Description
The "Stopped on Standby-Server" setting can be enabled for the MODRTU32 driver, however the setting is not stored correctly after closing the driver configuration dialog.
Solution
An issue was resolved that caused the "Stopped on Standby-Server" setting to not be stored correctly.
The MODRTU32 driver configuration dialog now stores the setting correctly when closing and reopening the dialog.
Information
The "Stopped on Standby-Server" setting can be used to provide driver redundancy for devices which allow only one communication connection.
If this option is enabled, the driver is stopped on the Standby Server and is only started at the Server change-over. Variables based on this driver do not receive the "switched off" status, but an empty value. This prevents irrelevent values being created in the AML, CEL and Historian modules during Server change-over.
