1.2 Outline
1. EH-ETH (This after called this module) can be mounted onto the basic base of EH-150 system and is the
communication module can be connected EH-150 system to Ethernet based on IEEE802.3.
2. This module connected to Ethernet will operate as one of the station of the network system. For this operation this
module can exchange the data with personal computer or engineering workstation connected with network.
1.3 Feature
1. The data sending or receiving connection can be used 10 at once.
- 6 connections for automatic send/receive and 4 connections for H-series protocol (Taskcode communication) can
be used.
- Sending data and receiving data can be done with one connection.
- It is selectable TCP/IP or UDP/IP as the communication protocol for each connection.
- The maximum sending or receiving data size between PLC and PLC or PLC and host computer is 1,454 bytes.
2. Saving the developing power with using Web server function and Automatic sending/receiving function.
- The all configuration for communication can be done with using Web browser before to start communication.
The configured data for communication can be saved with text format file.
- It is possible to save the development power for communication program using Ladder diagram can be saved with
using the automatic sending /receiving function.
3. Using programming software called LADDER EDITOR for Windows® via Ethernet communication line.
- It is possible to monitor the I/O data or to handle the program of PLC with LADDER EDITOR for Windows®
via Ethernet communication line. You can save the time and cost for maintenance of user program or total
system.
