Visualisation stops under certain circumstances

Thought I would post an issue for the benefit of others.

I have discovered painfully that when using Modbus devices, if any registers are mapped to objects (User Variables) which are used in Visualisation, and for some reason the register returns a zero value, the entire Visualisation stops working completely.

This occurs until the value into the User Variable becomes non-zero (which you can't manually override if polling is occuring since the Modbus driver overrides the value).

I have logged this issue, since it is causing us problems when a modbus device (we are using temp sensors in some buildings) has a problem and we cannot see anything since Visualisation is not available at all.

Hoping this can be rectified in a very near future firmware update.

Strange that any other objects (such as CBus devices) being zero does not have any impact on Visualisation.
