Design and Operating Procedure Examples Section 1-6
System Configuration
Layout • Wiring form: Branching from trunk line to branch lines, with no sub-branch
lines
• Wiring distance: 30 m or less, so any cable type or baud rate is accept-
able.
• Communications Power Supply to Slave Units: Supplied to all collectively.
■ Remarks
Wiring Form
• When there is no branching, any combination of cable types and baud
rates are supported.
• When there is a branch, Round Cable I, Round Cable II, Flat Cable I and
Flat Cable II cables cannot be used at a baud rate of 4 Mbps. This means
you cannot use a Bit Slave Unit with a pre-attached cable at 4 Mbps.
When a Round Cable I cable is used at a baud rate of 1.5 Mbps, the trunk
line and the sub-trunk line must be no longer than 30 m.
• When a branch line has a sub-branch line, Round Cable II, Flat Cable I, or
Flat Cable II cables must be used either at a baud rate of 1.5 Mbps or
93.75 kbps.
