Operating Modes
6 Operating Modes
All the ejectors in the SCPSi 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 signal 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
– Feedback 2 (“Part Present” check)
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
When operating the ejector 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-topoint connection). It is not possible to connect multiple C/Q lines to a single IO-Link master port.
Connecting the ejector via the IO-Link provides access to a number of additional ejector functions alongside the basic functions of suction, blow off, feedback, etc. They include:
• The current vacuum level
• Selection of four production profiles
• Errors and warnings
• Ejector system status display
• Access to all parameters
• Functions for energy and process control
So that all the modifiable parameters can be read directly via the higher-level controller, modified and written back to the ejector.
Evaluation of the condition monitoring and energy monitoring results allows you to draw direct conclusions regarding the current handling cycle and perform trend analysis. The ejector supports the IO-Link revision 1.1 with four bytes of input data and two bytes of output data. It is also compatible with IO-Link masters that use the 1.0 revision. In this case, one byte of input data and one byte of output data are supported. The exchange of process data between the IO-Link master and the ejector is cyclical. Parameter data (acyclical data) is exchanged by the user program in the control unit using communication modules.
EN-US · 30.30.01.01484 · 00 · 01/21 21 / 72
Operating Modes
6.2.1 Process Data
The cyclical process data is used to control the ejectors and receive current information reported from the ejector. There is a difference between the input data (Process Data In) and the controlling output data
(Process Data Out).
The input data Process Data In is used to report the following information cyclically:
• Vacuum limit values H1 and H2
• CM-Autoset acknowledgment
• EPC-Select acknowledgment
• The ejector device status in the form of a status traffic light
• Multifunctional EPC values
The output data Process Data Out is used to control the ejector cyclically:
• Vacuum on/off
• Blow off active
• Setup mode
• CM Autoset
• EPC-Select: switching the multifunctional EPC values
• Switching production setup profiles P0–P3
• Inlet pressure in 0.1 bar (measured value from external pressure sensor, 0 = function inactive)
A detailed description of the process data can be found in the data dictionary.
The corresponding device description file (IODD) is available for integration into a higher-level control unit.
6.2.2 Parameter Data
In addition to the process data that is exchanged automatically, the IO-Link protocol provides an acyclical data channel for identification data, setting parameters or general feedback from the device. The available data objects are referred to as ISDU with IO-Link and are to be uniquely addressed within a device through their index and subindex.
Controller manufacturers usually provide a specialized function module – e.g. the “IOL_CALL” module for
Siemens controllers – to enable these parameters to be accessed from a control program.
Information about which parameter data the device provides and how this data is displayed as ISDU objects can be found in the “Data Dictionary”.
6.2.3 IO-Link
The ejector can be operated in IO-Link mode to enable intelligent communication with a controller. The ejector’s parameters can be set remotely using IO-Link mode. The energy and process control (EPC) function is also available in IO-Link mode. It is divided into 3 modules:
• Condition monitoring (CM): Condition monitoring to increase system availability
• Energy monitoring (EM): Energy monitoring to optimize the vacuum system’s energy consumption
• Predictive maintenance (PM): Predictive maintenance to increase the performance and quality of the gripping systems

7 General Description of Functions
7.1 Picking up the Workpiece (Vacuum Generation)
The ejector is designed for handling and holding workpieces by means of a vacuum in combination with suction systems. The vacuum is generated in a nozzle according to the Venturi principle, using suction generated by the flow of accelerated compressed air. Compressed air is channeled into the ejector and flows through the nozzle. A vacuum is generated immediately downstream of the motive nozzle; this causes the air to be sucked through the vacuum connection. The air and compressed air that have been removed by the suction exit together via the silencer.
The venturi nozzle on the ejector is activated and deactivated using the suction command:
• In the NO (normally open) variant, the venturi nozzle is deactivated when the suction signal is received.
• In the NC (normally closed) variant, the venturi nozzle is activated when the suction signal is received.
An integrated sensor records the vacuum generated by the venturi nozzle. The exact vacuum level is shown on the display and can be read from the IO-Link process data.

