Write accesses

Determines whether write access to process variables of this group in the communication component should be synchronous or asynchronous.

Setting	Description of the
Synchronisation	The variable server forwards a write request to the communication component and waits until the write request has been executed. Synchronous writing increases data consistency in the PLC, as the communication component executes this synchronous write request directly.
Asynchronous	The variable server sends a request to write a process variable value to the communication component. The write request is buffered here and executed after all previous asynchronous write requests have been processed.

Parameters for module:

• Variables

• Group
