Test Intro CIM On Demand Meter Read Interoperability Test The ability to perform on-demand or on request meter reads is a basic interoperability requirement of utility systems. Systems tested include the Customer Information System (CIS), or similar system, and the Metering System (Head-End). Some configurations will relay the messages through the Meter Data Management System (MDMS) which can perform filtering functions. The On-Demand Meter Data Read Interoperability Test verifies that the MS returns the correct response CreatedMeterReadings message corresponding to the CreateMeterReadings request message. Actual meters, if available, may be used in the test system.

Test Description The ability to schedule meter reads from a CIS (or similar system) to an MDMS or Head End (or similar system) is validated for the systems under test. Standard IEC part 9 meter messages to/from the Meter Data Management System (MDMS) and from/to the Customer Information System (CIS) are used to 1) schedule meter reads for a specific time and 2) read meter usage and billing data for multiple meters. The MeterReadSchedule message is sent from the CIS/other system to the MDMS to request meter usage data for a scheduled meter read. The Universal Modeling Language (UML) content of the MeterReadSchedule message is shown above in Figure 3-1. The required IEC part 9 eXtensible Markup Language (XML) Schema Definition (XSD) is used to send the MeterReadSchedule message. The CreatedMeterReading is sent from the AMI meter/simulator to the MDMS and onto the CIS. The required IEC part 9 XSD is used to send the CreatedMeterReading message. See Appendix A for more details on the XSDs and to obtain a copy IEC Standard part 9 required for this test.

Record and save the content of the message. Using one of the message content verification methods in MV-02, verify the content and format of the transmitted MeterReadings message are in concurrence with the MeterReadings XSD. Record and save the content of the message. Pass/Fail
