1. OVERVIEW

1. OVERVIEW
1.1 Overview
This user's manual describes the functions, specification, and handling of the
A1SJHCPU general purpose PLC (abbreviated as A1SJHCPU from here on),
A1SJHCPU-S8 general purpose PLC (abbreviated as A1SJHCPU-S8), A1SHCPU
general purpose PLC (abbreviated as A1SHCPU), A2SHCPU general purpose PLC
(abbreviated as A2SHCPU), and A2SHCPU-S1 general purpose PLC (abbreviated
as A2SHCPU-S1).
A1SHCPU, A1SJHCPU and A1SJHCPU-S8 are grouped as A1SHCPU, unless
there is necessity to identify each model.
Also, A1SHCPU, A2SHCPU and A2SHCPU-S1 are grouped as AnSHCPU, unless
there is necessity to identify each model.
The AnSHCPU is a compact-type building block PLC. The model is one third the
size of the conventional building block type PLC, and allows easy operation in spite
of its small size.
AnSHCPUs are miniature building block programmable controllers, which have
been downsized to occupy one third of the volume of conventional building block
type programmable controllers, and are designed to be easy to use in spite of their
small size.
Sequence programs that have been created for the existing A0J2CPU, A0J2HCPU
and A[ ]NCPU models can be used by changing the CPU module type specification
for the program. Moreover, since modules for use with A[ ]NCPU can be used by
installing them on an extension base unit for A[ ]NCPU use, it is possible to extend
the functions of an AnSCPU.
The AnSCPU has functions equivalent to those of the A2NCPU and we urge you to
make the best use of these functions in order to use the equipment efficiently.
This user's manual refers to peripheral devices by using the following abbreviations.
A7PHP, A7HGP, A6GPP, A6PHP, and IBM PC/AT
(started up with SW3IVD-GPPA, MELSEC MEDOC, MELSEC MEDOC plus)
A7PUS, A8PUE
...................................Abbreviated as "GPP function".