Vacuum on Time [s]
The ejector has an integrated air saving function and automatically regulates the vacuum in suction mode:
• The electronics switch the venturi nozzle off as soon as the set vacuum limit value (switching point
H1) is reached.
• When objects with airtight surfaces are picked up, the integrated non-return valve prevents the vacuum from dropping.
• If the system vacuum drops below the limit value switching point H1-h1 due to leaks, the venturi nozzle is switched back on.
• Depending on the vacuum, the H2 process data bit is set once a workpiece is picked up safely. This enables the further handling process.
7.2 Depositing the Workpiece (Blowing Off)
In blow off mode, the vacuum circuit of the ejector is supplied with compressed air. This ensures that the vacuum drops quickly, allowing the workpiece to be deposited quickly.
The ejector provides three blow off modes for selection:
• Externally controlled blow off
• Internally time-controlled blow off
EN-US · 30.30.01.01484 · 00 · 01/21 23 / 72
General Description of Functions
• Externally time-controlled blow off
The current process state is indicated by the LED status indicators.
During blow off, [ -FF ] is shown on the display.
7.3 Operating Modes
The ejector can be operated in four operating modes:
• Direct connection to inputs and outputs (standard I/O = SIO)
• Connection via the communication line (IO-Link)
• “Manual mode,” operation using the ejector buttons
• Setup mode
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.
If the ejector is connected to the supply voltage, it is in automatic mode and ready for operation. This is the normal operating mode, in which the ejector is operated by the system controller. A differentiation is made between SIO mode and IO-Link mode.
The ejector is always parameterized in automatic mode.
7.3.1 Automatic Operation
Once the ejector is connected to the power supply, it is ready for operation and enters automatic operation mode. This is the normal operating mode, in which the ejector is operated by the system controller.
The operating mode may be changed from automatic to manual mode using the buttons.
The ejector is always parameterized in automatic mode.
7.3.2 Manual Operating Mode
WARNING
Through an external signal, manual operation is exited, external signals are evaluated and system parts move.
Personal injury or damage to property due to collisions
4 Ensure that the danger zone of the system is clear of people during operation.
4 Wear the required personal protective equipment (PPE) when working in the danger zone.
WARNING
Falling objects due to incorrect operation in manual mode
Risk of injury
4 Higher level of attention
4 Ensure that there are no persons within the danger zones of the machine/system
In manual mode, a higher level of attention is advisable because incorrect operation may cause gripped parts to fall, resulting in injuries.
In manual mode, the “suction” and “blow off” ejector functions can be controlled independently of the higher-level controller using the buttons on the operating panel. In this operating mode, the “H1” and
“H2” LEDs both flash. Because the valve protection function is deactivated in manual mode, this function can be used to locate and rectify leaks in the vacuum circuit.

General Description of Functions
Activating the Operating Mode
Press and hold the or button for more than 3 seconds. An M appears on the display while you do so.
The current process state is retained.
Manual suction
The button activates “suction” on the ejector.
Press the or button to exit the “suction” operating state again.
Manual blow off
The button activates “blow off” on the ejector for as long as the button is pressed.
Deactivating the Operating Mode
Using the button or through an external state change by signal inputs.
The valve protection function is not active in manual mode.
7.3.3 Setup Mode
Setting mode is used for locating and eliminating leakages in the vacuum circuit. Since the valve protection function is deactivated and the control is not deactivated, even at increased control frequencies.
In this operating mode, the “H1” and “H2” LEDs both flash.
Setting Mode Activated and Deactivated
4 Set the corresponding value using bit 2 in the output process data byte (PDO).
A change to bit 0 or bit 1 (suction or blow off) in the PDO also causes the ejector to exit setting mode.
This function is only available in IO-Link mode.
7.4 Vacuum Monitoring
The ejector has an integrated sensor for monitoring the current system vacuum. The vacuum level provides information about the process and has an effect on the following signals and parameters:
• The limit value H1
• The limit value H2
• The signal output H2
• The process data bit H1
• The process data bit H2
The limit values and associated hysteresis values are adjusted in the menu items x-1 , h-1 , x-2 and h-2
in the main menu or via IO-Link.
7.5 Control Function
The ejector allows you to conserve compressed air or prevent an excessive vacuum from being generated.
Vacuum generation is interrupted when the set vacuum limit value H1 is reached. If leakage causes the vacuum to fall below the hysteresis limit value (H1-h1), vacuum generation resumes.
The operating modes for the control function can be set under the [ ctr ] menu item in the configuration menu or via IO-Link.

