Can you please check from your end why this is not working in Wrapper Interface?

Thanks,

Hi Jigar,

WRAPPER is used with TCP/IP connections and HDLC is used with serial port connections. The meter accepts only HDLC frames in serial port connection and it can't handle WRAPPER frames so they are skipped.

Hi Mikko,

We have checked the same with connection with GXDLMSDirector, it's working properly.
GXDLMSDirector Tool --- Meter (Interface:Wrapper) - Working

But problem here is only with DLMS.c
DLMS.c --- Meter (Interface:Wrapper) - Not Working

DLMS.c should also work in same condition can we have such support in library?

Thanks,
Jigar

Hi Jigar,

GXDLMSDirector is using HDLC also for serial port connections even WRAPPER is selected.
This functionality was added because WRAPPER was causing a lot of problems with serial port connections.

Hi Mikko,

You mean to say that below configuration is not supported for serial port in DLMS.c right?

DLMS.c --- Meter (Interface:Wrapper) : Serial Port

Hi Jigar,

Your meter doesn't use WRAPPER framing with the serial port. It's using HDLC framing and you need to use the same framing or the communication doesn't work.

ANSI C is sending WRAPPER frames as you have asked, but the meter can't handle them and the communication fails.

Hi Mikko,

It seems that there is confusing in understanding my setup.
My meter is having two connection to communicate with meter and both are working as expected with GXDLMSDirector Tool.

Below is further clarification for my setup and ask

1. Optical Connection - works with HDLC frames
GXDLMSDirector Tool --- Meter (Interface:HDLC) - Working
DLMS.c --- Meter (Interface:HDLC) - Working

2. Serial Connection - works with Wrapper frames
GXDLMSDirector Tool --- Meter (Interface:Wrapper) - Working
DLMS.c --- Meter (Interface:Wrapper) - Not Working - Why?

Thus it seems that there is no problem in Meter but DLMS.c is not working for serial connection - Wrapper frames with meter.
It is unable to identify data from meter, here meter is sending data we have verified it on Saleae logic analyzer.

Thanks,
Jigar

Hi,

The reason is that GXDLMSDirector doesn't use WRAPPER for serial port connections.
It is using HDLC for serial port connection even WRAPPER is selected.

Your use case is using HDLC even though you have selected the WRAPPER.

2. Serial Connection - works with Wrapper frames
GXDLMSDirector Tool --- Meter (Interface:Wrapper)

If you check the send and received bytes that will start with 0x7E that is HDLC framing, not WRAPPER.

Mikko
