Product Details

Main features

IO-Link Carlo Gavazzi 4-wire DC photoelectric Time Of Flight “TOF” sensors, built to the highest quality standards, are available in two different housing materials.

• Plast ABS. IP67 approved
• Stainless Steel AISI316L for harsh environments. IP69K and ECOLAB approved.

They can operate in standard I/O mode (SIO), which is the default operation mode. When connected to an IO-Link master, they automatically switch to IO- Link mode and can be operated and easily configured remotely. Thanks to their IO-Link interface, these devices are much more intelligent and feature many additional configuration options, such as the settable sensing distance and hysteresis, as well as timer functions of the output. Advanced functionalities such as the Logic function block and the possibility to convert one output into an external input make the sensor highly flexible in solving decentralized sensing tasks.

Identification number

Additional characters can be used for customized versions.

Operating modes

IO-Link photoelectric sensors are provided with two switching outputs (SO) and can operate in two different modes: SIO mode (standard I/O mode) or IO-Link mode (pin 4).

SIO mode
When the sensor operates in SIO mode (default), an IO-Link master is not required. The device works as a standard photoelectric sensor, and it can be operated via a Fieldbus device or a controller (e.g. a PLC) when connected to its PNP, NPN, or push-pull digital inputs (standard I/O port). One of the greatest benefits of these photoelectric sensors is the possibility to configure them via an IO-Link master and then, once disconnected, they will keep the last parameter and configuration settings. In this way it is possible, for example, to configure the outputs of the sensor individually as a PNP, NPN, or push-pull, or to add timer functions such as T-on and T-off delays or logic functions and thereby satisfy several application requirements with the same sensor.

IO-Link mode

• IO-Link is a standardized IO technology that is recognized worldwide as an international standard (IEC 61131-9). It is today considered to be the “USB interface” for sensors and actuators in the industrial automation environment.
• When the sensor is connected to one IO-Link port, the IO-Link master sends a wakeup request (wake-up pulse) to the sensor, which automatically switches to IO-Link mode: point-to-point bidirectional communication then starts automatically between the master and the sensor.
• IO-Link communication requires only standard 3-wire unshielded cable with a maximum length of 20 m.

IO-Link communication takes place with a 24 V pulse modulation, standard UART protocol via the switching and communication cable (combined switching status and data channel C/Q) PIN 4 or black wire.

For instance, an M8 4-pin male connector has:

• Positive power supply: pin 1, brown
• Negative power supply: pin 3, blue
• Digital output 1: pin 4, black
• Digital output 2: pin 2, white

The transmission rate of LD30xxBI10…IO sensors is 38.4 kBaud (COM2).
Once connected to the IO-Link port, the master has remote access to all the parameters of the sensor and advanced functionalities, allowing the settings and configuration to be changed during operation, and enabling diagnostic functions, such as temperature warnings, temperature alarms, and process data.

Thanks to IO-Link it is possible to see the manufacturer information and part number (Service Data) of the device connected, starting from V1.1. Thanks to the data storage feature it is possible to replace the device and automatically have all the information stored in the old device transferred into the replacement unit.

• Access to internal parameters allows the user to see how the sensor is performing, for example by reading the internal temperature.
• Event Data allows the user to get diagnostic information such as an error, an alarm, a warning, or a communication problem.

There are two different communication types between the sensor and the master and they are independent of each other:

• Cyclical for process data and value status – this data is exchanged cyclically.
• Acyclical for parameter configuration, identification data, diagnostic information, and events (e.g. error messages or warnings) – this data can be exchanged on request.

Process data

• By default the process data shows the following parameters as active: 16-bit Analogue value, Switching Output1 (SO1), and Switching Output 2 (SO2).
• The following parameters are set as Inactive: SSC1, SSC2, TA, SC.
• However, by changing the Process Data Configuration parameter, the user can decide to also enable the status of the inactive parameters. This way several states can be observed in the sensor at the same time.
• Process data can be configured. See 2.6.3. Process data configuration.

• 4 Bytes
• Analogue value 16 … 31 (16 BIT)

Output Parameters

• The sensor measures four different physical values. These values can be independently adjusted and used as a source for the Switching Output 1 or 2; in addition to those, an external input can be selected for SO2. After selecting one of these sources, it is possible to configure the output of the sensor with an IO-Link master, following the six steps shown in the Switching Output setup below.
• Once the sensor has been disconnected from the master, it will switch to the SIO mode and keep the last configuration setting.

Sensor front
The TOF sensor measures the distance to an object by emissing small pulses of IR-laser light and then measures the time for the light, reflected by an object, to return to the sensor.

SSC (Switching Signal Channel)
For the presence (or absence) detection of an object in front of the face of the sensor, the following settings are available: SSC1 or SSC2. Setpoints can be set from 10 … 2000 [mm]*.

It is not recommended to use settings higher than a maximum of 1000 mm however under optimal conditions (object surface, ambient light environment EMC noise, etc.) the distance can be set at a higher value.

Switchpoint mode:
Each SSC channel can be set to operate in 3 modes or be disabled. The Switchpoint mode setting can be used to create more advanced output behavior. The following switching modes can be selected for the switching behavior of SSC1 and SSC2

Disabled
SSC1 or SSC2 can be disabled individually.

