5 General Description of Functions
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.
In the delivery state, the signal output OUT 1 is assigned the function switching point 1, parts control, and
the signal output OUT 2 is assigned the switching point 2, leakage monitoring. They are configured in the
EF menu (Extended Functions) via the associated menu items
0u1
and
0u2
.
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
The electrical signal outputs are adjustable with regard to the switching behavior on the device. In the EF
menu or via IO-Link, a choice can be made between the PNP and NPN signal types for each signal output.
The setting is independent of the version.
The vacuum switch is factory set to PNP.
5.2 IO-Link
The vacuum switch can be operated in IO-Link mode to enable intelligent communication with a con-
troller. The parameters of the vacuum switch can be set remotely using IO-Link mode.
The vacuum switch provides many additional functions besides the two switching 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 (known as ISDU parameters).
• Within the framework of the ISDU channel, all settings (e.g. switching point modes and delay times)
for the vacuum 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 ejector can be re-
trieved. It also provides memory for user-specific information, for example the installation or storage
site.
The following diagram shows the alignment of the 2 byte process input data for the vacuum switch.

Contents Measured value (14 bit) SP2 SP1
The bits SP1 and SP2 reflect the logical status of switching points 1 and 2.
The measured value is displayed as 14 bit unsigned vacuum in millibar (vacuum positive).
