Duplex Connecting Cables

Data is transferred
simultaneously
between the CPU Unit
and Units through the
duplexed cables.
Duplex Connecting Cables
CS1D I/O Interface Units
CS1D I/O Control Units
Note If there are problems in both Connecting Cables, the system will stop.
Communication Unit settings must be made for both the primary and second-
ary Communications Unit. Refer to the operation manual for the Communica-
tions Units for information on the settings that are required.
In a CS1D Duplex CPU, Dual I/O Expansion System, it is possible to duplex
the Connecting Cables between the CPU Rack and Expansion Rack and the
Connecting Cables between Expansion Racks. The system components
required for duplex Connecting Cables are a CS1D-DPL02D Duplex Unit,
CS1D-BC042D CPU Backplane, CS1D-BI082D Expansion Backplanes,
CS1D-IC102D I/O Control Units, CS1D-II102D I/O Interface Units, and Duplex
CPU Units with unit version 1.3 or later.
A duplex Connecting Cable system can be configured by mounting two CS1D
I/O Control Units in the CPU Rack, mounting two CS1D I/O Interface Units in
each Expansion Rack, and connecting the Racks with two Connecting
Cables. In a PLC system with duplex Connecting Cables, data is simulta-
neously transferred over both cables between the CPU Unit and Units in the
Expansion Racks.
If one Connecting Cable is disconnected or damaged, data transfer will con-
tinue without interruption. When the Cable is reconnected or repaired, duplex
Connecting Cable operation will be restored.
Each Connecting Cable’s status can be checked with the flags in A270.
