Node
Set the node address using a small flat-blade screwdriver, being careful not to
damage the rotary switches.
1. Always turn OFF the PLC's power before setting the node address.
2. Do not set the same node address twice within the same Network. An error
will occur if the same address is set for two different nodes. The ERC indi-
cator on the front of the Unit will light and either communications will stop,
or the INS indicator will not light and you will be unable to participate in the
Network.
3. The send sequence for the data link areas is determined according to the
sequence of node addresses for automatically set data links.
4. Assign node addresses consecutively beginning from 01 whenever possi-
ble to minimize Network construction time.
Set the following pins for the baud rate and operating level settings (DIP
switch).
SW1
ON
Note: The factory default settings are shown above.
1. Always turn OFF the PLC's power before setting the baud rate or operating
level.
2. Keep pin 3 set to OFF. If it is turned ON, internal data may be erased.
Set the same baud rate for all the nodes on the Network using DIP switch pins
1 and 2 on the front of the Unit. The baud rate is set as shown below.
The maximum transmission distance will also change according to the setting.

Note Set the same baud rate for all the nodes on the Network. Normal communica-
tion cannot be performed unless the same baud rate is set for all the nodes.
With C200HX/HG/HE PLCs, Networks can be constructed by mounting up to
two Communications Units, such as Controller Link Units, SYSMAC LINK
Units and SYSMAC NET Link Units for the same PLC Each of these Units
must run on a different operating level.
Set the Controller Link Unit to operating level 1 or 0 using DIP switch pin 4 on
the front of the Unit.
