Using the ELC-PV Controller and the ELC-COENETM Ethernet Module to
Control and Monitor I/O Data from Distributed I/O Adapter ELC-CAENET
via Modbus TCP Ethernet
This application example will demonstrate how to set up an ELC-COENETM Ethernet module
to read and write I/O data from an ELC-CAENET Ethernet distributed I/O adapter. The software
used to configure the adapter and the COENETM module is called ECISoft and is included in
ELCSoft.
The system used for this application example consists of the following:
(1) ELC-PV28 controller
(1) ELC-COENETM Ethernet module (Modbus TCP protocol)
(1) ELC-CAENET Ethernet distributed I/O adapter
(1) ELC-PS02 24vdc power supply
(1) Ethernet switch 10/100mbps
(3) Ethernet patch cables
Both Ethernet modules are connected to the switch along with the computer running ECISoft.
The Subnet mask used for all devices is: 255.255.255.0. The IP addresses used for each
device are:
1.
ELC-COENETM
120.151.1.2
2.
ELC-CAENET
120.151.1.3
3. Computer running ELCSoft/ECISoft 120.151.1.1
Configuring the ELC-CAENET Distributed I/O Adapter
ECISoft is used to configure the ELC-CAENET adapter. Start ELCSoft 2.0 or later, and then
click the ECISoft button shown below. Note that when the curser is over the ECISoft button, it
displays ECISoft. Use this to verify that you’re clicking the correct button.
