This communication is still mainly per-formed via mechanical buttons, pedals, joy-sticks, lamps and displays – partly with op-erator input functionality. This is another area in which technological advances will create new communication options, such as assistance systems that are controlled by speech.

The HYDAC HMI portfolio includes the G-pro joystick (fig. 03 left). In addition to its remote control transmitter function, it pro-vides the option of controlling hydraulic valves or alternative actuators. It has 6 PWM outputs and 3 switching outputs that can be used for this purpose.

In mobile working machines, it is par-ticularly important for the information on the screen to be easily recognisable, espe-cially given that ambient light conditions can widely vary. HYDAC meets these de-mands with its devices from the eVision2 family with screen sizes of 7” and 10.4” (fig. 03 centre and right). The eVision2 displays provide optimum readability with an inte-grated ambient light sensor combined with a high-contrast, low-reflection TFT moni-tor. Another important feature is that the displays have fast boot up times and are quickly ready for operation during the ma-chine start-up process. Both displays offer boot-up times of less than 15 seconds. Powerful and modern graphic processors provide a high quality display, for example with non-vibrating pointers and bar dis-plays. The displays have fixed buttons as standard, but they are also available with a touchscreen.

Effective development, but how?

The developers of a machine, face the chal-lenge of linking all three levels of the pyra-mid (that is, the three categories of an elec-tronic system) in the best possible way to produce a solution optimised for cost, func-tion and time. Because of the system com-plexity and the interdisciplinary relation-ships, today’s machines are developed by people from various disciplines, working in teams. Accordingly, development tools are required that cover the entire range of deve-lopment steps and tasks and link them toge-ther. HYDAC has created a development environment that does precisely that, en-titled MATCH.

MATCH links the development processes of system definition, application program-ming, simulation/test and commissioning. It is also possible to generate a service pro-gram compatible with the developed soluti-on, that can eventually be used in the pro-duction (end of line tests), by customer ser-vice or by workshops. Utilising MATCH ena-bles development documentation to be produced automatically. Safety-related aspects of development are also considered during all stages.

Visitors to Agritechnica and SPS IPC Drives will be able to see the “pyramids of the Modern Age” in the flesh, along with other innovations, at the HYDAC stand: Agritechnica stand 16 A 08, SPS IPC Drives stand 4A-401.

centralised or decentralised system archi-tectures. The HY-TTC 500 family (fig. 02 bot-tom/right) is based on a 32bit micro-con-troller in the latest design and provides 96 inputs and outputs, most of which can be configured flexibly, for example as an input or an output. Devices in this family are sui-table for use as a single controller in a cen-tralised system architecture, for example. The 16bit computer family HY-TTC 50/60/90 (fig. 02 bottom/left) is equipped with 48 inputs and outputs. Controllers of this type are often used in decentralised system architectures and they are particu-larly suitable as single controllers in smaller machines. The I/O expansion modules from the families HY-TTC 30 and HY-TTC 48 (fig. 02 top), with 30 and 48 inputs and outputs respectively, communicate with control de-vices via CANBus.

As controllers and I/O expansion mo-dules can be combined in all kinds of ways, developers are able to realise all desired system architectures. The controllers and I/O expansion modules are available in a standard version and also in a version with increased safety functionality, dependent on the safety level that needs to be achie-ved. The control devices can be program-med in either C or CODESYS.

The interface between human and machineThe top level of the pyramid contains all components that are required for commu-nication between operator and machine.

Choosing the right controller

The central level of the pyramid is the con-troller, which uses application software to perform the individual machine functions. There are many parameters that need to be taken into account when choosing a suita-ble controller. In addition to the require-ments for robustness (such as environmen-tal influences), the selection is mainly de-termined by factors that relate to applica-tions and development. The required safety level is based on the results of the risk anal-ysis for each individual machine function. This requirement has a major effect on the machine’s system design and on the selec-tion of the required components. With re-gard to the controller, this affects not only the required controller hardware but also the software that the developer is required to create to meet the specifications and reg-ulations. The number of inputs and outputs required for the controller is based on the system design. The design also determines which electrical signals are necessary and what power levels the output signals re-quire. The decision to implement a central-ised or a decentralised control architecture, is based on the machine type and perhaps the machine manufacturer’s preference for a particular system structure. In a central-ised architecture, all inputs and outputs are brought to a central control device. In a de-centralised architecture, on the other hand, the control devices are normally positioned close to the actuators, communicating with each other via digital interfaces. Data trans-fer is still primarily performed via CAN net-works. I/O expansion modules are generally used to compensate for shortfall of inputs and outputs. The computing power that the controller needs is determined by the num-ber and complexity of the machine func-tions. Another major selection factor is which programming language the develop-er is to use to create the application soft-ware. The most popular languages for ma-chine developers are currently C and COD-ESYS.

