sercos
The 4-channel IO-Link master 750-657 is mapped in sercos via the sercos IO
profile ("Function Specific Profile IO" (FSP_IO)) and function group S-0-1507
"Complex Protocol" and makes available 24-byte process data via the fieldbus
parameters (IDN) in the input and output range.
The process data consists of 20 bytes user date and another 4 bytes control and
status information (see section 6 "Process Image" and is displayed in sercos as
follows:
