3.1 Description of the Compact Terminal
Example: SCTMi with 9 ejectors
The Schmalz Compact Terminal SCTMi, or SCTMi for short, is a compact unit of multiple vacuum generators known as ejectors. Thanks to its modular design, up to 16 individual ejectors can be controlled and configured independently. It can be used to handle different parts simultaneously and independently using just one vacuum system.
The Compact Terminal SCTMi has an industrial Ethernet interface. The compressed air supply can be connected centrally for all ejectors. As an alternative, it can also be connected separately for each ejector.
Each ejector has an autonomous energy and process control for monitoring the vacuum circuit.
All settings, parameters and measurement and analysis data are made available centrally via the interface.
Additionally, much of the information and status reports for the Compact Terminal SCTMi can be accessed using wireless communication with NFC (Near Field Communication).
3.2 Description of the Ejector
Ejector SCPSt
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) version, the venturi nozzle is activated.
An integrated sensor records the vacuum generated by the venturi nozzle. The exact vacuum level can be read via the interface.

Product description

Time
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 dense 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.
In Blow-Off mode, the vacuum circuit of the ejector is supplied with compressed air. This ensures that the vacuum drops quickly, depositing the workpiece quickly as well.
The integrated status display shows the current vacuum level with an LED bar and indicates suction or blow-off mode with LEDs.
The ejector also has a button that can be used for manual operation.
3.3 Variants and Type Key
The item designation of the Compact Terminal SCTMi is composed of a type key, which indicates the number of ejectors installed and their precise properties. The digits given in the type key for each ejector correspond to the code of the SCPSt ejector types used and their position in the module.
The SCTMi type key (system configuration), for example SCTMi-EIP-11112222-33334444-P-0-VI00, is composed as follows:

5 Interfaces
5.1 Industrial Ethernet
The industrial Ethernet interface is used to control the entire SCTMi, set all of the parameters and provide a wide variety of measurement and analysis data.
The PROFINET, EtherNet/IP or EtherCAT protocol is supported, depending on the design.
5.2 Process Data
The cyclical process data is used to control the ejectors and receive current information reported from the
Compact Terminal SCTMi. From the perspective of the higher-level PLC, there is a difference between input process data (data from the SCTMi) and output process data (data to the SCTMi):
Device description files are available for integration into a higher-level controller.
The process data width is always the same, regardless of how many ejectors are actually on the
SCTMi.
5.2.1 Input Process Data
The input data provides cyclical reporting of a range of information relating to the SCTMi and the individual ejectors:
• The SCTMi Device Status in the form of a status traffic light
• The switching values H1 and H2 for the connected ejectors
• Error messages from the control unit
• Condition Monitoring events from the control unit and the individual ejectors
The input process data is 23 bytes long.

5.3 Parameter data
More precise information regarding the system status can also be retrieved using the acyclical communication channel.
All of the settings (e.g. control thresholds, switching points, permitted leakage, and so on) for the SCTMi can also be read or modified. You can access additional identifying information for the SCTMi, such as part number and serial number, and save user-specific information such as the installation or storage location.
The precise meanings of the data and functions are further explained in the section “Functions of the
Compact Terminal and the Ejectors.”
For the PROFINET and EtherCAT communication protocols, the following start addresses apply for the parameter data:
SCTMi Variant
PROFINET
EtherCAT
Ethernet/IP
Start Address
0x0000
0x2000
See below
Parameters marked with the addition [ part of processdata ] are also automatically included in the cyclical exchange of process data.
To access the parameter data via Ethernet/IP, an object (also known as a class), an instance and an attribute must be specified in the object-based “Common Industrial Protocol” (CIP).
The 0xA2 object can be used to read—and write, depending on access rights—all parameter data with the following services:
• 0x0E: Get_Attribute_Single
• 0x10: Set_Attribute_Single
The instance corresponds to the offset from the parameter data table.
The following attributes are available:

5.4 Near Field Communication NFC
NFC (Near Field Communication) refers to a standard for wireless data transfer between different devices over short distances. The compact terminal SCTMi functions as a passive NFC tag that can be read or written by a read or write device with NFC active such as a smartphone or tablet. Access to the SCTMi parameters via NFC also works when the supply voltage is not connected.
There are two options for NFC:
• Pure read access is possible via a website displayed in a browser. In this case, no additional app is required. The read device only needs to have NFC active and Internet access.
• Another option is to communicate using the “Schmalz ControlRoom” control and service app. In addition to pure read access, the app allows you actively write the parameters of the SCTMi via NFC.
The Schmalz ControlRoom app is available from the Google Play Store.

