ELC-CAENET
To ensure correct installation and operation of ELC-CAENET, please read this chapter carefully
before using your ELC-CAENET. The ELC-CAENET is an Ethernet remote I/O adapter product
that connects ELC I/O modules to Ethernet networks using either EtherNet/IP or Modbus TCP
protocols. To configure the ELC-CAENET module use EATON's ELCSoft and ECISoft or an
embedded web page on the device.
The ELC-CAENET supports Modbus TCP server protocol and can be used as remote I/O from
a PLC or other Modbus TCP client devices. The ELC-CAENET can also be used as a Modbus
TCP gateway, supporting the conversion from Modbus TCP commands to Modbus ASCII/RTU.
The ELC-ENET also supports EtherNet/IP adapter functionality to provide remote I/O for a PLC
capable of being an EtherNet/IP scanner.
