Description
UTNH23A optical shared hub unit UTNH series
The optical shared hub unit UTNH series (called the optical shared hub unit in this
manual) for the information and control network TC-net 100 constitutes TC-net 100
optical transmission lines. It employs an MT-RJ optical connector with 8 ports.
The hub unit also has one port for the RJ-45 modular connector, which may be
connected to a TC-net 100 (twisted pair) device. In using a single unit, use the optical
shared hub unit for line A transmission line UTNH23A (SNMP installed for TC-net 100) or
optical shared hub unit for line B transmission line UTNH23B.

TC-net 100 is a monitor and control LAN for the Integrated Controllers, which can be
configured using optical fiber transmission lines and twisted-pair cable transmission
lines. The optical shared hub unit is necessary for configuring optical fiber transmission
lines, and connects TC-net 100 stations to the network.
The UTNH23A, which has SNMP for TC-net 100 mounted in it, permits diagnosis of the
ports connected to the optical shared hub unit.
The standard TC-net 100 has dual transmission lines, of which line A is for connecting
UTNH23A and line B for connecting UTNH23B.
The information and control network TC-net 100 has the following features.
• Open
The TC-net 100 is a monitor and control network featuring the open characteristic of
the 100-Mbps Ethernet, collision averting function, and definitive time response.
• Communication service
Communication service covers scan transmission (cyclic broadcast transmission and
reception) for periodic control data transmission and ordinary message transmission.
• Scan transmission has three modes: High-speed mode, medium-speed mode,
and low-speed mode. These modes can be assigned according to the data
refreshing cycle to assure definitive real-time response.
• Message transmission is supported by not only TCP, UDP, and IP but also the
Toshiba standard protocol PCMP.
• High reliability
High-reliability systems can be built by dual transmission line configuration. Electric
or optical transmission lines can be selected.