General Description of Functions
Operating mode
No control/continuous suction, H1 in hysteresis mode
[ ctr
] => [ oFF
]
Control function activated
[ ctr ] => [ on ]
Explanation
The ejector produces continuous suction with maximum power. This setting is recommended for very porous workpieces, which would otherwise cause vacuum generation to switch on and off continuously due to the high rate of leakage. The limit value evaluation for H1 is operated in hysteresis mode.
Can be adjusted only if the control shutoff is deactivated
([ dC5
] => [ oFF
])
The ejector switches off vacuum generation when the vacuum limit value H1 is reached. It switches it back on when the vacuum falls below the hysteresis limit value
(H1-h1). The limit value evaluation for H1 follows the control function. To protect the ejector, valve switching frequency monitoring is activated in this operating mode. If the readjustment is too fast, the control function is deactivated and the device switches to continuous suction.
Control function activated, leakage measurement activated
[ ctr
] => [ on5
]
Like the “Control function activated” operating mode; in addition, the system leakage rate is measured and compared to the adjustable leakage limit value [
-L-
]. If the actual leakage rate exceeds the limit value more than twice in succession, the control function is deactivated and the ejector switches to continuous suction.
Available control function operating modes
The control shutoff function can deactivate the automatic control shutoff.
The function can be set under the [ dC5
] menu item in the configuration menu or via IO-Link. If the
[ dC5
= oFF
] function is selected, the ejector switches to the “Continuous suction” operating mode when there is excessively high leakage and the valve switches too frequently. With the [ dC5 = on ] setting, continuous suction is deactivated, and the ejector continues in control mode despite a high leakage rate or control frequency greater than 6 times per 3 s.
In the event of undervoltage or a power failure, the NO ejector version reacts with continuous suction even though continuous suction is deactivated with [ dC5
= on
].
7.6 Blow off Functions
The ejector has three blow off functions in three different modes. The function is set under the [ blo
] menu item in the configuration menu or via IO-Link.
Explanations of the blow off modes:
Description
Externally controlled blow off
[ bL0
] => [
-E-
]
Internally time-controlled blow off
[ bLo ] => [ l-t ]
Externally time-controlled blow off
[ bLo ] => [ E-t ]
Explanation
The ejector switches to blow off mode for as long as the blow off signal is present.
The blow off signal is given priority over the suction signal.
After the suction signal is switched off, the ejector switches to blow off mode automatically for the set time (which can be adjusted using
[ tbL ]). With this function, the blow off signal does not have to be additionally controlled.
The blow off signal overrides the suction signal, even if the specified blow off time is very long.
The blow off starts with the blow off signal and is performed for the set time period [ tbL
]. Applying the blow off signal for a longer time does not lead to a longer blow off period.

General Description of Functions
Description Explanation
The blow off signal overrides the suction signal, even if the specified blow off time is very long.
The length of the blow off time [ tbL ] is set in the main menu. This menu item is suppressed in operating mode [
-E-
].
The number displayed indicates the blow off time in seconds. Blow off times from 0.10 seconds to
9.99 seconds can be set.
7.7 Changing the Blow-Off Flow Rate on the Ejector
Do not overwind the stop on the valve screw. A minimum flow rate of approx. 15 % is always necessary for technical reasons. The blow-off volume flow can be set between 15 % and
100 %.
There is a valve screw below the vacuum connection that can be used to adjust the blow-off flow rate.
The valve screw is equipped with a stop on both sides.

