Process image
The size of the process image can be set from firmware 04 onwards.
This chapter describes the process image in the factory setting. It contains 22 bytes of receive data and 22 bytes of send data.
Among other things, the size of the process image determines the maximum continuous data transfer rate. If your application requires a higher data transfer rate, you can set the size of the process image from firmware 04 onwards.
