6Operating Modes
All the ejectors in this series can be operated in two operating modes:
• Via direct connection to inputs and outputs (standard I/O = SIO) or
• Connection via a communication line (IO-Link)
By default, the ejector always runs in SIO mode, but it can be switched in and out of IO-Link mode by an
IO-Link master at any time.
6.1SIO Operating Mode
In SIO mode, all input and output signals are connected to a controller, either directly or using intelligent
terminal boxes. For this purpose, in addition to the supply voltage, two input signals and one output sig-
nal should be connected to allow the ejector to communicate with the controller.
The following basic ejector functions are used:
• Inputs
– Suction ON/OFF
– Blow off ON/OFF
• Output
– H2 (Part Present) feedback
The “Blow off” signal does not have to be used if the ejector is operated with internal time control in
blow off mode. This allows operation on a single port in a configurable terminal box (using 1xDO and
1xDI).
The parameters are set and the internal counters are read out using the operating and display elements.
The energy and process control functions are unavailable in SIO mode.
6.2IO-Link Operating Mode
By default (after the supply voltage has been applied), the product always runs in digital I/O mode or SIO
mode, but can be switched to IO-Link mode at any time by an IO-Link master.
When operating the product in IO-Link mode (digital communication), the supply voltage, the ground
and the communication line are connected to a controller, either directly or using intelligent terminal
boxes. The communication line for IO-Link (C/Q line) is always connected with an IO-Link master port
(point-to-point connection). It is not possible to connect multiple C/Q lines to a single IO-Link master port.
Connecting the Ejector via IO-Link provides access to a number of additional functions alongside the basic
functions of the Ejector, such as suction, blow-off and feedback.
They include:
• The current vacuum level
• Choice of four production profiles (production setup profiles)
• Errors and warnings
• System status indicator
• Access to all parameters
• Energy and process control (EPC) functions
This allows all modifiable parameters to be read, modified and written back to the Ejector directly via the
higher-level controller.
Evaluation of the condition monitoring and energy monitoring results allows you to draw direct conclu-
sions regarding the current handling cycle and perform trend analyses.
The product supports IO-Link revision 1.1 with fifteen bytes of input data and four bytes of output data. It
is also compatible with IO-Link masters that use revision 1.0 and above. In this case, one byte of input
data and one byte of output data are supported.
