFF

the remote

I/O

modules.

Or,

turn them

OFF

together

at

the same time.

Power supply for the remote

110

modules indicates the following.

1)

UO

module power supply: Power supplied to the

WO

moudle power supply is

converted to

5

VM:

inside the system and used in the internal circuit of the

I/O

module.

2)

Cause for incorrect input due to momentary power
failure

The

inside the module.

If momentary power failure occurs in the
