The CN2DN module is designed to be mounted on a 35 mm steel DIN rail. End
anchors are provided to keep the module in position.
The device has one ControlNet port with support for redundant media as well as
a ControlNet network access port. Rotary switches are used to set the ControlNet
node address. The CNet Status LEDs display the current status of each of the
redundant media channels.
The CN2DN has one DeviceNet port. Rotary switches are used to set the
DeviceNet node address and the data rate. DNet LEDs display the current status
of the network and the I/O channel.
Module Status and Linking Activity LEDs are also provided. For information
about the LEDs, see “Interpreting the Status Indicators” beginning on page 27.
The power supply connector is wired to 24V dc.