+
1. Turn the valve screw clockwise to reduce the flow rate.
2. Turn the valve screw counterclockwise to increase the flow rate.
7.8 Monitoring the Supply Voltages
The ejector is not a voltage meter! However, the measured values and the system responses derived from them provide a helpful diagnostics tool for condition monitoring.
The ejector measures the supply voltages U
S
. The measured value can be read from the parameter data.
If the voltages are outside the valid range (min. 19.2 V and max. 26.4 V), the following status messages change:
• Device status
• Condition monitoring parameter
• An IO-Link event is generated
There is no guarantee that the ejector will operate as intended below a supply voltage of 19.2 V:
• The reaction to signal inputs is disabled.
• The “Part Present” check output retains its normal functionality.
• The current supply voltage can still be viewed using the button.
EN-US · 30.30.01.01484 · 00 · 01/21 27 / 72
General Description of Functions
• The pneumatic state of the ejector changes as follows:
– For the NO-type ejector, the ejector switches to the “suction” operating state
– For the NC-type ejector, the ejector switches to the “pneumatically OFF” operating state
7.9 Evaluating the Inlet Pressure
The available supply pressure level in the system cannot be measured by the ejector itself. However, the current measured value for the inlet pressure can be transmitted to the ejector from the system controller via IO-Link. In this case, the ejector evaluates the pressure level and activates a condition monitoring warning if the pressure level is not optimal. If there is a significant deviation, an error message is also generated.
A pressure level must also be transferred to enable the volume of compressed air consumed in the suction cycle to be estimated in the area of energy monitoring.
7.10 Calibrating the Vacuum Sensor
As the production conditions for the internally integrated vacuum sensor can vary, we recommend calibrating the sensor once it is installed in the ejector. To calibrate the vacuum sensor, the system's vacuum circuit must be open to the atmosphere.
The function for zero-point adjustment of the sensor is performed in the main menu under the parameter
CAL
or using IO-Link.
1. Press the button
ð The menu changes to input
2. Press the or button until cal appears on the display
3. Confirm with the button
4. When
YE5
appears, press the button to confirm.
ð The vacuum sensor is now calibrated.
A zero offset is only possible in the range of ± 3% around the theoretical zero position.
When the permissible limit is exceeded by ±3%, error code
E03
will appear on the display.
7.11 Signal Output
The ejector has a signal output. The signal output can be configured using the corresponding menu item.
The signal output OUT can be switched between [ no ] (normally open) and [ nc ] (normally closed) contact. You can switch it in the configuration menu using the [
0-2
] menu item or set it via IO-Link. The function of the limit value H2/h2 (“Part Present” check) is assigned to the signal output OUT.
The signal output is switched on or off when the system vacuum is higher or lower than the relevant threshold value.
The output type parameter can be used to switch between PNP and NPN. The signal inputs are also configured with this function. This setting can be switched using the [ tYP
] menu item in the configuration menu or via IO-Link.
7.12 Signal Type
The signal type, or the switching behavior (PNP or NPN) of the electrical signal inputs and the signal output, can be set on the device and therefore does not depend on the version. You can switch this setting using the [ tYP
] menu item in the configuration menu or via IO-Link. The ejector is factory set to PNP.

