The rotary switch is used to set the C200H I/O Link Unit's unit number
(Machine No.).
PLC
C200HX/HG-CPU5@/6@/8@ (-Z)
C200HX/HG-CPU3@/4@(-Z)
C200HE (-Z) all models
Provided the unit number is not being used by another Special I/O Unit
mounted to the same PLC, the settings can be made anywhere within the set-
ting range. Use a small flat-blade screw driver, and take care not to scratch
the rotary switch when making the setting.
1. Always turn OFF the PLC's power supply before changing the rotary
switch setting.
2. The unit number determines which words will be allocated to the Unit in the
Special I/O Area.
3. If the C200H I/O Link Unit and another Special I/O Unit mounted to the
same PLC have the same unit number, an error will occur on the PLC and
the Unit will not be able to participate in the DeviceNet Network.
4. When a C200H I/O Link Unit and a DeviceNet Master Unit are mounted to
the same PLC, set the C200H I/O Link Unit's unit number higher than the
Master Unit's unit number. When the C200H I/O Link Unit has a higher unit
number, it will recognize the Master Unit when the PLC is turned ON, so
you can set Read/Write Areas that do not overlap.
If the C200H I/O Link Unit is mistakenly given a lower unit number, the
Master Unit will recognize the C200H I/O Link Unit when the PLC is turned
ON and it will not be possible to use fixed allocation. In this case, you must
use the Configurator to customize the Master Unit's Input/Output Areas so
that they do not overlap with the C200H I/O Link Unit's areas.
