MELSECNET/H network systems support controller-to-controller, controller-to-personal computer, and controller-to-remote I/O station communications. Multiple wiring types are available and many functions designed to increase reliability are included, such as support for redundant systems.
Optical loop type: Communication speeds up to 25 Mbps. Fiber optic cable is immune to EMI/RFI noise. Up to 2 km between stations using GI type cable.
Coaxial bus type: Using low cost coaxial cable allows networks to be constructed at less cost than optical loop networks.
Twisted bus type: The combination of an affordable network module and twisted-pair cables allows a network system to be built at very low cost.