Prepared for all situations

HYDAC’s control technology range has been developed on the basis of the above requirements. In a joint venture developed under the name “TTControl”, HYDAC has developed an extensive and powerful prod-uct portfolio in conjunction with the Austri-an company TTTech, a technological leader producing robust, network based safety controllers.

Various controllers with a variety of per-formance features are available to develop

tecture, the angle is measured by a Hall sensor, and achieves a safety level of PLd or SIL2. The HAT 1000 offers a resolution of 12bit in its version with an analogue output signal, and 14bit in the CANopen signal version. The modular housing de-sign provides multiple options for con-nection to the mechanical system. Sen-sors with an installed shaft are most com-monly used. If a greater resolution is re-quired, the angle sensor HAT 3000 with 16bit (analogue) and 18bit (CANopen) can be used as an alternative.

The two other sensors are pressure transmitters. The HDA 8000 (fig. 01 top/left) has a self-diagnostic function. Throughout normal measurement opera-tion, constant checks are performed to ensure that the device is functioning cor-rectly. If a fault occurs, the 4 to 20 mA out-put signal is reduced to roughly 2 mA to signal a fault to the controller. This func-tionality allows a sensor problem to be identified and diagnosed clearly.

The second pressure transmitter (fig. 01 centre/left) has been developed for ma-chine functions with increased safety re-quirements. The redundant structure (cat-egory 3) includes two separate sensor cells, which allows a safety level of PLd to be achieved. The measurement values are output as a 4 to 20 mA signal.

An example of this is the position sen-sor HLT 700 (fig. 01 below), which can be integrated into a small cylinder. It measures the position of a ring magnet that is located in the cylinder rod and mo-ved by the piston along the 8 mm diame-ter measuring rod. The evaluation elec-tronics is located in the sensor head, which has a diameter of only 20 mm. With regard to the output signal, the user can choose between voltage, current or CA-Nopen.

HYDAC also supplies a differential pressure transmitter HPT 500, which is used in applications such as load sensing circuits (fig. 01 centre/right). The meas-urement principle involves a spring-mounted piston monitored by a Hall sensor. The HPT 500 offers good reso-lution and measurement precision in re-lation to the differential pressure, even at high operating pressures. The measure-ment signal is output in the form of an an-alogue voltage or current.

The Pyramids of the Modern AgeA look at the electronics in a mechatronic system

Ralf Leinenbach

It was back in the early 80s that automation technology began using the image

of a pyramid to represent a machine’s system architecture. This multi-level model

also applies to the mechatronic systems of a mobile working machine. HYDAC has

been supplying components and systems for such applications for over 50 years.

Halle Stand 16 A08

Halle 4AStand 401

Major sector trade fairs, such as the upcoming Agritechnica, reveal the

current state of progress in the race to find increasingly more productive working ma-chines with state-of-the-art operability, high efficiency, the highest possible us-er-friendliness and the integration into higher-level communication systems, all in compliance with existing regulations and standards, such as those concerning safety. These challenges call for increas-ingly complex systems that machine man-ufacturers can only realise with the help of suitable components, and also experi-enced development partners. The range of services offered by HYDAC has met these requirements for over 50 years. With an ever increasing range of suitable compo-nents, subsystems and systems and many years of application experience, HYDAC has further developed as a supplier and development partner for electrohydraulic systems.

Mechatronic systems can be split up in-to three categories: mechanics (which in-cludes actuators such as valves) electrics/electronics (which includes sensors and controllers) and informatics (which main-ly involves the application software). The text below mainly covers requirements and solutions for the electrical/electronic categories.

