Definitions

  • the present invention relates to a bench-testing device for industrial control systems. More particularly, the present invention relates to a testing device to 5 be used during the factory-testing of industrial control systems.
  • the configuration software of industrial control systems usually uses a testing panel of the hardware type. This panel, after being set up, is physically it) connected to the input and output boards of the control system to be tested and allows closing the control and regulation loops to be tested.
  • the hardware panel is generally constituted by:
  • potentiometers for replicating the analog signals (e.g. 4-20 mA signals) from the plant (for example level, pressure, position, flow-rate, temperature
  • switches for replicating the digital signals e.g. 0-24 V.
  • switches for replicating the digital signals e.g. 0-24 V.
  • amperemeters for replicating the actions of the analog actuators provided in the plant (for example valve regulations, motor rpm-rate adjustments and the l ike );
  • each one of the devices provided on the hardware panel is assigned with a specific function among those provided in the plant portion to be tested ( valve, switch, transducer, actuator, etcetera).
  • Each one of these 5 devices is then connected, by means of dedicated cables, to the specific channel of a given acquisition (input) or control (output) board of the control system, so as to close the control loops provided by the designer of the control system. In this way the control system is tested before physically implementing it in the field.
  • the operators involved in the control system testing work check on the hardware panel that the commands issued by the controller are correct (lighting of lamps and indication of amperemeters) and provide the controller with the appropriate signals which, during normal operation, would arrive from the plant (potentiometers and switches).
  • connection between the control system to be tested and the conventional testing panel is provided by means of electrical cables.
  • This entails the need for considerable time in order to provide and check the connection of any input and/or output channel of the control system to the various elements of said panel, in addition to requiring bulky wiring.
  • Another drawback is due the fact that the testing of control systems is always performed by individual plant portions for complexity reasons. Any time the testing of a new plant portion begins it is necessary to reassemble and reconnect the hardware panel, which is accordingly scarcely flexible in relation to the continuous modifications that are required when testing a plurality of plant sections in succession. Errors are unavoidably made during the preparation of the testing panel and during its subsequent connection to the control system and are added to the errors already present in the configuration software of the controller.
  • the conventional testing bench does not facilitate the execution of all the necessary operations. For example, the action of stopping a pump, with the consequent closure of the intake and delivery valves and with an interlocking action with respect to other plant portions, results quite complicated. In fact, it entails that one or more operators must operate various devices of the panel and constantly monitor both the indications of the panel and the information from the control system.
  • the aim of the present invention is to provide a testing device, for industrial control systems, which allows eliminating conventional hardware test benches and control system-specific software programs. It must allow, at the same, editing a model of the components of the plant to be tested and 5 therefore perform its factory testing.
  • an object of the present invention is to provide a testing device, for industrial control systems, which allows preparing, in an assisted and reusable manner, a software bench.
  • the software bench is aimed to test industrial control systems and allows defining the structure of the plant o portion being controlled independently of the hardware/software platform used.
  • Another object of the present invention is to provide a testing device, for industrial control systems, which allows reducing the time and cost entailed by factory testing, which is compulsory before the field installation of an industrial control system. 5
  • Another object of the present invention is to provide a testing device, for industrial control systems, which allows eliminating the operations for wiring and assembly a conventional hardware panel to the control system to be tested, and therefore the costs arising from the construction of said hardware panel.
  • Another object of the present invention is to provide a testing device for o industrial control systems which allows reusing the software bench prepared with the device according to the invention, accordingly offering high flexibility in use.
  • Another object of the present invention is to provide a testing device for industrial control systems, which allows to evaluating much more complex ⁇ control logic systems than allowed by a conventional testing panel.
  • the present invention provides a testing device for industrial control systems, comprising:
  • Figure I is a block diagram of the testing device according to the present invention.
  • Figure 2 is a block diagram of the use of the testing device according to the invention, connected to a plant control system.
  • the testing device consists of a device which is suitable to create a model of the components of an industrial plant, which exchanges information with a control system (prepared for the industrial plant).
  • the testing device according to the present invention is also suitable to execute the resulting model in order to directly factory-test said control system.
  • the testing device designated by the reference numeral 1 , comprises, as shown in Figure 1 , editing means 2, which allow composing a software test bench by assembling various models taken from storage means 4.
  • editing means 2 By way of said editing means 2, it is also possible to connect all the input and output signals exchanged between the control system and the plant, rerouting them onto the bus of the control system, with the inputs and the outputs of the models used.
  • the editing interface means allow performing the following functions: - preparing a new plant model (20);
  • the testing device is further provided with modeling means 3, which provide functions suitable to guide and facilitate the testing engineer in synthesizing a simplified model to be used for testing particular control loops. If the loops to be tested are standard (for example pump control, simple adjustment loops, etcetera), modeling means allow advantageously the testing engineer to simply input few parameters that characterize the individual loop and to compose semi-automatically the software test bench part related to the testing of said loops.
  • the modeling means 3 therefore comprise functions 27 for individual loops, functions 28 for cascaded loops and functions 29 for modeling driving devices such as valves or motors or the like.
  • the testing device further comprises, as mentioned, storage means 4 which are meant to provide the testing engineer with a plurality of pre-wire models for closing the loops to be tested.
  • the storage means 4 can be represented, for example, by libraries of plant models. These models allow, for example, emulating plant responses. For example, when testing the drive of a pump, time delays might be used to obtain plant response emulation.
  • the models contained in the storage means 4 are therefore constituted by input-output functions with 1 -2 poles, or in algebraic relationships, or by pure delays, so as to give the feedback signal from the plant a minimum of dynamic range.
  • the models available can be, for example, regulation and/or on/off valves 30, > pumps and/or motors 3 1 , analog indications (for example levels, flow-rates, positions) and/or digital indications (for example pressure switches, level switches, limit switches) 32.
  • the device according to the invention further includes a simulation engine 5, which is meant to process the simplified models. It constitutes the feedback to the control system 10 and is connected to lo the inputs and outputs of the control system, appropriately re-routed on the bus 12 of the controller 13.
  • the simulation engine 5 accordingly receives in input the structure of the plant components, produced by the testing engineer by using the models of the storage means 4. made available within the testing device 1 .
  • the hardware means 6, suitable to interface the testing device to a specific industrial control system 10 are meant to exchange the input and output signals of the control system 10 rerouted on the control bus 12 of the control system 10.
  • Said means 6 must be designed specifically for the control bus 1 2 to which the test bench provided by the device according to the in invention connects and specifically for the data exchange protocol used by the specific control system 10 that is used.
  • the reference numeral 10 designates the control system of a plant, which is generally designated by the reference numeral 1 1 .
  • the reference numeral 1 2 designates the control bus, which carries signals to controllers 13 5 and to I/O cards 14 of the control system 10.
  • the control bus is connected to interface means 6 which allow to connect the testing device 1 to the control system 10.
  • the testing device 1 shown in Figure 2 is understood to include the editing interface means 2 and the means 3-5 described hereafter in detail and shown in Figure 1 .
  • the testing device according to the invention therefore can be, in practice, implemented by means of a computerized system, which can be connected to ⁇ the control bus 12 of the industrial control system 10 through the interface means 6.
  • the monitor, the keyboard and the mouse of the computerized constitute the tools that can help the basic editing and modeling functions available.
