2 Product Description
2.1 General description
The versions of the vacuum switch and pressure switch in the VSi series are referred to only
as the switch below.
The VSi-series switch can be operated in two operating modes. Users can choose between direct
connection to discrete inputs (standard I/O = SIO mode) or connection through the communication line
(IO link Class A).
Switching points are indicated using one or two orange LEDs. If the switching point is not active, the
operational readiness is indicated by a green LED.
Additionally, a multitude of information and status reports for the switch can be accessed using
wireless communication with NFC (Near Field Communication).
The parameters can also be set using two buttons on the display version (VSi-…-D). The current
system status and the settings are shown on a display.
The fluid connection offers the opportunity to align the switch in a screwed-in position.

4.3 IO-Link commissioning
When operating the switch in IO-link mode (digital communication), the supply voltage, Gnd and the
C/Q communication cable must be directly connected with the corresponding connectors of an IO-Link
master with Ports IO-Link Class A. When doing so, a new port must be used for each switch; a
junction of several C/Q cables is not possible with only one IO-Link master port.
The IO-Link master must be connected in the configuration of the automation system in the same way
as other fieldbus components. To activate the port for IO-link communication, a software tool from the
respective master manufacturer is usually provided (e.g. Siemens PCT Beckhoff TwinCAT, etc.). The
necessary device description data (IODD) for the switch can be downloaded from our website
www.schmalz.com.
The second output OUT2 for the switch is deactivated in IO-link operation.

5 Interfaces
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.

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.

INTERFACES
30.30.01.00956/01 www.schmalz.com EN | 17
5.2.1 Configuration server
Since revision 1.1, the IO-Link protocol has contained an automated process for transferring data
when a device is replaced. For this data storage mechanism, the IO-Link master mirrors all setting
parameters for the device in a separate non-volatile memory. When a device is swapped for a new
one of the same type, the setting parameters for the old device are automatically saved in the new
device by the master.
In order for this to work with the switch, it must be operated on a master with IO-Link revision 1.1 or
higher and the data storage feature must be activated in the configuration of the IO-Link port.
A detailed description of the data storage mechanism cannot be provided here; however, note the
following practical information:
To ensure that data is transferred in the correct direction when a device is replaced, it must be
ensured that the new device is restored to the factory settings before it is connected to the IO-
Link master.
This can be done at any time using the function for restoring the factory settings, for example,
via the operating menu.
The device parameters are automatically mirrored in the master when the device is configured
using an IO-Link configuration tool such as S7-PCT.
Changes to the parameters made in the user menu on the device or via NFC are automatically
mirrored in the master.
Changes to the parameters made by a PLC program using a function module are not
automatically mirrored in the master.
In this case, mirroring can be triggered manually by executing ISDU write access to the
“System Command” parameter (index 2) with the “ParamDownloadStore” command
(numerical value 5) once all the required parameters have been changed.
5.3 NFC
NFC (Near Field Communication) refers to a standard for wireless data transfer between different
devices over short distances.
The switch functions as a passive NFC tag which can be read by a reader, e.g. smart phone or tablet.
With the NFC applications by Schmalz, the information is displayed using a mobile website in the
browser, therefore an app is not required. The smartphone must only have NFC activated and be
connected to the internet.
Since the reading distance is very short, as is the case with other NFC applications, you should find
out about the position of the NFC antenna in the smartphone or tablet used. The following instructions
should be observed for an optimum data connection between the NFC reading device and VSi:
In the VSi version, the antenna is located behind the NFC label on the housing
In the VSi...D display version, the antenna is located directly behind the display
The mobile device itself must be aligned as parallel as possible to the front of the switch
The antenna of the mobile device should be positioned in the center of the antenna of the
switch
The NFC functionality is supported by many current smartphones. At the time of creating this
document, the situation with regard to Apple devices was that the NFC communication was not yet
available for general use such as for use by the Schmalz vacuum/pressure switch.
When parameters of the switch have to be changed via the IO-link or NFC, it must
be ensured that the power supply of the switch then remains stable for at least three
seconds. Otherwise, it can result in data loss and the subsequent error E01.
Access to the switch's parameters via NFC also works without a connected supply
voltage.

MANUAL OPERATION OF THE DISPLAY VERSION
18 | EN www.schmalz.com 30.30.01.00956/01
6 Manual operation of the display version
The switch is operated using the mode and set buttons. Settings are made using software menus. The
operating concept is set up according to VDMA 24574-1 and is divided into three menu levels:
Basic menu
Menu for additional functions (AF)
Info menu (INF)
Setting of the switch in the basic menu is sufficient for standard applications.
The display shows all of the information, including:
Actual vacuum/pressure measurement value
Selected menu item
Settings
Error messages
When switch parameters have to be changed in the operating menu, it must be
ensured that the power supply of the switch then remains stable for at least three
seconds. Otherwise it can result in data loss and the subsequent error E01.
6.1 Operating concept
6.1.1 Display of vacuum and pressure values
In the basic operating menu state, the actual measurement value is displayed on the basis of the
chosen display unit. All units are available in millibar, kilo pascal, inch-hg and PSi.

With version V, the vacuum value, i.e. the vacuum compared to the ambient air pressure, is displayed
as a positive; in version P10, it is displayed based on the pressure.

MANUAL OPERATION OF THE DISPLAY VERSION
30.30.01.00956/01 www.schmalz.com EN | 19
In version V8, the pressure is positive and vacuum is negative; however, the positive/negative sign is
not displayed. You can determine whether the value is positive or negative using the table due to the
presence of a decimal point.
The switching threshold SPx/FHx and rPx/FLx in the operating menu is displayed based on the same
method.
If an error status is active, it is indicated in the display through a periodic switch with the measurement
value. For recognition purposes, a prefix “E” stands for error, followed by the error number (see list in
chapter 8.1).
One exception is error 7 (operating voltage too low): in this case “E07” will be permanently indicated in
the display and the switch will delay further user entries until the operating voltage has reached the
necessary level again.
6.1.2 Navigating in the menu
The basic menu can be reached from the basic status by pressing the SET button.
To scroll through the menu press the SET button.
When the desired menu item has been found, select it using the MODE button.
If there is a submenu (“AF” and “INF”), this can also be browsed in the same manner using the SET
button.
By pressing both buttons at the same time, it is possible to quit the menu at any point.
6.1.3 Editing the parameters
If a menu item has been selected, the current value will firstly appear in the display. With parameters
that can be set, the whole value or lowest number will flash and can be changed by using the SET
button. When doing so, the possible settings are run through cyclically.
With version VP8, the values of the switching thresholds SPx/FHx and rPx/FLx can be positive
(pressure measurement range) as well as negative (vacuum measurement range). In this case, the
desired range of the new value is set at the start of the editing process. The text “PrS” for pressure or
“UAC” for vacuum will firstly flash and can be selected accordingly.
For numerical values that consist of three numbers, the MODE button can be changed for the next
higher number.
At the end of the editing process, the MODE button is pressed again after the last number. The new
value then appears for two seconds in the display without flashing.
If the new value is invalid, the display will instead receive a message and the old value is retained:
„Oor“ (out of range) means that the new value is generally out of range, for example, SP1> 8.0
bar in the variant VP8
„InC“ (inconsistent) means that the value collides with the current setting of another
parameter, e.g. rP1> SP1
To cancel the editing process, both buttons can be simultaneously pressed at any time.

operating menu, but generally last only a few seconds.
However, if editing is attempted at the same time using the menu, this will be
rejected with the display “LoC.”
