23. CDCTypeI–ProtocolSpecic
Most test set operations are independent of the specic protocol being used and are described
in the non-protocol specic topics. The most common protocol specic activity is dening the
message structure for a particular RTU. This involves dening the number and types of points
(analog, digital, and accumulator) congured in the device (RTU, IED) under test. This information
enables the test set to issue the proper data scan request and to parse and correctly display
information in data response messages. The following sections will describe the protocol specic
considerations, if any, for Task and Exchange operational modes and, within those modes, any
communication mode (Line Monitor, Master Simulation, and RTU Simulation) protocol specic
considerations.
23.1. CDC Type I – Exchange Mode
For Exchange Mode, protocol specic tasks are editing Exchange Denition and setting RTU
address information.
23.1.1. CDCTypeI–EditExchangeDenition
Congure one or more Scan exchanges (Scan 1, Scan 2, and Scan 3) with device point
information. In the following example, the device conguration consists of 16 digital points and 8
Analog points, in that order. From the Exchange view, right-click on the line containing the Scan
1 exchange and select Edit Exchange Denition.
