Omron CS1W-DRM21, CJ1W-DRM21 operation manual DIP Switch, Baud Rate

Nomenclature and Functions		Section 2-1
Note	1. The node address is set to 63 at the factory.
	2.	Any node address from 0 through 63 can be set as long as it hasn’t been
		set on another slave node.
	3.	If the node address is the same as one set on another node, a node ad-
		dress duplication error will occur and it won’t be possible to start up net-
		work communications.
	4.	Node address 0 cannot be used for FINS message communication. Use a
		node address other than 0 for FINS message communication.
DIP Switch	The DIP switch on the front of the DeviceNet Unit is used to set the baud rate,
	whether communications will be continued or stopped when a communica-

tions error occurs, and whether to hold or clear the remote outputs when a communications error occurs in the slave function.

Continue/stop communications for communications error (when used as a master) Baud rate

The settings of the DIP switch pins are shown in the following table. All pins are set to OFF at the factory.

Pin	Function		Setting
1	Baud rate	See the next table.

3	Continue/stop remote I/O communica-	OFF:	Continue communications
	tions for communication errors (when	ON:	Stop communications
	used as a master)
4	Hold/clear remote outputs for commu-	OFF:	Clear remote outputs
	nications error (when used as a slave)	ON:	Hold remote outputs

Baud Rate

Pins 1 and 2 are used to set the baud rate as shown in the following table.

Pin 1	Pin 2	Baud rate
OFF	OFF	125 kbps
ON	OFF	250 kbps
OFF	ON	500 kbps
ON	ON	Not allowed.

Note 1. Always turn OFF the PC before changing the DIP switch settings.

2.Set the same baud rate on all of the nodes (Master and Slaves) in the Net- work. Any slaves with baud rates different from the master’s rate won’t be able to participate in communications and may cause a communications error between nodes that have been set properly.
