Connectivity stops when i add a data point and return-back after i deleted it
-
Hello again!
I try to add (via modbus TCP connection) a point value.
In test locator show me the right value and seem to be ok.
When i choose "add point" and make the configuration of this, as a result in the watchlist, show me NOTHING and also block the connection with other-added-data points,with different addresses.Which reason could cause this bug in my connection, with this data point?
When i delete this the connection return back to normal for the others data points.
Thanks!

Hi Nikospps,
I'm not certain. Are you getting any events or log messages?
If I had to guess, there is an illegal address exception in your logs, and the actual modbus requests span your existing point and your new point, but in between in those addresses is one the device doesn't grant permission to read.
So, to fix, use the "Contiguous batches only" setting, or decrease your maximum register / bit request size until it stops happening.
