Overview
IOLB-7014 Module Overview
The IOLB-7014 provides four configurable differential analog inputs. The IOLB-7014 is intended to be connected directly to an IO-Link Master without an additional coupler box.
The small IOLB-7014 form factor of only 126 x 30 x 26.5 mm (h x w x d), which means that they are suitable for use where space is at a premium. The small mass of the IOLB-7014 module facilitates applications with mobile I/O interface (for example, a robot arm).
The robust design of the IOLB-7014 module enables them to be used directly at the machine. Control cabinets and terminal boxes are now no longer required. The module is fully sealed and therefore ideally prepared for wet, dirty or dusty conditions (IP67).
Pre-assembled cables significantly simplify IO-Link and signal wiring. Very few wiring errors are made, so that commissioning is optimized. In addition to pre-assembled IO-Link, power and sensor cables, field- configurable connectors and cables are available for maximum flexibility. Sensors and actuators are connected through M12 connectors.
Configurable Analog Differential Inputs
The IOLB-7014has four analog inputs that can be parameterized individually so that they process either signals in the range of -10 V to
+10 V or in the range of 0/4 mA through 20 mA. The voltage or the input current is digitized with a resolution of 16 bits and transported galvanically separated to the higher-level automation device.
The four input channels are differential inputs and have a common, internal ground potential. The input filters and associated conversion times can be set in a wide range. The scaling of the inputs can be changed if necessary; Automatic limit monitoring is also available.
Parameterization is done through IO-Link. The parameters are stored on the module.

IO-Link System
IO-Link System
An IO-Link system consists of an IO-Link Master, one or more IO-Link devices and sensors or actuators. The
IO-Link Master provides the interface to the higher-level controller and controls the communication with the connected IO-Link devices. The Comtrol IO-Link Master series has four or eight IO-Link ports at which each one IO-Link device can be connected. therefore IO-Link is not fieldbus, but rather is a peer-to-peer connection
(see figure below).
The connected IO-Link devices have individual parameter information detected during automatic scanning with the Comtrol IO-Link Master. Refer to
Configuring the IOLB-7014 on Page 21 for more information.

Structure of IO-Link Communication
Structure of IO-Link Communication
The structure of the IO-Link communication is shown in the following figure. In particular, this represents the sequence in the automatic scanning of the IO-Link ports.
• If the stored consistent with the read parameters, so changes the IO-Link device in the PREOP status.
• If it is an IO-Link device specification V1.1, the parameter server is now running. If it is in an IO-Link device according to V1.0, this step is omitted and connected directly in the operating room.
• Finally, the cycle time is written and switched the device in the operating room. After that is the master in the cyclical data exchange with the slave.

The filter performs a notch filter function and determines the conversion time of the module.
The higher the filter frequency, the faster the conversion time. A 50 Hz and a 60 Hz filter are available.
Notch filter means that the filter has zeros
(notches) in the frequency response at the filter frequency and multiples thereof, that is, it attenuates the amplitude at these frequencies.
The FIR filter functions as a non-recursive filter.
Note: Typical attenuation curve of notch filter at 50 Hz

Full Scale Value
An I/O device with an analog input measures over a nominal measuring range that is limited by an upper and a lower limit (initial value and end value); these can usually be taken from the IOLB-7014 designation. The range between the two limits is called the measuring span and corresponds to the equation (end value - initial value). Analogous to pointing devices this is the measuring scale (see IEC 61131) or also the dynamic range.
For the above examples this means:
• Measuring range 0 to 10V: asymmetric unipolar, full scale value = 10V, measuring span = 10V
• Measuring range 4 to 20mA: asymmetric unipolar, full scale value = 20mA, measuring span = 16mA
• Measuring range -10 to +10V: symmetric bipolar, full scale value = 10V, measuring span = 20V
± Measuring Error [% of the Full Scale Value] (Also: Measurement Error)
The relative measuring error is referenced to the full scale value and is calculated as the quotient of the largest numerical deviation from the true value ( measuring error ) referenced to the full scale value.
Measurement Error = Maximum Deviation/Full Scale Value
The measuring error is generally valid for the entire permitted operating temperature range, also called the usage error limit and contains random and systematic portions of the referred device (that is, all influences such as temperature, inherent noise, aging, etc.).
It is always to be regarded as a positive/negative span with ±, even if it is specified without ± in some cases.
The maximum deviation can also be specified directly.
Example : Measuring range 0 to 10 V and measuring error < ± 0.3 % full scale value - maximum deviation
±30mV in the permissible operating temperature range.

