Definitions

  • the invention relates to a device for transmitting control signals according to the preamble of claim 1.
  • Such devices form the interface between a bus line and above valves to be controlled and set serial signals to that extent via the bus system are transmitted in binary signals by the valve as control signals are usable.
  • control signals are usable.
  • bus signals are decoded directly on the valve to be controlled by means of a decoding chip assigned to the valve.
  • This solution for the transmission of control signals to the valve has the advantage that the bus line can be looped through from valve to valve and that the wiring effort for the valves is kept very small.
  • connection elements essentially consist of an elongated cuboid housing with at least one connection for the electromagnet of a valve, an optical operating status indicator and electrical contact means arranged on the housing for connection on the input and output sides to further connection elements.
  • Their job is to record the decoding electronics and driver electronics for converting the control signal into a switching signal for the electromagnet, which serves as an actuator for the valve, and to loop the bus line through to the next connection element.
  • they have internal wiring that is geared towards serial data transmission in the bus system.
  • the invention has for its object a device for transmitting To create control signals between the bus line and valves with a compared to the prior art, reduced expenditure on electronic Components manages and at the same time keeps the wiring effort low.
  • the invention includes the technical teaching for the transmission of Control signals from the bus line to the valves to be controlled to be provided, which are each assigned to a valve.
  • the connection elements are in connected in series and are divided into active connection elements and passive connection elements.
  • the active connection elements have decoding electronics in Form of a decoding chip.
  • the decoding chip is on the input side with the bus line connected and has connections on the output side for controlling valves. At least one connection is made via the active connection element to the associated valve guided. The other connections are made over the passive Connection elements with the associated valves electrically connected.
  • This Integration of the bus electronics in an active connection element offers the advantage that central decoding electronics on the valve unit can be dispensed with entirely.
  • the partially decentralized principle of the invention enables Arrangement of the decoding electronics the economical use of only one decoding chip for multiple valves.
  • the use of connectors instead of one Exposed wiring for forwarding the control signal to the valves also avoids any manual wiring and allows one modular design.
  • passive Connection elements used, which are preferably each assigned to a valve. All passive connection elements have staggered internal wiring, so that the control signal for the valves through the passive connection elements to the each valve to be controlled can be passed, the individual passive Connection elements have the same internal wiring and in this respect also are interchangeable.
  • connection elements again to activate an active connection element, via which again at least one valve itself and subsequent ones above it passive connection elements other valves can be controlled.
  • the number of passive Connection elements that can connect behind an active connection element is limited by the number of decoder chips on the active connection element Available connections for the operation of valves.
  • an emergency stop line through all Lead connecting elements.
  • This emergency stop line supplies the devices to be controlled Valves with the operating voltage. It is part of a safety-related Facility. If the emergency stop line is interrupted from a central switch, this causes the actuators of the entire system to come to an immediate standstill the valves are operated without the current switching state of the Control electronics is lost. This means that the system can be restarted safely possible.
  • the first valve 7 is via the active connection element assigned to it 3 and connected via a junction box 2 to a two-pole bus line.
  • An AS-Interface bus is the bus system for the preferred embodiment variant of the invention provided, as this bus standard especially for the control of the machine Binary elements - such as relays, switches or valves - have been designed and so far Particularly suitable for use as a fieldbus in the area close to the valve.
  • the AS-Interface bus standard only allows serial data transmission via one two-pole bus line, which enables economical cabling.
  • the serial bus signals into binary control signals for the solenoids of the valves houses the active connection element as a decoding chip an AS-Interface chip 19. This receives the bus signals on the input side and is capable of using its four Ports that are initialized so that they form four outputs to control four valves.
  • the first valve 7 is connected directly to the active connection element 3.
  • the second Valve 8 is behind its active connection element 3 via its passive connection element 4 switched.
  • the third valve 9 and the fourth valve 10 follow this via their passive connection elements 5 and 6 in the same way. So the four outputs are of the AS-Interface chip 19 occupied.
  • valves can be activated via a next active connection element 11, which is itself assigned to the valve 13 and on the input side to the fourth passive connecting element 6 connects, be connected. Then you can again a valve 14 via a passive connection element 12 and a further three passive connection elements and thus three valves are operated.
  • the limit of AS-Interface standards is 19 with a maximum of 31 connectable AS-Interface chips an AS-Interface bus line 1 is reached.
  • an AS-Interface chip 19 is the integration of an AS-Interface chip 19 into an active connection element is shown in FIG 2 shown.
  • Pin1 and Pin2 is the contacts 16 on the input side to the two-pole emergency stop line 15. This is looped through to the corresponding output contacts 17.
  • Pin3 and Pin4 of the input-side contacts 16 are with the two-pole AS-Interface bus line 1 connected. This is also exactly the same as the corresponding one output-side contacts 17 of the connecting element looped through.
  • the AS-Interface chip 19 accesses the serial bus signal on the input side by the active one Connection element looped bus line.
  • the first of a total of four Outputs is with the valve assigned to the active connection element via the electrical valve connection 18 connected.
  • the other three outputs of the AS interface chip are in turn at Pin5, Pin6 and Pin7 on the output side Contacts 17 out.
  • FIG. 3 shows a further advantageous internal connection of the AS-Interface chip 19 with an active connection element.
  • This connection element points as Special feature two connections 18 for controlling valves. So that in Difference from the variant described above for controlling a valve with a connection element, only a similar passive one Connection element or two passive connection elements, each with a valve connection be operated via the associated active connection element, so that the To fully utilize the connection capacity on the AS-Interface chip.
  • Figure 4 shows the internal wiring of a passive connection element for operation of a valve.
  • Pin1 to Pin4 of the input contacts 16 are exactly the same as the pins output-side contacts 17 connected to the bus line 1 and the emergency stop line 15 by the connecting elements connected in series in a row Lead valve unit.
  • Pin5 of the input contacts 16 goes to the Valve connection 18.
  • Pin6 and Pin7 of the input-side contacts 16 are of this type offset connected to the output contacts 17 that they are there at Pin5 or go to pin 6.
  • Every passive connection element contains as well as every active one Connection element a driver transistor, not shown in the figures, the the control signals the operating voltage for the valve, which is from the emergency stop line is tapped, switches.
  • FIG. 5 Another variant for wiring the passive connection element for the Operation of two valves is shown in Figure 5.
  • Pin7 of the input side Contacts 16 is connected to pin 5 of the output contacts 17.
  • the individual active and passive Connection elements for operating one valve alternately from an active one Connection element 3 and three passive connection elements 4, 5, 6 via the contacts 16 and 17 connected in series results in the preferred one according to the invention Embodiment of the device for transmitting control signals from the AS-Interface bus line 1 to a valve unit.
