Gurux DLMS for Java

Hi Team,

I tried to read a meter using client 32 and stored the template file. But when I am trying to read from the stimulation it is giving error
TCP/IP connection established.

SEVERE: Service not allowed. Invocation counter is invalid.
TX: 00 01 00 01 00 20 00 03 D8 02 05
TCP/IP connection closed.

I updated the password and block key according to my requirement. but still facing the above problem.

Hi,

You need to read the invocation counter (frame counter) from the meter. Add -v argument. I don't know the logical name of frame counter data object, but you can find it from the data objects.

Tou need to add argument like this:
-v 0.0.43.1.1.255

Hi Mikko,
Thanks for the reply. but I need clarification, this meter supports HDLC for serial communication and I created a template using the same communication. But while TCP supports the Wrapper interface. can we use the HDLC template file for the reading through the stimulator? or what changes we require to read through stimulator.

Hi,

After the template is created you can start the simulator -w argument. Now the WRAPPER interface is used and you can establish the connection for the simulator using the WRAPPER.
