5 FUNCTIONS USED WITH SSCNET COMMUNICATION
5.8 Compatible Devices with SSCNETIII(/H)
Optical hub unit
The SSCNET/H Compatible Optical Hub Unit (MR-MV200) is a unit that enables the branching of SSCNET/H
communication on 1 line (3 branches for 1 input). SSCNET/H communication can be branched by installing an optical hub
unit in a SSCNET/H system. The optical hub unit is compatible with all slave equipment (servo amplifiers etc.) that supports
SSCNET/H communication. Setting the optical hub unit station settings on Motion CPUs and MT Developer2 is not
required. The power supply of equipment connected to the optical hub unit can be turned OFF/ON (Disconnect/Reconnect)
during operation.
System configuration
The transmission route that passes through the optical hub unit IN connector (CN1A connector for servo amplifier) and OUT1
connector (CN1B connector for servo amplifier) is called the "Main route", and the transmission routes that pass through
OUT2 connector and OUT3 connectors are called the "Sub route". The optical hub unit can only be connected on the main
route. A maximum of 16 optical hub units can be connected on one line, and optical hub units are not included in the number
of connected modules on a line. A connection example using optical hub units is shown below.
