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.

	NODE NO.
	X101
	X100
Item	Specifications
Setting method	2-digit decimal
Setting range	01 to 32 (default is 01)
Node	All nodes in the Network

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).

ON

BAUD RATE

SW1

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.

	Switch			Baud rate	Maximum
					transmission distance
	Pin 1		Pin 2
OFF		OFF		2 Mbps	500 m
ON		OFF		1 Mbps	800 m
OFF		ON		500 Kbps	1 km
ON		ON		Do not set.

Note The factory default setting is shown in bold.