7.16 Switch-off Delay
You can use this function to set a switch-off delay for the H2 “Part Present” check signal. This can be used to mask short-term fluctuations in the vacuum level of the vacuum system. The duration of the switch-off delay can be set with the parameter [ dlY ] in the configuration menu or via IO-Link. The value can be set to 10, 50 or 200 ms. To deactivate this function, enter the value [
000
] (= off).
The switch-off delay affects the OUT
2
discrete output, the process data bit in IO-Link and the H2 status display
If the OUT
2
output is configured as a normally open contact [no], there will be an electrical switch-off delay. On the other hand, if it is configured as a normally closed contact [nc], there will be an equivalent switch-on delay.
7.17 ECO Mode
The ejector offers the option to switch off the display to save energy. If ECO mode is activated, the display is switched off and the system power consumption is reduced after 2 minutes if no buttons are pressed.
ECO mode can be activated and deactivated using the [ Eco ] parameter in the configuration menu or via
IO-Link.
A red dot in the lower right corner of the display indicates that the display has been switched off.
The display is reactivated by pressing any button or by an error message.
If you activate ECO mode using IO-Link, the display will immediately enter energy-saving mode.
7.18 Write Protection
A PIN can be used to prevent the parameters from being changed via the user menu.
The current settings are still displayed. The PIN is set to
000
on delivery. meaning access to the parameters is not locked. A valid PIN between 001 and 999 must be entered to activate write protection. If write protection is activated with a customer-specific PIN, the desired parameters can be changed within one minute after the correct code is entered. If no changes are made within one minute, write protection is automatically reactivated. The PIN 000 must be set again to permanently deactivate the lock.
Full access to the ejector is still possible via IO-Link even if a PIN is enabled. The current PIN can also be read out and changed/deleted (PIN =
000
) via IO-Link.
You enter the PIN using the
PIN
parameter in the configuration menu or via IO-Link.
In IO-Link mode, the “Device access locks” default parameter is available to prevent changes to parameter values using the user menu or IO-Link. You can also prevent the use of the Data storage mechanism described in IO-Link Standard V1.1.

7.20 Counters
The ejector has two internal counters, [ cc1
] and [ cc2
], which cannot be erased:
Counter 1 increases with each valid pulse at the “suction” signal input, meaning that it counts all the suction cycles during the ejector’s service life. Counter 2 increases each time the “suction” valve is switched on. As a result, the average switching frequency of the air saving function can be determined using the difference between counters 1 and 2.

General Description of Functions
7.26.1 Condition Monitoring (CM)
Monitoring the valve switching frequency:
When the air saving function is activated and there is a high leakage level in the gripping system, the ejector switches between the suction and suction-off states very frequently. The number of valve switching procedures thus increases rapidly within a short time. To protect the ejector and increase its service life, the ejector switches the air saving function off automatically at a switching frequency of more than 6 times every 3 seconds and activates continuous suction; the ejector then remains in the suction state. In
IO-Link mode, the appropriate condition monitoring warning is also set. In addition, the system status light switches to yellow.
The basic monitoring for the valve protection function is also active in SIO mode.

Monitoring the Control:
If the vacuum limit value H1 is never reached during the suction cycle, the “H1 not reached” condition monitoring warning is triggered and the system status light switches to yellow.
This warning is available at the end of the current suction phase and remains active until the next suction cycle.
Measuring and monitoring the evacuation times: t0 is the time from the beginning of a suction cycle to when the vacuum limit value H2 is reached (in ms).
t1 is the time from when the vacuum limit value H2 is reached to when the vacuum limit value H1 is reached (in ms).

If the measured evacuation time t1 (from H2 to H1) exceeds the specified value [t-1], the “Evacuation time longer than t-1” condition monitoring warning is triggered and the system status light switches to yellow.
The specified value for the max. permitted evacuation time can be set under the [ t-1
] menu item in the configuration menu or via IO-Link. Setting the value to “0” deactivates monitoring. The maximum permitted evacuation time setting is 9.99 seconds.
Leakage monitoring:
In control mode ([ ctr
] = [ on5
]), the loss of vacuum within a certain period is monitored (mbar/s). There are two possible statuses.
Leakage L < permitted value -L-
If the leakage is lower than the set value, the vacuum continues to fall until it reaches the vacuum limit value H1-h1, and the ejector begins with suction again (normal control mode).
The condition monitoring warning is not activated and there is no effect on the system status light.
Leakage L > permitted value -L-
If the leakage is higher than the value, the ejector readjusts immediately.
If the permitted leakage is exceeded twice, the ejector switches to continuous suction.

