Overview

The ANSI X3.28/SRIO DPA software is installed in GE Energy Services WESDAC equipment to provide an interface to master stations using the ANSI X3.28 communication protocol.

Product Perspective

The ANSI X3.28/SRIO DPA software is custom software that will be installed in the GE Energy Services RTU to provide a communication link to master stations using the ANSI X3.28 communication protocol. The ANSI X3.28/SRIO DPA does not follow typical GE Energy Services DPA conventions, and interfaces directly to the SPABUS DCA.

The SPABUS DCA provides the only interface between the ANSI X3.2/SRIO DPA and WIN, and must be present in the system in order to use the ANSI X3.28/SRIO DPA. The DPA does not have access to the system WESDAC data tables, but only to data owned by the SPABUS DCA. The ANSI X3.28/SRIO DPA configuration tables reference the SPABUS configuration item table rather than the WESDAC tables. Figure 1 represents a complete system overview of how the DPA interfaces with the SPABUS DCA in a typical GE Energy Services RTU.
