All About Metering, meters, Energy Industry and Use of Energy.
I talk about meters, how they work, the measuring systems, the metering protocols, communication protocols and etc.
I also talk about how we can produce and save energy, and how we can help our future.

Initiating a connection in HDLC communication, the AARQ and AARE sections
In this Video I will be covering the basics of AARQ and AARE packets in HDLC communications. The association request and responses are the crucial parts in initiating a connection.
The AARQ (Association Request) packet is a crucial part of the DLMS communication process. It’s like the friendly handshake that happens when two devices-say, a smart meter and a monitoring platform-want to start chatting and the AARE (Association Response) packet is a critical component in the association establishment process in various communication protocols, particularly in metering systems. The AARE packet is sent by the server (or called application) in response to an AARQ (Association Request) packet sen...

Meter Optical Ports and Probes
Просмотров 1634 месяца назад
Communcating with the energy meters through optical ports and collecting consumption or configuring meter parameters has been a common way in many utility companies. Using optical heads facilitates this way of data communications thus solving many human errors.

Electricity meters are simply measurement devices which calculate our electricity consumption. They vary from different functions that they have to various shapes and types. in this video we will cover the brief history of these meters and their basic differences.
Initiating a connection in HDLC communication (SNRM)
Просмотров 1 тыс.7 месяцев назад
Communicating over HDLC protocol requires both parties to initiate a connection thus a virtual circuit over a network like TCP and then start transmitting data. Inthis video we will be covering the first part of connection initiation which is the exchange of SNRM packets.
How to Translate HDLC Packets in DLMS Communications
Просмотров 2,2 тыс.Год назад
HDLC stands for "high-level data link control" and is widely used in metering communication infrastructures. working with DLMS COSEM energy meters requires knowledge of the DLMS standard and its communication protocols. In this video we will cover the basic structure of a HDLC packet and how to translate it. We will translate a packet segment by segment and also via a third party application Gu...
Difference Between Connectionless & Connection-Oriented Services
Просмотров 2,3 тыс.Год назад
There are certain ways to establish connection between two network locations in a computer network. Connection-oriented and connectionless services are two types of communication services that use different approaches to transfer data between two entities. In this video we are going to cover the basics on these two approaches and their differences.
hi one doubt at 6:11 HDLC packet length=20 that is 32 in decimal but total packet is 35 bytes long why the difference ?
In the sample HDLC packet in video, the length byte 21 is in hexadecimal, which translates to decimal 33. The value 33 includes both the control and address fields, as well as any data fields. Given that the Gurux DLMS Translator shows the packet length as 20 it’s subtracting the control information and fields irrelevant to data, aligning with the Gurux software’s interpretation and internal processing of HDLC frames specifically for DLMS contexts.
Thank you
Excellent information. Hoping future videos willl include practical examples using Gurux Director. Waiting for the next Video.
Thanks a lot for watching this video. sure I will create more videos containing sample packets. I will be delighted to have your sample packets via email and include them in the video.
good information...
Thanks for watching 🙏🙏🙏
it's deep information on DLMS meter.. but can suggest how we make voltage cureent or power read frame for modbus of DLMS energy meter?
Thanks for watching. I am making a make a video on request types in DLMS and will be published soon
Informative videos
Thanks a lot
Very nice information After long search in google and youtube I'm find this video It's very informative for me Thnks bro...
Thanks a lot. it's nice of you.
Thank you for this video, very helpful content.
@@joeyAlibaba thank you for watching
I have 3 questions: 1) For connectionless communication, you said that the datagram will only have the receiver's address only, wouldn't it have the sender's address and any information required to help with the delivery/transmission of the datagram to the receiver like port number etc? 2) At the end you mentioned that receiver will request retransmission if the datagram hasn't been received by the receiver's device however wouldn't that be for connection oriented? I mean UDP doesn't request retransmission or do any error checking that is why it's unreliable. Maybe you meant IP? ( I am unsure for IP if it will request retransmission) but overall I thought retransmission will only be for connection-oriented since TCP is one of the protocols in use there. 3) Can we link this to the OSI model? Especially when some of the protocols like TCP are used in the Transport Layer and etc for other protocols.
Thanks for watching my video! here are your answers. 1. that is why it contaings the receiver's address. both communication types have addressing systems like TCP or UDP. for example when a receiver requests the data from a website, the server(sender) will send the wesite data to the receiver using the address that the receiver has provided in the request packet. the request packet can contain addressing data based on the network type and protocol. 2. internet is an example of a connectionless communication. it utilizes both udp and tcp. but have this in mind that these are the very base concepts of data netsorks. in reality there are many protocols and utilizations which benefit from each other's capabilities. being able to request retransmission for a certain packet is in some certain protocols which are a mized version of both types. 3. yes. many protocols like HDLC, or WRAPPER which are a Data link level protocol, utilize TCP communication protocol that is in transport level. as I said, all these protocols can be used in different levels and work together.
Thank you
You're welcome
Excellant Video. Thank you. Waiting for your next video
Thanks a lot
Great video, thanks! One of the best videos on this topic right now. Is there a way we could contact you?
Thanks a lot. yeah sure you can email me on mrmeter87@gmail.com
Nice work, thanks! You have manged to compress a lot of useful information in such a short video. If I understand correctly, before a meter can be queried using DLMS requests, the underlying HDLC connection must be explicitly established through some combination of discovery and negotiation..? It would be nice if you could cover that topic in some detail.
Thanks a lot. Yes HDLC is a connection-oriented communication in which a connection must be established before data is transmitted. I will surely make a video covering the connection and negotiation part of HDLC communication in detail. Thanks for watching the video. 🙏🙏

Its helpfull thanks man 🎉
Thanks a lot! appreciate it.
Thank you my friend :)
Thanks a million! 😉
Thank you, that was good information
Thanks a lot.
