Dlms meter reading software11/1/2022 ![]() ![]()
Its often used for connecting to energy management systems or BMS. Logging pulses is prone to missing a pulse and you need to log a base meter reading you want to track the total meter reading. This is very useful for this kind of project! Reading the meter register is obviously a better way of monitoring the meter's consumption. Welcome to the forum! I didn't realise that the basic Elster meters automatically push out data through the IR port. These meter readers must be capable of reading from multiple manufacturers' meters - that and the fact that GuruX seem to have an open source product advertising such a capability leads me to believe it can be done. I think the Elster meters must be compliant with DLMS COSEM and it was possible to reverse engineer what much of the information comprised of - with documentation I think it could be relatively easy to modify.ĭLMS COSEM has different levels of what it allows - all we need is the equivalent of what the hand held meter readers have - to read consumption and some useful other information that seems to be broadcast. Reading through the experiences had by those in my earlier links, I'm optimistic that it is not a great leap to take it from Elster specific meter reading to something more general purpose. I would be very interested to hear how you get on with this. Theres plenty of Arduino projects using IR communication. To communicate directly to the meter's silicon over IR should be simple. You could always log the pulses at an SD card every 1 minute or 30 mins etc. ![]() #Dlms meter reading software serial#The code is simply an analogRead and triggers a serial transmission when a certain threshold is reached, i. Im measuring the time between each pulse and calculating a rate of energy consumption in kWh. Has anyone any thoughts or knowledge of the above? Hi, I have done something similar using a Nano with simple photoresistor to pick up when the red LED pulses on my home electric meter. I have a 3 phase meter the one in the example above is single phase and I have written to Elster asking them for more information around what they are broadcasting - we'll see what they come back with. I am particularly interested as I have an Elster meter which I understand transmits the information over IrDA once every second. I think that this is the way to go for ongoing and accurate meter reading. These next few links also cross refer I think but they are useful in getting an idea of what is possible. Most meters nowadays have a way in which to interface and obtain this information - often it is by an IrDA device located adjacent to or in the vicinity of the flashing LED used for the pulse counting. Using such a method would allow for the Arduino to poll when it wants information rather than having to use interrupts etc. I have seen a number of projects where an Arduino is used to read a flashing LED to allow consumption information to be compiled but very little about using DLMS COSEM protocols to read potentially more and also more reliably, actual cumulative consumption information at any moment in time. + deviceSerialNumber + '!

IEC62056-21 Handshake In serial port connection default IEC62056-21 settings are: Bitrate 300, 7E1. Some devices require IEC62056-21 protocol handshake before starting to communicate using DLMS protocol. Connection Initialization The connection initialization depends on the connection type and the device. The components, interfaces and methods are described more precisely later in this document. #Dlms meter reading software software#Our user-friendly software allows you to read meters which are connected to your computer, whether it be a PC (Windows XP+), Mac (OSX 10.5+), or Linux, and.Īt this moment we have libraries or components for ANSI C, ANSI C++.C#, Java and Delphi. #Dlms meter reading software drivers#Of custom software drivers Meter readings can be imported from. The Automatic Meter Reading solution is based on. With the component you can easily communicate between DLMS/COSEM devices, by using the data connection, and the manufacturer of your choice. ![]() Introduction Gurux DLMS/COSEM component is designed to simplify communication with DLMS/COSEM devices.
