Gurux.DLMS

Hi,
I'm trying to execute a script from a script table using Python, the code I use is the following:

scriptTable = GXDLMSScriptTable("1.1.1.128.0.255")
script = GXDLMSScript()
script.id = 1
scriptTable.execute(client, script)

And I get the error:
AttributeError: 'GXDLMSScript' object has no attribute 'getId'

As far as I can see in the class definition it's true that there is no getId method:

Maybe I'm doing something else wrong?

Hi,

You are right. I created an issue from this:
https://www.gurux.fi/node/19972

The new version is released today as this is tested.

Hi,

Before the release you can use it like this:

scriptTable = GXDLMSScriptTable("1.1.1.128.0.255")
script = GXDLMSScript()
script.id = 1
scriptTable.execute(client, script.id)

I tried and I can't get it to work, I also tried the client.method() and didn't work either.
I'm thinking that maybe I have not configured the client correctly.
The DLMS command line is:
-h 192.168.1.54 -p 10004 -c 17 -a Low -P Password -w 1 -f 128 -t Verbose
In the code I configured as follow:
client = GXDLMSSecureClient(forAuthentication=Authentication.LOW)
client.useLogicalNameReferencing = True
client.clientAddress = 0x11
client.serverAddress =GXDLMSClient.getServerAddress(0,1)
client.password = 'Password '
client.interfaceType = InterfaceType.HDLC
client.ciphering.security = Security.NONE

It seems to be working because I can read and write data and read registers, but the script execution don't work and don't gives me any trace either so I'm a bit lost. Do you have any idea?

Hi,
Reading the dlms package after the execute seems to fix it.
I'll let the code here in case someone have the same doubt.
I use the reader class from the client example.
scriptTable = GXDLMSScriptTable("1.1.1.128.0.255")
script = GXDLMSScript()
script.id = 1
data = scriptTable.execute(self.client, script.id)
reader.readDLMSPacket(data)

Hi,

Yes, if you don't call readDLMSPacket the generated frame is not sent for the meter.
I'm glad that it's working now.

hi mikko ,

how this implemented in c code.
and i dont know the command line parameter for this script id.

My CLI parameters are:-

-h 2401:4900:4022:f9e4::2 -p 9083 -i HDLC -c 1 -a HighGmac -C AuthenticationEncryption -T 5753453030303031 -A AE90F90883AC70AF5BCE9D8060EE22F0 -B 22C8DA0AA7BBE7918F57296C4BE9FA23 -o Output.txt -v 0.0.43.1.0.255 -g 0.0.10.0.1.255:2

Hi,

You can use those command line arguments with the ANSI C client example.

The client example only reads the data from the meter and you need to expand the client example to execute the script table as you wish.
