Hi,

You try to connect with WRAPPER and your meter is operating using HDLC.
If you want to use WRAPPER you need to change TCP/IP port from 4060 to 4062.

Hi,

Create a new device. L&G is using Logical Name referencing. Check that it's checked.
Then Select Interface HDLC and port number: 4061. Then accept the changes and connect.

Hi,

You can write at the same was as you read data from the meter.
You need to change the access rights for higher if you want to write for the meter.