Functions of the Compact Terminal and the Ejectors
6 Functions of the Compact Terminal and the Ejectors
6.1 Overview of Functions
The SCTMi primarily consists of the bus module and between 2 and 16 ejectors. The various functions refer to either the bus module or the individual ejector, depending on the function.
The SCTMi bus module has the following general functions, independent of the ejectors:
• Device identification
• System commands
• Access rights
Diagnostics and monitoring functions of the Compact Terminal SCTMi :
The SCTMi provides a variety of diagnostics and monitoring functions:
• Determination of the required system parameters
• Display of the device status through messages and system status traffic lights
• Condition monitoring
Ejector functions
Functions of the ejectors SCPSt:
• Switching points for control and component checks
• Air saving functions
• Blow-off functions
• Setting for the permitted evacuation time t1
• Setting for the permitted leakage
• Permanent and erasable counters for the suction cycles and switching frequency of the valves
• Manual mode 1)
The functions relate to an ejector SCTMi and apply to each individual ejector, regardless of the number of installed ejectors.
1) The Manual Mode function of the ejectors is described in the “Operation” section.
Note about replacing the device: All modifiable parameter data (e.g. switching point settings) is saved in the bus module. When replacing an ejector, the previous data is loaded to the new ejector.
6.2 Device Data
The SCTMi provides a range of identification data that can be used to uniquely identify a specific device.
All of these parameters are ASCII character strings that adapt their length to the relevant content.
The following parameters can be called up:
• Manufacturer's name and website
• Supplier text
• Product name and product text
• Serial number
• Version status of the hardware and firmware
• User ID
• Unique device ID and device properties
• Part number and development status
48 / 74 EN-US · 30.30.01.01598 · 02 · 01/18
Functions of the Compact Terminal and the Ejectors
• Date of manufacture and installation
• Location ID
• System Configuration
• Device ID
• Web link for NFC app and device description file
• Storage ID
6.3 User-Specific Localization
The following parameters are available when saving user-specific information in every individual copy of the SCTMi:
• Identification of the installation location
• Identification of the storage location
• Equipment labeling from the circuit diagram
• Installation date
• Geo-location
The parameters are ASCII character strings with the maximum length given in section 5.3. Parameter data.
They can also be used for other purposes if necessary.
The NFC web link parameter is a special feature. This parameter must include a valid web address beginning with http:// or https:// and is automatically used as a web address for NFC read accesses. As a result, read accesses from smart phones or tablets are rerouted e.g. to an address in the company's own intranet or a local server.
6.4 System Commands (0x0002)
System commands are predefined processes to trigger specific functions. They are controlled by writing parameter 0x0002 with a predefined value.
6.4.1 Reset to Factory Settings
This function is used to reset all settings parameters for the ejector to the factory settings.
Counter statuses, the zero-point adjustment of the sensor and the maximum and minimum values of the measurements are not affected by this function.
6.4.2 Zero-Point Adjustment (Calibration)
Since the sensors installed in the ejectors are subject to variants based on the manufacturing process, it is recommended to calibrate the sensors in the application environment in which the SCTMi will be used.
The vacuum connections of all of the ejectors must be ventilated to the atmospheric pressure before a zero-point adjustment can be made to the sensors.
The “0xA5” system command is used to calibrate the sensors of all of the ejectors.
A zero offset is only possible in the range of ± 3% from the end value of the measurement range.
If the permitted limit of ± 3% is exceeded, this is reported for each ejector via parameter 0x0082.
6.4.3 Reset Counters
This system command is used to delete the two erasable counters in each ejector.
6.4.4 Reset Maximum and Minimum Values for Supply Voltage
The minimum and maximum values of the two supply voltages for the sensor and actuator are deleted.

