I/O network Topology
ControlEdge PLC can be configured as a redundant controller system
or non-redundant controller system. It includes provisions for
communication via Ethernet with host systems and the Ethernet ports
provide a layer of protection against cyberattacks. Honeywell
recommends use of Solarwinds and/or Honeywell Risk Manager to
detect unintended and excess network traffic.
ControlEdge PLC supports star and ring I/O topologies for I/O
communication.
Star Topology
The following diagram shows an example of the star topology. A
switch is required for this topology.