Single point mode
The switching information changes, when the measurement value passes the threshold defined in setpoint SP1, with rising or falling measurement values, taking into consideration the hysteresis.

Two point mode
The switching information changes when the measurement value passes the threshold defined in setpoint SP1. This change occurs only with rising measurement values. The switching information also changes when the measurement value passes the threshold defined in setpoint SP2. This change occurs only with falling measurement values. Hysteresis is not considered in this case.

Window mode
The switching information changes, when the measurement value passes the thresholds defined in setpoint SP1 and setpoint SP2, with rising or falling measurement values, taking into consideration the hysteresis.

Hysteresis Settings

• Range 5 … 2000. Hysteresis unit is mm.
• Hysteresis can manually be set for Single Point Mode or Window Mode for both SSC1 and SSC2 independently.
• However, SSC1 has an extra feature, Automatic hysteresis. Automatic hysteresis supports Single Point Mode and Windows Mode.
• Use parameter “SSC1 Hyst Mode” to choose between Manuel/Automatic hysteresis.

Note: When trimmer is selected, hysteresis is always Automatic.

Automatic hysteresis:

• Automatic hysteresis will guarantee stable operation for most applications.
• Hysteresis is calculated concerning SP1/SP2. Actual values can be read via the parameter “SSC1 Auto hysteresis value”.

Manuel hysteresis:
For applications that require a hysteresis other than the automatic, the hysteresis can be configured manually. This feature makes the sensor more versatile.

Note:
Special attention to the application must be considered when choosing a hysteresis lower than the automatic hysteresis.

Temperature alarm (TA)

• The sensor constantly monitors the internal temperature. Using the temperature alarm setting it is possible to get an alarm from the sensor if temperature thresholds are exceeded. See §2.6.5.
• The temperature alarm has two separate values, one for setting maximum temperature and one for setting minimum temperature.
• It is possible to read the temperature of the sensor via the acyclic IO-Link parameter data.

NOTE!

• The temperature measured by the sensor will always be higher than the ambient temperature, due to internal heating.
• The difference between ambient temperature and internal temperature is influenced by how the sensor is installed in the application.

External input
The Output 2 (SO2) can be configured as an external input allowing external signals to be fed into the sensor, this can be from a second sensor a PLC, or directly from machine output.

Input selector
This function block allows the user to select any of the signals from the “sensor front” to Channel A or B. Channels A and B: can select from SSC1, SSC2, Temperature alarm, and External input.

Logic function block

• In the logic function block a logic function can be added directly to the selected signals from the input selector without using a PLC – making decentralized decisions possible.
• The logic functions available are: AND, OR, XOR, and SR-FF.

AND function

OR function

XOR function

“Gated SR-FF” function
The function is designed to: e.g. function as a filling or emptying function using only two interconnected sensors

X – no changes to the output.

Timer (Can be set individually for Out1 and Out2)
The Timer allows the user to introduce different timer functions by editing the 3 timer parameters:

• Timer mode
• Timer scale
• Timer value

Timer mode
This selects which type of timer function is introduced on the Switching Output. Any one of the following is possible:

Disabled
This option disables the timer function no matter how the timer scale and timer delay are set up.

Turn On Delay (T-on)
The activation of the switching output is generated after the actual sensor actuation as shown in the figure below.

Turn Off delay (T-off)
The deactivation of the switching output is delayed until after the time of removal of the margin at the front of the sensor, as like shown in the figure below.

Turn ON and Turn Off delay (T-on and T-off)
When selected, both the T-on and the Toff delays are applied to the generation of the switching output.

One shot leading edge
Each time a target is detected in front of the sensor the switching output generates a pulse of constant length on the leading edge of the detection. This function is not retriggerable. See the figure below.

One shot trailing edge
Similar in function to the one-shot leading edge mode, but in this mode the switching output is changed on the trailing edge of the activation as shown in the figure below. This function is not retriggerable.

Timer scale
The parameter defines if the delay specified in the Timer delay should be in milliseconds, seconds, or minutes

Timer Value
The parameter defines the actual duration of the delay. The delay can be set to any integer value between 1 and 32 767.

Output Inverter
This function allows the user to invert the operation of the switching output between Normally Open and Normally Closed.

RECOMMENDED FUNCTION
The recommended function is found in the parameters under 64 (0x40) sub-index 8 (0x08) for SO1 and 65 (0x41) sub-index 8 (0x08) for SO2. It has no negative influence on the Logic functions or the timer functions of the sensor as it is added after those functions.

CAUTION!
The Switching logic function found under 61 (0x3D) sub-index 1 (0x01) for SSC1 and 63 (0x3F) sub-index 1 (0x01) for SSC2 is not recommended for use as they will have a negative influence on the logic or timer functions. Using this function will turn an ON delay into an Off delay if it is added for the SSC1 and SSC2. It is only for the SO1 and SO2.

Output stage mode
In this function block the user can select if the switching outputs should operate as:

• SO1: Disabled, NPN, PNP or Push-Pull configuration.
• SO2: Disabled, NPN, PNP, Push-Pull, External input (Active high/Pull-down), External input (Active low/pull up), or External Teach input.

