Landys gyr e650 by IEC62056-21

Hi, I'm wondering if I can read this particular meter(Landys gyr e650) using only IEC62056-21 protocol mechanisms. I have my meter connected to the serial port via rs232 interface and what I'm trying to do is to get identification message after sending the standard IEC request, that is: "/?!\r\n" but I wasn't able to get any response whatsoever yet. I wanted to ask if anyone tried to do that and can tell me what port configuration should I use(baudrate, bits etc) or if this is even possible.

Thanks in advance
Mateusz

Hi,

If you really want to read your meter with IEC62056-21 try to set serial port settings:
Baudrate: 300 7Even1.

You can configure the start settings, so they can be anything.
If that is not working try:
9600 8Even1.

Unfortunately it's not

Unfortunately it's not working. Is there any way to check those settings outside of a software or written application?

Hi,

If a meter is not replying reason is usually on the cable. Are you using USB to RS-232 converter or are you using Optical head?

It is connected with rs232 to

It is connected with rs232 to rj11 cable. I have my own device(let's call it management station) built and tested with other meters such as ISKRA mt174 and ELSTER a1500 connected to rs485 interfaces of my device and these are responding correctly. Only Landys is causing me trouble.

Hi,

It might be that DLMS is set to priority protocol. Try to connect with GXDLMSDirector.
Use 9600 8N1. Set Start Protocol to DLMS.

In that case, is there any

In that case, is there any way to change that setting e.g. using only buttons on the meter because my built device doesn't have any graphical interface therefore using any kind of GUI application such as GXDLMSDirector is unfortunately not an option here.

Hi,

Yes, but you can try to connect from your PC and check is this the reason.
The reason might be anything and we need to block reasons one at the time.

I have my own implementation

I have my own implementation of dlms protocol which is working with this meter, so it's not like there's a problem with cable, connection or something. This priority setting might be the clue here.
