- a typical measuring device initially consists of a sensor element, also referred to as a measuring transducer, which serves to detect and convert a physical measured quantity of a process value into a measuring signal. Furthermore, an evaluation unit is provided which is frequently designed as a microcontroller and in which the measurement signals generated by the sensor element are processed, i. reinforced, and mostly already processed. On the output side, the evaluation unit is connected to an interface via which the conditioned measurement signals are sent to the already mentioned control unit in the form of binary switching signals or
- Analog signals can be transmitted.
- the IO-Link standard is a special communication system of the
- IO-Link Industrial automation, which is used to connect intelligent sensors and actuators, which are also referred to as field devices, to the control unit, provided that the control unit is IO-Link-capable, i. is designed for such communication.
- the IO-Link standard is standardized in the standard IEC 61131 -9 under the designation "Single-drop digital communication interface for small sensors and actuators" (SDCI).
- SDCI Single-drop digital communication interface for small sensors and actuators
- Connection data as well as a digital communication protocol through which the Sensors and actuators interact with the IO-Link-capable control unit.
- the object of the invention is to develop the above-mentioned communication system of automation and process technology such that it allows the user to easily access the data of a located in the communication system IO-link-enabled sensor, if the control unit itself for this purpose not suitable.
- the object is achieved with a communication system with the features of claim 1 and a Y-turnout unit for such
- the communication line via which the controller is connected to one another at its analog or switching signal input and a sensor, is subdivided into two sub-lines and a Y-diverter unit is used at the connection point.
- the term "Y-turnout unit" results from the fact that the sensor side, a first terminal and the control side, a second and a third terminal are provided.
- the controller is connected to the second connection and a further data receiver is connected to the third connection.
- the Y-switch unit provides the digital data according to the IO-Link standard of the sensor at the third connection to the other data receiver.
- the Y-turnout unit comprises an evaluation and
- Processing unit which comprises a scanning unit, a microcontroller and an amplifier unit according to an advantageous development.
- Processing unit accesses the sensor's digital IO-Link data, analyzes the protocol, extracts the original binary switching signal from it and finally makes it available to the controller at the second connection.
- the further data receiver can now query the digital data of the sensor without affecting the interface between the sensor and the controller.
- the signals from the first port to the third port i. from the sensor to the other data receiver in which Y-turn unit is forwarded directly and unchanged, so to speak, while the connection between the first and second connection, i. from the sensor to the controller, characterized in that the signals are guided here in the Y-points unit on the evaluation and processing unit and there the binary switching signal is taken from the digital IO-link signal.
- non-intelligent control unit can continue to receive the sensor's binary switching signals, it is still able to access communication data of an IO-Link-capable sensor located in the communication system.
- Data receiver has an interface for connection to a corporate network and / or a portable data processing device (tablet, smartphone, laptop, etc.).
- the connection can be wired, for example via LAN or USB, but also wirelessly, eg via Bluetooth or WLAN.
- the sensor data are then - independently of one another - available both in the control network and in a conventional company network or on mobile data processing devices, despite the often required strict separation of these two networks.
- the invention will be explained in more detail by means of embodiments with reference to the drawings.
- Figure 1 shows an inventive communication system of automation and process technology
- FIG. 2 is a block diagram of a Y-turnout unit according to the invention
- FIG. 3 is a block diagram of another embodiment of the invention.
- FIG. 2 Y-turnout unit according to the invention shown in FIG. 2.
- FIG. 1 shows schematically an inventive communication system 1 of the automation and process technology is shown.
- the focus is a Y-turnout unit 10 with three terminals 10a, 10b, 10c, wherein a first terminal 10a is arranged on the sensor side and the other two terminals 10b, 10c are arranged on the control side.
- a sensor 3 is connected. This can be any type of sensor or measuring device, the or in the
- Temperature, flow or level sensor is an intelligent sensor that is actually suitable for exchanging digital data with a controller, eg a PLC, according to the IO-Link standard.
- this primarily means data which characterizes the sensor itself, such as e.g. a serial number, an identifier, diagnostic or parameter data.
- the control unit 2 has only one analog and / or switching signal input and thus is not suitable for IO-Link communication, this additional data would remain unused as it is not retrieved or processed by the non-intelligent controller 2 can.
- the controller 2 is on the second Terminal 10b and the other data receiver 4 at the third terminal 10c connected to the Y-switch unit 10.
- the data receiver 4 is in particular an IO-Link master.
- the data receiver 4 optionally has a dashed line because of this
- Interface 5 for connection to a company network 5a and / or a portable data processing device (tablet, smartphone, laptop, etc.).
- the connection can be wired, for example via LAN, USB, or wireless, for example. Via Bluetooth or Wi-Fi, done. This makes it possible to read the sensor data from the data receiver 4 and process it further.
- Sensor data are then - independently of each other - both in the control network 2 and in a conventional company network 5a or on mobile
- the Y-turnout unit 10 is shown in detail in the form of a block diagram.
- the three terminals 10a, 10b, 10c each comprise four pins, with "+” and in each case the positive or negative operating voltage is meant. In order not to overload the figure was dispensed with an explicit wiring of these pins and the connection options therefore only hinted.
- there is one pin each for picking up the acquired measured values here by way of example in the form of an analog signal, and a pin via which digital signals are transmitted according to the IO-Link standard or binary switching signals (SIO: Serial Input Output).
- the analog signal is looped through and is shown here only as an option; the main focus is on the fourth pin, over which the digital or binary signal is transmitted.
- the line for the IO-link signal is divided and fed directly to the third terminal 10 c, in which the
- Data receiver 4 is connected, and on the other hand, the second terminal 10b supplied to which the controller 2 is connected, wherein the IO-link signal before a further evaluation and processing unit 11 is supplied, the one Protocol scan 11 a, a protocol analyzer 11 b and an amplifier unit 11 c includes.
- the protocol scan 11 a is preferably implemented as a hardware circuit and scans the digital IO-link signal, which is applied to the sensor terminal 10 a and supplies it to the protocol analyzer 11 b.
- the protocol analyzer 11 b is as
- Microcontroller with integrated IO-Link stack implemented, which is used to interpret the protocol and from this the switching information contained
- the amplifier unit 11 c is preferably again as
- Executed hardware circuit serves to reprocess the switching signals in the form understandable for the controller 2 form again.
- the conditioned switching signal is then provided to the controller 2 at the second terminal 10b.
- connection between the first terminal 10a and the third terminal 10c to which the data receiver 4 is connected is indicated by the two oppositely directed arrows as a bidirectional communication line. That The IO-Link master as the further data receiver 4, it is also possible to access the sensor 3 and there, for example, make a parameterization. Only one signal transmission from the sensor 3 to the controller 2 is possible on the connections between the first connection 10a and the second connection 10b.
- FIG. 3 shows the Y-turnout unit 10 in more detail and with some advantageous developments.
- the protocol scan 11 a still includes a master stack 11 d and a device stack 11 e, which are basically already included in Fig. 2, but there are not mentioned for purposes of illustration.
- a master is given to the sensor 3 at the first terminal 10 a, while the device stack 11 e sends to the data receiver 4 at the third terminal 10 c a device, i. a sensor is specified.
- a first difference from FIG. 2 is that the IO-Link signals between the first terminal 10a and the third terminal 10c are now routed via the evaluation and processing unit 11, i. first via the master stack 11 d and then via the device stack 11 e. Through this execution, the
