Abstract: Techniques are disclosed for monitoring the consumption of a plurality of metered resources. The techniques involve receiving a KYZ pulse from a first utility meter, where the first utility meter is coupled to a source of one of the metered resources, and where the first utility meter outputs the KYZ pulse based on a predefined amount of metered resource being passed through the utility meter. A first counter is incremented, where the first counter is associated with the utility meter and stored in a memory.

Abstract: A programmable logic controller (PLC) protocol converter is disclosed that allows a supervisory control and data acquisition (SCADA) system to effectively communicate with a PLC device using a desired communications protocol, particularly in cases where the PLC device does not “speak” the desired communications protocol. A first thread may be configured to continually read PLC addresses, one at a time, using a communications protocol understood by the PLC device. The first thread may store the data values in the shared data array within program memory. Thus, the first thread exposes data from the PLC device, as specified in the configuration file. At the same time, a second thread may be configured to serve the data in the shared data array according to a second communications protocol, e.g., to the SCADA system.
