over messages from channel 1 to channel 2. This places all UR-series IEDs into one direct input and output network
regardless of the physical media of the two communication channels.
The following application examples illustrate the basic concepts for direct input and output configuration. See the Inputs
and Outputs section in this chapter for information on configuring FlexLogic operands (flags, bits) to be exchanged.
Example 1: Extending the input/output capabilities of a UR-series relay
Consider an application that requires additional quantities of contact inputs or output contacts or lines of programmable
logic that exceed the capabilities of a single UR-series chassis. The problem is solved by adding an extra UR-series IED,
such as the C30, to satisfy the additional input and output and programmable logic requirements. The two IEDs are
connected via single-channel digital communication cards as shown in the figure.
In this application, apply the following settings. For UR-series IED 1:
DIRECT OUTPUT DEVICE ID: "1"
DIRECT I/O CH1 RING CONFIGURATION: "Yes"
DIRECT I/O DATA RATE: "128 kbps"
For UR-series IED 2:
