In the following cases, perform two successive teach actions:
• Analog output: teach the two positions for start and end of the analog value range
• Switching output: individually teach setpoints SP1 and SP2 in Window or Two-Point mode
Ä
Ensure that the taught values are taken over correctly, for example by checking the corresponding en-
tries in the configuration menu.
7.1.5
Teaching the output functions via the IO-Link system commands
A number of output functions can be taught via the IO-Link interface using system commands (see chapter
7.4 "IO-Link interface"). This chapter describes how to teach the analog output and the switching output
functions.
Teaching the analog output via IO-Link system commands
To configure the analog output, the two distance values
Position Min. Val.
and
Position Max. Val.
are
taught at which the respective minimum or maximum analog value is output.

Command
Description
0xC0 / 192
Teach Analog_Min
System command: AnalogRangeMin=TP
Teaches the distance value to which the lower
analog limit value (4 mA, 1 V, 0 V) is assigned
(
Position Min. Val
.).
0xC1 / 193
Teach Analog_Max
Teaches the distance value to which the upper
analog limit value (20 mA, 10 V) is assigned (
Po-
sition Max. Val
.).
Teaching-in the switching outputs via IO-Link system commands
The teach-in functions are compliant with the
Smart Sensor Profile
specification. Manufacturer-specific ex-
tensions are included with two of the three teach-in functions.

Detailed descriptions of the teach-in processes can be found in the

Procedure:
Ä
The so-called "setpoint" (1 and/or 2) is taught.
Ä
In the second step, the corresponding switching function is defined.
This means that setpoint "SP" is not yet the same as switching point "SSC". Via the switching function /
switching mode defined in the second step, the setpoints with the corresponding hystereses become
switching points.
If, for example, teaching is performed in Window mode, both setpoints (SP1 and SP2) are taught while re-
taining the distance to one another.
