Synchronization with the controller
In the case of synchronous transfer, both the controller and the HMI device set status bits in
the shared data compartment. You can use this mechanism to prevent unintentional
overwriting of data in either direction in your control program. You define the address range
of the data compartment separately for each controller on the "Range pointer" tab in the
"Connections" editor.
Applications for synchronous transfer of recipe data records:
• The controller is the "active partner" for the transfer of recipe data records.
• The controller evaluates the data containing the recipe number and name, as well as the
• Trigger the data record transfer with a system function or PLC job, e.g. with the system
In order to synchronize transfer of data records between the HMI device and the controller,
the following requirements must be met during configuration:
• The "Data mailbox" range pointer is located under "Range pointers" in the project view.
• The controller with which the HMI device synchronizes the data record transfer is

Scenario: Entering recipe data records in Runtime

Objective
You want to enter production data on the HMI device without disturbing the process that is
currently underway. Therefore, the production data should not be transferred to the PLC.