General Description of Functions
Dynamic pressure monitoring:
If possible, a dynamic pressure measurement is taken at the start of every suction cycle. The result of this measurement is compared to the vacuum limit values set for H1 and H2.
If the dynamic pressure is greater than (H2 - h2) but less than H1, the corresponding condition monitoring warning will be set and the system status light will switch to yellow.
Leakage level evaluation:
This function determines the average leakage during the last suction cycle, divides it into subareas and makes it available as a parameter via IO-Link.
Autoset
The CM Autoset IO-Link function in the process output data allows the condition monitoring parameters for maximum permitted leakage [
-L-
] and the evacuation time [ t-1
] to be set automatically. The actual values from the last suction cycle are combined with additional tolerance and stored.
7.26.2 Energy Monitoring (EM)
To optimize the energy efficiency of the vacuum gripping systems, the ejector provides functions for measuring and displaying energy consumption.
Percentage-based air consumption measurement:
The ejector calculates the air consumption from the last suction cycle as a percentage. This value corresponds to the ratio for the full duration of the suction cycle and the active suction and blow off times.
Absolute air consumption volume:
An externally recorded pressure value can be supplied using the IO-Link process data. If this value is available, not only a percentage-based air consumption measurement, but also an absolute air consumption measurement can be performed. The actual air consumption of a suction cycle is calculated taking the system pressure and nozzle size into account.
An absolute air consumption measurement can be made only using a pressure value supplied externally via IO-Link.
The measured value for the absolute air consumption (air consumption per cycle) is reset at the start of suction and then continuously updated during the cycle. It can continue to change until after the end of blow-off.
Energy consumption measurement:
The ejector determines the electrical energy consumed during a suction cycle, including the energy it consumes itself and the energy consumed by the valve coils.
To determine the values for the air consumption as a percentage and the electrical energy consumption, the neutral phase of the suction cycle must also be taken into account. Therefore, the measured values can only ever be updated when the next suction cycle begins. Throughout the cycle, the measured values displayed then represent the results from the previous cycle.
7.26.3 Predictive Maintenance (PM)
For early detection of wear and other impairments to the vacuum gripper system, the ejector features functions for detecting trends in the quality and performance of the system. The leakage and dynamic pressure are measured for this purpose.
Measurement of leakage:
The leakage (represented as the vacuum drop per time unit in mbar/s) after the control function interrupts suction because the vacuum limit value H1 has been reached is measured.
36 / 72 EN-US · 30.30.01.01484 · 00 · 01/21
General Description of Functions
The measured value for the leakage rate and the related quality assessment in percent are reset at the start of every suction cycle and constantly updated during the cycle as moving averages. The values therefore remain stable until after the suction cycle is complete.
Measurement of dynamic pressure:
This measures the system vacuum achieved during unobstructed suction. The duration of the measurement is approx. 1 second. Therefore, to evaluate a valid dynamic pressure, uninterrupted suction is required for at least 1 second after starting the suction, i.e. the suction point must not be covered by a part.
Measured values below 5 mbar or above the vacuum limit value H1 are not regarded as valid dynamic pressure measurements and are rejected. The result of the last valid measurement is retained. Measured values that are higher than the vacuum limit value (H2-h2) and simultaneously lower than vacuum limit value H1 result in a condition monitoring event.
The dynamic pressure (vacuum during unobstructed suction) and the related performance assessment in percent are initially unknown when the ejector is switched on. As soon as a dynamic pressure measurement can be performed, they are updated and retain their values until the next dynamic pressure measurement.
Quality assessment:
To evaluate the overall gripping system, the ejector calculates a quality rating based on the measured system leakage. The greater the leakage in the system, the worse the quality rating of the gripping system.
Conversely, low leakage results in a high quality rating.
Performance calculation:
Similar to the quality assessment, the performance calculation is used to evaluate the system status. The performance of the gripping system can be assessed based on the determined dynamic pressure. Optimally configured gripping systems lead to low dynamic pressure and thus to high performance. Conversely, poorly configured systems result in low performance. Dynamic pressure events that exceed the vacuum limit value (H2-h2) always result in a performance rating of 0%. A dynamic pressure value of
0 mbar (indicator that a valid measurement was not obtained) also results in a performance rating of 0%.
7.26.4 Diagnostic Buffer
The condition monitoring warnings described above and the general error messages from the device are saved in an integrated diagnostic buffer. The content of this memory is made up of the last 38 events, starting with the most recent, and can be read out via an IO-Link parameter. For each event, the current reading of the suction cycle counter cc1 is also saved to allow subsequent temporal assignment of the events to other processes in the system. See the associated IO-Link Data Dictionary for the actual data display of the diagnostic buffer. The recording of these events is also active in SIO mode and the contents of the memory is retained after a power failure.
The memory is deleted manually using the IO-Link system command “Clear diagnostic buffer” or also by restoring the factory settings on the device.
7.26.5 EPC Data Buffer
The ejector provides a ten-stage data buffer to enable long-term monitoring and trend analysis of the most important key figures in a handling process. The current measured values for the evacuation time t1, leakage rate and dynamic pressure (vacuum during unobstructed intake), which are determined during the suction cycle, can be saved in this buffer. The values are saved automatically, always together with the execution of the autoset function in the condition monitoring area described above. For each data record, the current reading of the suction cycle counter cc1 is also saved to allow subsequent temporal assignment to other processes in the system. The contents of the EPC data buffer can be read out via an IO-Link parameter. See the associated IO-Link Data Dictionary for the actual data display of this buffer. The contents of the memory remains intact after a power failure.

