Network cabling

The C200HW-CORT21 can be mounted to the CPU Rack or Expansion I/O
Rack of any CS1, C200HX, -HG, or -HE PLC. Refer to the PLC's Operation
Manuals for details on mounting Units.
There are some limitations on mounting the Unit.
•
The current consumption of all Units mounted on one backplane should
not exceed the maximum output of the power supply. The C200HW-
CORT21 consumes up to 250 mA from the 5V supply. Verify the
characteristics of all other Units on their respective Instruction Sheets.
•
The C200HW-CORT21 is a Special I/O Unit. It can be mounted in any
slot in the backplane of a CPU Rack or Expansion I/O Rack as long as
its Unit number is not the same as the Unit number of another Special
I/O Unit within the system.
•
The maximum number of Special I/O Units that can be mounted depends
on the PLC CPU type.
•
For details on CS1-series PLC compatibility, see Appendix A.

All devices are connected in a bus structure (i.e. line). The wiring topology of
a CAN network should be as close as possible to a single line structure in
order to avoid cable-reflected waves. Stub-lines should be kept as short as
possible and must be less than 30 cm at the highest baud rate (1 Mbit/s).
