9.1 Process data
The FTL3x devices can be configured with one or two switch outputs. The status of the switch
output is transmitted in the form of process data via IO-Link.
• In the SIO mode, switch output 1 is switched at pin 4 on the M12 plug. In the IO-Link
communication mode, this pin is reserved exclusively for communication.
• The device's process data are transmitted cyclically in 16-bit chunks.

Bit 14 and bit 15 indicate the status of the switch outputs.
