CQM1H-series Controller Link Units
Section 4-5
4-5-2
Node Addresses
Set the node address of each Unit in the Network using the rotary switch on
the front of the Unit. The node address is used to identify each node in the
Network.
The node address can be set to any value between 01 and 32.
Set the node address using a small flat-blade screwdriver, being careful not to
damage the rotary switches.
Note
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.
4-5-3
Baud Rates
Set the following pins for the baud rate setting (DIP switch).
Note
Always turn OFF the PLC’s power before setting the baud rate.
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
The factory default setting is shown in bold.