Functions of the Compact Terminal and the Ejectors
6.5 Block Access with Extended Device Access Locks (0x005A)
In the extended device access locks parameter, there is an option to completely prevent NFC access or limit it to read-only function.
The NFC lock using the extended device access locks parameter has a higher priority than the NFC PIN.
That means that this lock also cannot be bypassed by entering a PIN.
The firmware of the ejectors at the time of delivery is stored on the bus module. When the device is switched on, the existing ejector firmware is updated by the bus module if the ejector firmware corresponds to an older version (local firmware update). This update can be disabled via the extended device access locks parameter.
6.6 PIN code for NFC Write Protection (0x005B)
The writing of changed parameters via NFC can be controlled using a separate PIN code. When delivered, the PIN code is 000 and a lock is therefore not active.
The NFC PIN code can be changed only using this parameter.
When a PIN code is set between 001 and 999, the valid PIN must be entered for every subsequent write process using a mobile NFC device so that the SCTMi accepts the changes.
6.7 Diagnostics and Monitoring Functions of the Compact Terminal
The SCTMi provides a variety of diagnostics and monitoring functions:
• Determination of the required system parameters
• Display of the device status through messages and system status traffic lights
• Condition monitoring
The data collected using this function can be used for energy and process control (EPC) of the SCTMi. Energy and process control (EPC) is divided into three process-oriented 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
6.7.1 Determine SCTMi System Parameters
The system parameters are used for the system monitoring functions and are made available to the user.
The values for the individual ejectors are constantly redetermined for each suction cycle.
Current Operating Voltage (0x0042 and 0x0043)
The U
S
and U
A
operating voltages that are currently applied on the SCTMi are measured.
In addition, the maximum and minimum U
S
and U
A
operating voltages that were measured since the last activation are logged by the SCTMi.
The maximum and minimum values can be reset during operation using the appropriate system command.

Measure Evacuation Time t0 and t1 (0x0094 and 0x0095)
Diagram of function for monitoring evacuation time t0 and t1
Vacuum
[mbar]
Suction ON Time [s]
The evacuation time t0 is defined as the time (in ms) from the start of a suction cycle, which is started by the “Suction ON” command, until switching threshold H2 is reached.
The evacuation time t1 is defined as the time (in ms) from when switching threshold H2 is reached until switching threshold H1 is reached.
Measure Air Consumption (0x009C)
The actual air consumption of a suction cycle is calculated taking the system pressure and nozzle size into account.
The process data can be used to notified the ejector of the actual system pressure. If this is not available, the system operates with the optimum system pressure.
Measure Leakage (0x00A0)
This function measures the leakage (represented as the vacuum drop per time unit in mbar/s) after the air saving function interrupts the suction because switching point H1 was reached.
Measure Dynamic Pressure (0x00A1)
This measures the system vacuum achieved during unobstructed suction (free flow vacuum). 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 switching point H1 are not regarded as valid dynamic pressure measurements and are rejected. The result of the last valid measurement is retained.
Measured values above the switching point (H2 - h2) but simultaneously lower than switching point H1 result in a condition monitoring event.

6.7.2 Device Status
The current status of the SCTMi can be accessed and displayed in a variety of different ways. System states, errors and warning messages are conveyed as follows:
• Using the cyclical process Data In
• Using the Active Error Code parameter
• Using condition monitoring events
• Using the Extended Device Status parameter, which transmits the entire display of the device status with classification of the severity level of errors and warnings.
• The NFC Status parameter is used to display the current status of the NFC data transfer.
Device Status (Process Data) (0x000A)
The overall status of the ejector system is displayed as a traffic light in "Process Data In." All warnings and errors are used to determine the status shown here.
This basic display provides immediate information about the status of the ejector with all its input and output parameters.
Status

Description
SCTMi is working perfectly with optimal operating parameters
SCTMi is working but there are warnings
SCTMi is working but maintenance is required
Error – Safe operation of the SCTMi within the operating limits is no longer ensured (error code is available in the error parameter)
Extended Device Status (0x008A)
The “Extended Device Status” parameter shows the category of the pending event code and the current event code itself.
NFC Status (0x008B)
This parameter is used to determine the current status of the NFC data transfer.
Error Codes (0x0082)
The active error codes for the SCTMi and ejectors are displayed using individual bits.
6.7.3 Condition Monitoring [CM] (0x0092)
Any condition monitoring events that occur during the suction cycle cause the system status light to immediately switch from green to yellow. The specific event that caused this switch can be seen in the “Condition Monitoring” parameter.
Condition monitoring for the ejectors describes events that can only occur once per suction cycle. They are reset at the start of every suction cycle and remain stable until after suctioning has finished. Bit number 4, which describes excessive dynamic pressure, is initially deleted when the device is switched on and is only updated when a dynamic pressure value is detected again.
The condition monitoring events for the bus module are constantly updated independently of the suction cycle and reflect the current values for the supply voltages and system pressures.
The measurement values for condition monitoring – the evacuation times t0 and t1 as well as the leakage range – are reset at the start of every suction cycle and updated at the point in time when they can be measured.
Monitor 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.
52 / 74 EN-US · 30.30.01.01598 · 02 · 01/18
Functions of the Compact Terminal and the Ejectors
To protect the ejector and increase its service life, the ejector automatically deactivates the air saving function and switches to continuous suction if the switching frequency > 6/3 s (more than 6 switching operations within 3 seconds). In this case the ejector remains in the Suction state.
It also issues and warning and sets the corresponding condition monitoring bit.