Robust sensors

The sensors are located at the bottom level of the pyramid as the direct interface to the working process. They provide the informa-tion a machine needs to carry out its tasks, with the desired precision and quality and

applicable safety. In most mobile working machines, it is mainly the physical meas-urements of pressure, distance, angle, incli-nation and temperature that are measured. In addition to sufficient precision and long-term stability, the sensors need to be ade-quately robust for the particular applica-tion. Disturbances in the process such as highly dynamic pressure peaks and envi-ronmental influences such as electromag-netic radiation, vibration, shock, tempera-ture change and humidity must not impair the sensor function. The sensors must be designed to meet these requirements: from the suitability of the sensor element for the application and reliable electronics assem-bly, to the installation and suitable electri-cal interface.

In mobile applications in particular, cus-tomer tests are required to be carried out according to specifications that often greatly exceed those of conventional standards. The electrical connections (the connector and cable harness) are impor-tant system components that need to be appraised as part of the reliability analysis, although they are often neglected in prac-tice. Many of the problems associated with the sensors or the downstream controller are caused by connection faults. If the ma-chine-type risk analysis reveals that ma-chine functions need to be performed with increased safety levels, this requirement will also affect the sensors. As the com-plexity of the system architecture increas-es, so does the number of sensors with in-creased functional safety increase, such as PLd, SIL2, AgPLd, resulting in more sen-

Both displays offer boot-up times of less than 15 seconds. Powerful and modern graphic processors provide a high quality display, for example with non-vibrating pointers and bar dis-plays. The displays have fixed buttons as standard, but they are also available with a touchscreen.

Effective development, but how?

The developers of a machine, face the chal-lenge of linking all three levels of the pyra-mid (that is, the three categories of an elec-tronic system) in the best possible way to produce a solution optimised for cost, func-tion and time. Because of the system com-plexity and the interdisciplinary relation-ships, today’s machines are developed by people from various disciplines, working in teams. Accordingly, development tools are required that cover the entire range of deve-lopment steps and tasks and link them toge-ther. HYDAC has created a development environment that does precisely that, en-titled MATCH.

MATCH links the development processes of system definition, application program-ming, simulation/test and commissioning. It is also possible to generate a service pro-gram compatible with the developed soluti-on, that can eventually be used in the pro-duction (end of line tests), by customer ser-vice or by workshops. Utilising MATCH ena-bles development documentation to be produced automatically. Safety-related aspects of development are also considered during all stages.

Visitors to Agritechnica and SPS IPC Drives will be able to see the “pyramids of the Modern Age” in the flesh, along with other innovations, at the HYDAC stand: Agritechnica stand 16 A 08, SPS IPC Drives stand 4A-401.

centralised or decentralised system archi-tectures. The HY-TTC 500 family (fig. 02 bot-tom/right) is based on a 32bit micro-con-troller in the latest design and provides 96 inputs and outputs, most of which can be configured flexibly, for example as an input or an output. Devices in this family are sui-table for use as a single controller in a cen-tralised system architecture, for example. The 16bit computer family HY-TTC 50/60/90 (fig. 02 bottom/left) is equipped with 48 inputs and outputs. Controllers of this type are often used in decentralised system architectures and they are particu-larly suitable as single controllers in smaller machines. The I/O expansion modules from the families HY-TTC 30 and HY-TTC 48 (fig. 02 top), with 30 and 48 inputs and outputs respectively, communicate with control de-vices via CANBus.

As controllers and I/O expansion mo-dules can be combined in all kinds of ways, developers are able to realise all desired system architectures. The controllers and I/O expansion modules are available in a standard version and also in a version with increased safety functionality, dependent on the safety level that needs to be achie-ved. The control devices can be program-med in either C or CODESYS.

This communication is still mainly per-formed via mechanical buttons, pedals, joy-sticks, lamps and displays – partly with op-erator input functionality. This is another area in which technological advances will create new communication options, such as assistance systems that are controlled by speech.

The HYDAC HMI portfolio includes the G-pro joystick (fig. 03 left). In addition to its remote control transmitter function, it pro-vides the option of controlling hydraulic valves or alternative actuators. It has 6 PWM outputs and 3 switching outputs that can be used for this purpose.

In mobile working machines, it is par-ticularly important for the information on the screen to be easily recognisable, espe-cially given that ambient light conditions can widely vary. HYDAC meets these de-mands with its devices from the eVision2 family with screen sizes of 7” and 10.4” (fig. 03 centre and right). The eVision2 displays provide optimum readability with an inte-grated ambient light sensor combined with a high-contrast, low-reflection TFT moni-tor. Another important feature is that the displays have fast boot up times and are quickly ready for operation during the ma-chine start-up process.
