5 Noncyclical data exchange
To implement the exchange of program memories, you must take the following steps:
• Declare 1 data structure in the "Program data transfer" format (partial data records of a program
memory to be transferred) for both the outgoing and the incoming direction.
• Declare 1 data structure in the "Editing memory" format (total data of the program memory to be
transferred) for both the outgoing and the incoming direction.
• Program a sequence control for the data exchange sequence.
The procedure is described below.