Monitor Evacuation Time
If the measured evacuation time t1 (from H2 to H1) exceeds the specified value, the “Evacuation time longer than t-1” condition monitoring warning is triggered and the system status light switches to yellow.
Monitor Leakage
In control mode, the loss of vacuum within a certain period is monitored (mbar/s). There are two possible statuses.

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. The condition monitoring warning is activated and the system status light switches to yellow.
Monitor Control Threshold
If the switching point H1 is never reached during the suction cycle, the “H1 not reached” condition monitoring warning is be 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.
Monitor Dynamic Pressure
If possible, a dynamic pressure measurement is taken at the start of every suction cycle (vacuum during unobstructed suction). The result of this measurement is compared to the 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 is triggered and the status light switches to yellow.
Monitor Supply Voltages
The SCTMi 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 SCTMi measures the level of the U
S
and U
A
supply voltages. The measured value can be read from the parameter data.
If the voltages are outside the valid range, the following status messages change:
• Device status
• Condition monitoring parameter
EN-US · 30.30.01.01598 · 02 · 01/18 55 / 74
Functions of the Compact Terminal and the Ejectors
• Bus module LED flashes
If there are undervoltages, the valves are no longer activated and the ejectors return to their basic setting:
• NO ejectors switch to Suction mode.
• NC ejectors switch to Pneumatically OFF mode.
If the ejector is in manual mode, it exits manual mode.
A condition monitoring event is also generated If there is an overvoltage.
Evaluate System Pressure
The internal analysis functions on the ejectors sometimes require the system pressure with which the ejectors are operated. To make the results more precise, the actual pressure level can be communicated to the
SCTMi via the process data. If no level is specified, the optimum operating pressure is assumed for the calculations.
6.8 Ejector SCPSt Functions
Functions of the ejectors SCPSt:
• Switching points for control and component checks
• Air saving functions
• Blow-off functions
• Setting for the permitted evacuation time t1
• Setting for the permitted leakage
• Permanent and erasable counters for the suction cycles and switching frequency of the valves
• Manual mode 1)
The functions relate to an ejector SCTMi and apply to each individual ejector, regardless of the number of installed ejectors.
1) The Manual Mode function of the ejectors is described in the “Operation” section.
6.8.1 Switching Points (0x0064 to 0x0067)
Two separate switching points can be set for the ejector. Each switching point has an activation point and a corresponding hysteresis. The system vacuum is constantly compared to the set values for the switching points during operation.
An LED displays when the switching point for H2 is reached.
The set values for H2 must be lower than the values for H1. The exact configuration conditions can be found in the parameter descriptions.

Once the system vacuum reaches the value for H2, the following responses are triggered:
• The process data bit for H2 is set.
• The H2 LED on the ejector’s display illuminates.
Once the system vacuum reaches the value for H1, the following responses are triggered:
• Depending on whether the air saving function is selected, vacuum generation is interrupted.
• The process data bit for H1 is set.

