AJ71E71-S3

Ethernet module

The AJ71E71-S3 is an ethernet network interface module which

allows the host PLC CPU to be directly connected to an

ethernet network system. It supports TCP/IP and UDP/IP

protocols with the possibility of using either ethernet 10 BASE5

or 10 BASE2 simply by switch selection. The interface

conforms with IEEE standard 802.3 (CSMA/CD) and features

transmission speeds of up to 10M bps.

Device reading/writing, program uploading/downloading and

remote run/stop controlling are all possible using dedicated

instructions from any node on the ethernet system.

Communications with other PLCs connected onto MELSECNET

II and MELSECNET/10 is also possible.
