The data in the process image is updated as soon as the memory contents change. The data in the
process image is valid as soon as the status bit "Cmd End" is set.

8.5 "Auto-write data” operating mode
In the "Auto-write data" operating mode the data to be written is defined by the process data output
image. The data is set by the parameters "Auto-Read/Write Address" and "Auto-Read/Write Data
Length".
Max. 28 bytes can be defined in the process data output image (data 0 to 27). If a shorter length is
defined in the parameter "Auto-Read/Write Data Length", the other data bytes are ignored and not
written to the internal memory.
If writing was successful, the written data is copied to the process data input image and the status bit
"Cmd End" is set.
