OPC client read values only with default scan class

Ignition
1

Hi,

I’am using Ignition 7.7.4 with Kepware OPC server 5.17.
When I use a different class than the default, values are no longer read respectively the value is still 0. Writing value into OPC server is OK, but in Ignition remains 0. It happens in both OPC UA or DA connection.
Ignition OPC server with non default scan class works without problems.

It seems like it is normal behavior of KEPserver in simulation mode.
