5.2.6 Teach-in procedures
General information
– Setpoint 2 (SP2) as per Smart Sensor profile is not supported for this sensor (always 0x0000).
– For the Single Value Teach applied here, both teach-in points (TP1 and TP2) are taught in at the same time and
are assigned the same value (the status bits are therefore not supported).
Preconditions
The sensor is mounted, aligned, and in IO-Link mode.