Functions of the Compact Terminal and the Ejectors
6.8.2 Control Functions (0x006D)
The ejector allows you to save compressed air or prevent a too powerful vacuum from being generated.
Vacuum generation is interrupted once the configured switching point H1 is reached. If leakage causes the vacuum to fall below the hysteresis switching point (H1-h1), vacuum generation resumes.
The following control function operating modes can be chosen:
No Control (Continuous Suction), H1 in Hysteresis Mode
The ejector produces continuous suction with maximum power.
The switch point evaluation for H1 is operated in hysteresis mode.
No Control (Continuous Suction), H1 in Comparator Mode
The ejector produces continuous suction with maximum power.
The switch point evaluation for H1 is operated in comparator mode (window mode).
Control
The ejector switches off vacuum generation when the switching point H1 is reached and switches it back on when the vacuum falls below the hysteresis point (H1-h1). The switch point 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 with Leak Monitoring
This operating mode is the same as the previous mode, with the addition that the leakage rate within the system is measured and compared to the configurable limit value.
If the actual leakage rate exceeds the limit value more than twice in succession, the control function is then deactivated and the ejector switches to continuous suction.
Control without Continuous Suction
This operating mode is the same as the “Control” operating mode but it does not switch to continuous suction when the valve switching frequency is exceeded.
When the control shutoff is deactivated, the suction valve makes frequent adjustments. This can destroy the ejector.
Control with Leakage Monitoring, without Continuous Suction
This operating mode is the same as the “Control function with leakage monitoring” operating mode, but the device does not switch to continuous suction when the permitted leakage is exceeded or when the valve switching frequency is exceeded.
When the control shutoff is deactivated, the suction valve makes frequent adjustments. This can destroy the ejector.
6.8.3 Blow-Off Function (0x006E)
Each ejector offers three blow-off modes for selection:
Externally Controlled Blow-Off
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.
EN-US · 30.30.01.01598 · 02 · 01/18 57 / 74
Functions of the Compact Terminal and the Ejectors
Internally Time-Controlled Blow-Off
After the suction signal is switched off, the ejector switches to blow-off mode automatically for the set time. With this function, the blow-off signal does not have to be additionally controlled.
The blow-off signal is given priority over the suction signal. This applies even when the set blow-off time is very long.
Externally Time-Controlled Blow-Off
The blow-off starts with the blow-off signal and is performed for the set time period. Applying the blowoff signal for a longer time does not lead to a longer blow-off period.
The blow-off signal is given priority over the suction signal. This applies even when the set blow-off time is very long.
6.8.4 Set Permitted Evacuation Time t1 (0x006B)
The permitted evacuation time t1 is specified in milliseconds. The measurement starts when the switching threshold H2 is reached and ends when the switching threshold H1 is fallen below.

The erasable counters can be reset to 0 using the appropriate system commands.
The non-volatile storage of the counter statuses only occurs every 256 steps. When the operating voltage is switched off, up to 255 steps of the counter are lost.
6.8.7 Manual Mode
In manual mode, the “Suction” and “Blow-off” ejector functions can be controlled independently of the higher-level controller using the button on the operating panel.
Because the valve protection function is deactivated in manual mode, this function can be used to locate and rectify leaks in the vacuum circuit.
Further information about the ejectors’ manual mode is found in the “Operation” section.

To ensure problem-free operation and a long service life of the compact terminal’s ejectors, only use adequately maintained compressed air and consider the following requirements:
• Air or neutral gas filtered to 5 µm, oiled or not oiled.
• Dirt particles or foreign bodies in the ejector connections, hoses or pipelines can lead to partial or complete ejector malfunction.
1. Shorten the hoses and pipelines as much as possible.
2. Keep hose lines free of bends and crimps.
3. Only use a hose or pipe with the recommended internal diameter to connect the compact terminal, otherwise use the next largest diameter.
4. On the compressed air side, ensure that the internal diameter is adequate for the ejectors to achieve their performance data.
5. On the vacuum side, ensure that the internal diameter is adequate for preventing high flow resistance. Suction capacity and evacuation times will increase, and blow off times will be longer.
6. Plug any unused vacuum connections to reduce noise and prevent foreign bodies from being sucked in.

Operation
9 Operation
9.1 Zero-Point Adjustment (Calibration)
Since the sensors installed in the ejectors are subject to variants based on the manufacturing process, it is recommended to calibrate the sensors in the application environment in which the SCTMi will be used.
The vacuum connections of all of the ejectors must be ventilated to the atmospheric pressure before a zero-point adjustment can be made to the sensors.
The “0xA5” system command is used to calibrate the sensors of all of the ejectors.
A zero offset is only possible in the range of ± 3% from the end value of the measurement range.
If the permitted limit of ± 3% is exceeded, this is reported for each ejector via parameter 0x0082.