Differential Typification
Differential Typification
This diagram shows the DIFF module.
Note: Dashed lines indicate that the respective connection may not necessarily be present in each DIFF module.
The basic rule:
• Analog measurements always take the form of voltage measurements between two potential points. For voltage measurements a large R is used, in order to ensure a high impedance. For current measurements a small R is used as shunt. If the purpose is resistance measurement, corresponding considerations are applied.
Comtrol generally refers to these two points as input+/signal potential and input-/reference potential.
For measurements between two potential points two potentials have to be supplied.
Regarding the terms single-wire connection or three-wire connection , please note the following for pure analog measurements: three- or four-wire connections can be used for a sensor supply, but are not involved in the actual analog measurement, which always takes place between two potentials/wires.
• The term electrical isolation should be clarified in advance with regard to the channel connection a distinction is made in terms of how the channels:
Within a module relate to each other, or
Of several modules relate to each other.
The property of electrical isolation indicates whether the channels are directly connected to each other.
• The IOLB-7014 features electrical isolation between the field/analog side and the IO-Link side.
• Differential channels are not electrically isolated channel to channel.
• Analog measuring channels are subject to technical limits, both in terms of the recommended operating
Page 7 for information about channel limits.
Differential Explanation
• Differential measurements provide the most flexibility. You can choose both connection points, input+/ signal potential and input-/reference potential, within the framework of the technical specification.
• Since a differential input is configured symmetrically internally (see diagram), there will be a midpotential (X) between the two supplied potentials that is the same as the internal ground/reference ground for this channel. The technical property VCM (common-mode voltage) indicates the degree to which the mean voltage of the channels may differ.
IOLB-7014 User Guide : 2000645 Rev. A Technical Data Overview - 33
Typification of the 2/3/4-Wire Connection of Current Sensors
• The internal reference ground may be accessible as connection point at the IOLB-7014, in order to stabilize a defined GND potential in the IOLB-7014. In this case it is particularly important to pay attention to the quality of this potential (noiselessness, voltage stability). At this GND point a wire may be connected to make sure that V
CM max
is not exceeded in the differential sensor cable. If differential channels are not electrically isolated, usually only one V
CM max
is permitted.
• Differential measurement in combination with correct sensor wiring has the special advantage that any interference affecting the sensor cable (ideally the feed and return line are arranged side by side, so that interference signals have the same effect on both wires) has very little effect on the measurement, since the potential of both lines varies jointly (hence the term common mode). In simple terms: Common-mode interference has the same effect on both wires in terms of amplitude and phasing.
• Nevertheless, the suppression of common-mode interference within a channel or between channels is subject to technical limits, which are specified in the
IOLB-7014 Technical Specifications on Page 7.
Typification of the 2/3/4-Wire Connection of Current Sensors
Current transducers/sensors/field devices (referred to in the following simply as sensor ) with the industrial
0/4-20mA interface typically have internal transformation electronics for the physical measured variable
(temperature, current, etc.) at the current control output. These internal electronics must be supplied with energy (voltage, current). Thus separates the sensors into self-supplied (2-wire) or externally supplied sensors
(3-wire or 4-wire):
• Self-supplied sensors
The sensor draws the energy for its own operation via the sensor/signal wires + and -. So that enough energy is always available for the sensor’s own operation and open-circuit detection is possible, a lower limit of 4mA has been specified for the 4-20mA interface; i.e. the sensor allows a minimum current of 4mA and a maximum current of
20mA to pass.
For a 2-wire connection; see IEC60381-1
Such current transducers generally represent a current sink and thus like to sit between + and – as a variable load . Refer also to the sensor manufacturer’s information.
Therefore, they are to be connected accordingly:
• The sensor draws the energy/operating voltage for its own operation from two supply wires of its own. One or two further sensor wires are used for the signal transmission of the current loop:
• Sensor cable: according to the terminology such sensors are to be connected to single- ended inputs in 3 wires with +/-/Signal lines and if necessary a cable shield
• Sensor cables: In the case of sensors with 4-wire connection according to +-/+Signal/-Signal, you must check whether +Signal may be connected to +Supply or –Signal to –Supply.
Yes: then you can connect accordingly to a Comtrol single-ended input .
The differential input for +Signal and –Signal is to be selected; +Supply and –Supply are to be connected via additional wires.
Note: Expert organizations such as NAMUR demand a usable measuring range <4mA/>20mA for error detection and adjustment, see also NAMUR NE043.

Process Data Calculations
The IOLB-7014 records measured values continuously and places the raw value of its A/D converter into the
ADC raw value objects 2062, 2078, 2094, and 2110. The calculation of the correction with the vendors calibration values takes place after each acquisition of the analog signal. User scaling then follows
