1. INTRODUCTION

This manual gives the system, specifications and handling of the A2CCPU,

A2CCPUP21 and A2CCPUR21 General-purpose Programmable Controller

(referred to as A2C in this manual).

The A2C is a building block type CPU module which can construct asystem

including remote I/O modules (I/O modules) and remote terminal modules

(special-function modules)

(*')

without using abase unit.

The A2C uses the MELSECNET/MINI-S3 data link system (*2) (referred to as

MINI-53 in this manual) in place of a base unit for data communication with

the

remote I/O module and the remote terminal module

through

s-core flat

cables or twtsted-pair cables.

Using s-core 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

It)

away from each other

(*1.

This feature makes it possible

to install

the

remote I/O module and the remote terminal module to conform

with the arrangement of equipment to be controlled.

for names and types of the remote I/O modules and the remote

(2)

.,.

The MELSECNET/MINI-S3 data link system has been designed to reduce the amount

of wiring between the PC and equipment to be controlled. Since the PC, the remote

I/O module and the remote terminal module are connected with twisted-pair cables

or optical fiber cables, it is possible to install the remote I/O module and the remote

terminal module to suit with the arrangement of equipment to be controlled.

The maximum allowable distance is 50 meters (164.1

Description

Operation

Thissection describesthe datacommunication between

the

A2C,

the

remote

I/O module and

the

remote terminal module.

See Section 4.2

for

the A2C functions.

1.1.1 ON/OFFdata communication between the A2C and the remote I/O module

ON/OFF data communication is performed using inputs (X) and outputs

(Y).

(1) Input/output number assignment of

the

remote I/O module

The

input/output

numbers of the A2C system are assigned from x/yOOO

to X/y1FFin

the

order ofthe station number

to 64) set

for

each remote

I/O module.

Data communication with a remote I/O module is performed using ..

inputs (X) and outputs

(Y)

assigned

for

each module.

'Ill

See Section 4.7 for

the

relationship between station numbers and i/O

numbers.

(2) ON/OFF data communication with

the

remote I/O module

The ON/OFF data communication with the remote I/O module is per-

formed in the refresh mode.

remote I/O modules. ,
