Limiting peak demand with IF-THEN rules on a power meter concentrator
How demand is measured, how to build staged load-shedding rules on a PMC or PMD concentrator, and a worked example with relay outputs.
Applications and know-how

Application guides for ICP DAS I/O, controllers, gateways and meters, sorted by the job they do.
ICP DAS makes the building blocks of measurement and control systems: remote I/O modules, programmable automation controllers (PACs), protocol gateways, power meters, sensors and IIoT edge devices. Most of them use open protocols such as Modbus RTU, Modbus TCP, MQTT and OPC UA, so they combine with each other and with PLCs, SCADA, building management systems and cloud platforms from other vendors.
The pages below are organised by application rather than by product line. Each one describes what a typical system in that area needs, which ICP DAS product groups fit, and what to check before you choose hardware. Articles with worked examples and selection guides are added to each area over time.
