MELSECNET/MINI-S3

A High Speed Remote I/O Networking System

■ Up to 512 remote I/O points

The MELSECNET/MINI-S3 remote I/O networking system

allows a wide variety of remote I/O modules to be con-

trolled by a central station. A maximum of 64 remote

stations can be connected to one network loop, either using

fiber optic and/or twisted pair cables. Up to 512 points of

data can be refreshed between the master and remote

stations in less than 3.2ms.

■ RS232C interface unit

Communications with devices such as bar code readers and

ID controllers is possible when connecting this unit to

MELSECNET/MINI. Other general purpose devices can also

communicate with this unit using a no protocol format.

AJ71PT32-S3/AJ71T32-S3

MELSECNET/MINI-S3 master module

The AJ71PT32-S3/AJ71T32-S3 MELSECNET/MINI-S3 master

module allows the host QnA/A Series PLC to control up

to 64 remote I/O stations connected on the MELSECNET/

MINI-S3 networking system. The master module carries out

high speed communication processing with the remote

units connected to the network it controls. More than one

master module can be used per PLC CPU, up to the

maximum I/O points of the host CPU.

AJ71PT32-S3 is compatible with both fiber optic and

twisted pair cable networks.

AJ71T32-S3 is compatible with twisted pair cable networks.
