5.1 Digital switching outputs (SIO)
To operate the standard digital inputs of the automation technology or to directly control the electrical
consumers, the switch has two digital outputs.
The electrical status of both of the outputs OUT1 and OUT2 thus corresponds with the logical status of
switching points 1 and 2 regardless of the switching point parameters that have been set:
 Switching point mode and switching point logic
 Switching thresholds and hysteresis (function depends on mode set)
 Switch-on and switch-off delay times
 Electrical transistor functions PNP or NPN
5.2 IO-Link
The switch provides many additional functions besides both switch signals via the IO-link
communication.
 The actual measurement value is provided live using the process data
 Warnings and error statuses that occur are reported to the master via the IO-link event
mechanism.
 More precise information regarding the system status is retrieved using the acyclical
communication channel (so-called ISDU parameters).
 Within the framework of the ISDU channel, all settings (e.g. switching point modes and delay
times) for the switch are read or overwritten.
 In addition to the identification data that can be accessed from the control menu such as the
part number and serial number, additional information regarding the identity of the switch can
be retrieved.
The switch also provides memory for user-specific information, which means that, for example,
it is possible to save an installation or storage site.
The following diagram shows the alignment of the 2 byte process input data for the switch.

Measured value (14 bit)
SP2
SP1
The SP1 and SP2 bits reflect the logical status of switching points 1 and 2.
Depending on the version, the measurement value is displayed as follows:
 VSi V: 14 bit unsigned vacuum in millibar (vacuum positive)
 VSi P10: 14 bit unsigned pressure in millibar (pressure positive)
 VSi VP8: 14 bit signed pressure in millibar (pressure positive, vacuum negative)
A detailed description of all device parameters can be found in the data dictionary for the switch, which
can be downloaded together with the IODD as a ZIP archive from www.schmalz.com.
