IP67 Digital I/O Modules for EtherNet/IP
3. System Description
Overview
HarshIO eIP modules can be used with a protocol compliant scanner as part of control system
architecture. The modules’ built-in unmanaged 2-port Ethernet switch allows you to use the network topology
that meets your application needs. These topologies include the following:
star
daisy-chain
combination of star and daisy-chain
Star topology
Star topology allows you to connect mixed I/O modules or additional equipments. Performing
maintenance on one module – for example, by removing the network cable, or by cycling power to the
module – does not affect other modules.