Sensor Specific adjustable parameters
Besides the parameters directly related to output configuration, the sensor also has various internal parameters useful for setup and diagnostics.

Selection of local or remote adjustment
It is possible to select how to set the sensing distance by either selecting the Trimmer or Teach-by-wire using the external input of the sensor or to disable the potentiometer to make the sensor tamperproof.

Trimmer data
A value between 30…1100 mm.

Process data configuration

• When the sensor is operated in IO-Link mode, the user has access to the cyclic Process Data Variable.
• By default the process data shows the following parameters as active: 16-bit Analogue value, Switching Output1 (SO1), and Switching Output 2 (SO2).
• The following parameters are set as Inactive: SSC1, SSC2, DA1, DA2, TA, SC.
• However, by changing the Process Data Configuration parameter, the user can decide to also enable the status of the inactive parameters. This way several states can be observed in the sensor at the same time.

Sensor application setting
The sensor has 3 sensor application presets, which can be selected depending on the application:

• Fast configuration (Filter scaler fixed to 1)
• Precise configuration (Filter scaler fixed to 10 – slow)
• Customized configuration (Filter scaler can be set from 1-255) Precision can be adjusted via pathe rameter “Filter scaler”. See 2.6.9.

Temperature alarm threshold
The temperature at which the temperature alarm will activate can be changed for the maximum and minimum temperature. This means that the sensor will give an alarm if the maximum or minimum temperature is exceeded. The temperatures can be set between -50 °C to +150 °C. The default factory settings are Low threshold -30 °C and high threshold +120 °C.

Event Configuration
Temperature events transmitted over the IO-Link interface are turned off by default in the sensor. If the user wants to get information about critical temperatures detected in the sensor application, this parameter allows the following 4 events to be enabled or disabled:

• Temperature fault event: the sensor detects temperature outside the specified operating range.
• Temperature over-run: the sensor detects temperatures higher than those set in the Temperature Alarm threshold.
• Temperature under-run: the sensor detects temperatures lower than those set in the Temperature Alarm threshold.
• Short-circuit: the sensor detects if the sensor output is short-circuited.

Quality of run QoR
The Quality of the run informs the user about the actual sensor performance.

• “Rating” is a summary of all QoR parameters. If the conditions are good, the object is detected with a good signal, the ambient light low, and the sensor temperature is inside limits, then the Rating is set to 100 (best score).
• If the Rating is < 100, the reason can be read in the other QoR parameters.
• QoR parameters are listed in the table below.

1 = Object not detected

temperature error| 0 = Temperature OK

1 = Temperature outside min/max limits

Quality of Teach QoT
The quality of teaching value lets the user know how well the sensing conditions were during the teaching procedure. The quality of teaching is a snapshot of the quality of run value “Rating”

Filter Scaler
This function can increase the immunity towards unstable targets and electromagnetic disturbances: Its value can be set from 1 to 255, and the default factory setting is 1. The filter functions as a moving average. This means that a filter setting of 1 gives the maximum sensing frequency and a setting of 255 gives the minimum sensing frequency.

LED indication
The LED indication can be configured in 3 different modes: Inactive, Active, or Find my sensor.

1. Inactive: The LEDs are turned off at all times
2. Active: The LEDs follow the indication scheme in 5.1.
3. Find my sensor: The LEDs are flashing alternating with 2Hz with a 50% duty cycle to easily locate the sensor.

• Cutoff distance

  • Range 0…2000 (mm)
  • The measured distance beyond the Cutoff distance will be truncated to the Cutoff distance.
  • Cutoff distance value will also be used when an object cannot be detected.

• Hysteresis mode
  See Hysteresis Settings

• Auto hysteresis value
  See Hysteresis Settings

NOTE!

• The temperature measured by the sensor will always be higher than the ambient temperature, due to internal heating.
• The difference between ambient temperature and internal temperature is influenced by how the sensor is installed in the application. If the sensor is installed in a metal bracket the difference will be lower than if the sensor is mounted in a plastic one.

IODD file and factory setting

IODD file of an IO-Link device
All features, device parameters, and setting values of the sensor are collected in a file called I/O Device Description (IODD file). The IODD file is needed to establish communication between the IO-Link master and the sensor. Every supplier of an IO-Link device has to supply this file and make it available for download on their website.

The IODD file includes:

• process and diagnostic data
• parameters description with the name, the allowed range, the type of data, and the address (index and sub-index)
• communication properties, including the minimum cycle time of the device
• device identity, article number, picture of the device, and Logo of the manufacturer

An IODD file is available on the Carlo Gavazzi Website: TBD

Installation Hints

| | |
---|---|---|---
To avoid interference from inductive voltage/ current peaks, separate the prox. switch power cables from any other power cables, e.g. motor, contactor, or solenoid cables| ****

Relief of cable strain

The cable should not be pulled

| ****

Protection of the sensing face

A proximity switch should not serve as a mechanical stop

| ****

Switch mounted on mobile carrier

Any repetitive flexing of the cable should be avoided
