node-red-contrib-trexmes-oee-calculator

This is a Node-Red is produced to provide instant calculation of OEE industrial values with the data coming from the IoBox serial communication hardware device used in Trex Mes systems. At the end of the production cycle time, instant Availability, Performance, Quality and OEE values are calculated and sent to the node output. A continuous data feed is required for calculations to be made. The expected input data should be as follows.

{
	stoppage: "0"
	working: "1"
	itemcount: "17"
	wasteitemcount: "3"
	interval: 15
	expecteditemcount: 6
}

Here stoppage : Digital (0 / 1) signal at the time of stop working : Digital (0 / 1) working signal from the machine itemcount : Total number of production instantly wasteitemcount : Instantly total waste production interval : Production Cycle time or production frequency to be calculated expecteditemcount : The expected production number within the entered cycle time.

Example output of the node.

{
    availability: "0.83",
    performance: "0.80",
    quality: "0.80",
    oee: "0.53"    
}
