In the following cases, module or network status is displayed by combined indications
of this LED and the module status and network status LEDs.
• A trouble has occurred on the DN611 or on the network.
• An error has occurred due to a request from the S controller.
(Parameter setting, operation mode, etc. are controlled as requested by the S
controller.)
• The DN611 has run down.
See 6.2 Indications of the 7-Segment LED for the combined indications and
meanings of this LED and the module status and network status LEDs.
(3) DIP switches for operation mode/communication rate setting
These DIP switches are used for setting the DN611 in run mode in the event of a
busoff and a communication rate on the network (500 kbps/250 kbps, 125 kbps).
The meanings of the DIP switches and the method of their setting are described in
3.2 Setting the Switches.
(4) Rotary switches for node address setting (NA-H/NA-L)
These switches are used for setting node addresses in a DeviceNet network to which
DN611s are connected.
A DN611 can have a node address within the range of 0 to 63 (decimals) unless it is
identical with that of another node (slave device) on the network.
The method of setting the rotary switches is described in 3.2 Setting the Switches.
(5) Test connector
This connector is for maintenance only. You may not use it.
(6) Device connector (for DeviceNet connection)
This connector is for connecting DeviceNet cables to the DN611. The method of
connecting cables is described in 3.4 Connection to the Network.
