Baud Rate
Pins 1 and 2 are used to set the baud rate as shown in the following table.
Precautions for Safe Use
Always turn OFF the Controller before changing the unit number setting.
Precautions for Correct Use
Precautions for Correct Use
Set the same baud rate on all of the nodes (Master and Slaves) in the Network. Any slaves with
baud rates different from the master's rate will not be able to participate in communications and
may cause a communications error between nodes that have been set properly.
z
Continue/Stop Remote I/O Communications
If "stop remote I/O communication upon communication error" is set (turned ON) by DIP switch 3,
remote I/O communication will stop (*) when any of the following error occurs and will remain
stopped after the error is reset (message and slave communications will not stop).
•
*_Mstr1IOErr
(Remote I/O Communication Error)
•
*_SendTimeoutErr
(Send Timeout Error)
•
*_NetPwrErr
(Network Power Error)
To resume communications, change
*_ Sw1IOCommStartCmd
(Remote I/O Communications Start
Switch) of software switch 1 to TRUE. Refer to
3-2 Device Variables for CJ-series Unit (Software
for details.
Note
The 7-segment indicator will show "A0" when remote I/O communications stop.
If pin 3 is OFF, remote I/O communications will stop if a send timeout or network power error occurs,
but will restart automatically when the cause of the error is cleared.
z
Hold/Clear Remote Outputs
When the DeviceNet Unit is used as a slave, pin 4 is used to set whether to hold or clear remote out-
puts when a communications error occurs.
Note
If the DeviceNet Unit is used as a slave, the 7-segment indicator will show "L9" when remote
I/O communications stop.
