Enhanced PLC-5 controllers
Every PLC-5 controller offers built-in, configurable ports for Data
Highway Plus (DH+) or Universal Remote I/O. A DH+ connection
supports remote programming and information access, in addition to
peer-to-peer communication between the PLC-5, other controllers
and devices. A Universal Remote I/O connection supports real-time
data exchange for I/O, operator interface, and other
third-party devices.
Enhanced PLC-5 controllers
You can add the 1785-ENET sidecar module to any enhanced PLC-5
controller to provide TCP/IP Ethernet connectivity. For more
information, see page 15.
