Overview Section 1-1
Message Service
The message service can send and receive up to 2,012 bytes of data (includ-
ing the FINS header), allowing high volumes of data to be sent and received
without having to split it up.
Twisted-pair Cable or Optical Fiber Cable Connection
The Controller Link Units can be connected to the network using either
shielded twisted-pair cable, H-PCF fiber-optic cable, or GI fiber-optic cable.
Select the system that suits your application.
Features of Optical Fiber Cable
Optical Fiber Cable has superior noise resistance, so this system can provide
highly reliable communications even in very noisy conditions. The fiber-optic
cable allows long-distance and large-scale networks.
With H-PCF fiber-optic cable, the communications distance can be up to 20
km in total (1 km max. between nodes). With GI fiber-optic cable, the commu-
nications distance can be up to 30 km in total (2 km max. between nodes).
Once the Optical Fiber Cable has been fitted with special connectors, the
cables can be easily connected or disconnected.
Features of Twisted-pair Cable
Twisted-pair cable is easy to connect and maintain. The cable can be pro-
cessed much more easily than coaxial or fiber-optic cable, thereby reducing
the cost of tools and assembly time.
Connections are made to a terminal block on the Controller Link Unit and to a
special connector on the Controller Link Support Board for easy system
assembly and modification.
The network is equipped with the required terminating resistance built into the
Units allowing the terminating resistance to be easily set at both ends of the
network using a simple switch.