7.26.6 EPC Values in the Process Data
To quickly and easily capture the most important results from the condition monitoring [CM], energy monitoring and predictive maintenance functions, these are also made available via the process input data of the device. The top 3 bytes of the process output data are also configured as a multifunctional data range, consisting of an 8 bit value (“EPC Value 1”) and a 16 bit value (“EPC Value 2”).
The contents of this data that are currently supplied can be switched via the Process Data Out using the 2
“EPC-Select” bits.

The switch is made depending on the structure of the automation system with some time delay. However, to ensure that the different pairs of values can be read efficiently through a controller program, the bit
EPC-Select-Acknowledge is provided in the process input data. The bit always accepts the values shown in the table.
To read out all EPC values, the procedure illustrated in the following diagram is recommended:
1. Start with EPC-Select = 00.
2. Create the selection for the next value pair you require (e.g. EPC-Select = 01)
3. Wait until the EPC-Select-Acknowledge bit changes from 0 to 1.
ð The transmitted values correspond to the selection you have created, and can be adopted by the control system.
4. Switch back to EPC-Select = 00.
5. Wait until the EPC-Select-Acknowledge bit from the device is reset to 0.
6. Proceed in the same way for the next value pair (e.g. EPC-Select = 10).
The following diagram illustrates the sequence for the EPC system query.

4 If you notice that the performance of the ejectors has declined, replace the screens.
13.6 Replacement of the Device with a Parameterization Server
The IO-Link protocol provides 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.
ü The device is operated on a master with IO-Link version 1.1 or higher.
ü The Data storage feature in the configuration of the IO-Link port is activated.
4 Ensure that the new device is restored to the factory settings before it is connected to the IO-Link master. If necessary, reset the device to the factory settings.
ð The device parameters are automatically mirrored in the master when the device is configured using an IO-Link configuration tool.
ð Changes to the parameters made in the user menu on the device or via NFC are mirrored in the master.
Changes to the parameters made by a PLC program using a function module are not automatically mirrored in the master.
4 Manually mirroring data: After changing all the required parameters, execute ISDU write access to the “System Command” parameter [0x0002] using the command “Force upload of parameter data into the master” (numerical value 0x05) (see Data Dictionary).
Use the Parameterization server function of the IO-Link master to ensure that no data is lost when switching the device.
