Definitions

  • the invention relates to a multi-pin connector for connecting an input / output unit to a machine control according to the preamble of claim 1.
  • a connector is z.
  • Modular control systems are in the manufacturing industry for manufacturing equipment, transport equipment or the like. Necessary. They have to be carefully planned and created and, especially when upgrading the production facilities, permit extensions. This is achieved by fixed power and data lines to which an interface card can be connected at any point along its length, which can be connected via input / output modules and I / O units such as actuators, sensors, or the like.
  • connection of an actuator to the data bus takes place in a different way than the connection of a sensor.
  • a sensor reports signals to the data bus, so it is queried from the data bus.
  • An actuator is acted upon via the data bus with a control signal; usually an actuator is actuated by switching an electric current.
  • control signals are thus transmitted from the data bus to the actuator.
  • the design, planning and installation of the system must therefore be carried out depending on the actuators and sensors used. This is expensive and especially disturbing when exchanging slots during conversion or upgrading the system and actuators must be connected instead of sensors or vice versa.
  • an electronic, operated by the terminal unit switch is arranged for free parameterization of a pin of a connector between the pin and a terminal unit.
  • the pin is connected to a fieldbus via the electronic connection unit, with the pin optionally being connected as a signal input for a sensor, as a control output for an actuator or as a diagnostic input or diagnostic output.
  • the invention has for its object to form a multi-pin connector for connecting an input / output unit to a machine control such that the connection of different input / output units is easily possible.
  • the multi-pin connector with four contact pins, a terminal unit and arranged between the terminal and the contact pins switches via the electronic terminal unit connects to the data bus, wherein the same contact pin of the terminal unit can be switched either as a signal input for a sensor or as a control output for an actuator can.
  • This electronic conversion is also possible via software directly from the data bus.
  • only one type of connector or a module variant is necessary, which simplifies storage, installation and maintenance.
  • the pin of the connector is alternatively as a function input or diagnostic input and the pin is to be switched as an output or function input.
  • a contact pin as a diagnostic input and / or diagnostic output, so that z. B. a freed pin can be used by the terminal unit as a diagnostic connection.
  • an electronic, operated by the terminal unit switch is arranged, which connects the contact pin depending on the type of the connected I / O unit optionally with a signal input module of the terminal unit or with a control output module and / or with a diagnostic module ,
  • a free parameterization of the connector or the contact pins of the connector is possible, so that in a simple manner by plugging a sensor to an actuator port and vice versa, the connector of the connected unit can be operated accordingly.
  • connection unit must be programmed via the machine control data bus to control the electrical switch according to the connected I / O unit. Therefore, undefined states can be avoided both at start-up of the control and reprogramming to other parameters is possible at any time.
  • the diagnostic module can transmit the evaluated data via the fieldbus to a central monitoring unit;
  • the diagnostic module is connected to display elements, which are expediently designed as LEDs and give the user the opportunity to spot a faulty input / output unit and initiate countermeasures.
  • Occurring error conditions are expedient both signaled on the display unit and transmitted to the data bus. This simultaneous error message on site and to the control center ensures a high level of security.
  • the diagnostic module not only checks the connected unit but can also monitor the line connection to the units or interface. If z. B. on an output a signal and turns in response to a current of z. B. less than 3mA, there is a line break, which is displayed as an "open load" state.
  • Fig. 1 represented interface is part of a machine control and is connected via a power line 1 to a live network and connected via a field bus 2 with the central machine control for the exchange of data and control commands.
  • a power supply 3 is first connected to the power line 1.
  • the power supply unit 3 serves to supply power to individual components to be connected.
  • the connection to the fieldbus 2 is achieved via a preferably active interface card 4 having four terminals 4a, 4b, 4c and 4d for individual components such as a plurality of input / output modules 10, 12 or the like.
  • the modules 10 consist of an M12 plug connection, while the modules 12 consist of an M8 plug connection 6.
  • the modules 10, 12 are fixedly arranged in a holder and connected via a link module 11 and an interface cable 23 to a terminal 4a, 4b, 4c, 4d of the interface card 4.
  • Each connector 6 of the input / output modules 10, 12 is provided as a multi-pin connector for connecting an input / output unit such as an actuator 25 or a sensor 15, which in Fig. 1 are indicated schematically.
  • the contact pins 1, 2, 4 of in Fig. 2 shown connector 6 via an electronic terminal unit 41 and a bus cable 42 are connected to the data bus 2. It is inventively provided that the same contact pin 1, 2 or 4 is to be switched either as a signal input for a sensor or as a control output for an actuator. The same contact pin 1, 2, 4 can also be switched as a diagnostic input and / or diagnostic output.
  • pin 2 and pin 4 can be freely parameterized in the case of an M12 plug-in connection, with pin 2 or 4 being connected, for example, as a digital function input with normally open or normally closed functionality, as a diagnostic input or as a digital output.
  • a parameterization as analog input and output for voltage and current is useful.
  • analog sensors can be used to connect control sensors whose signal voltage or signal current is proportional to a control variable and is, for example, in the range between 0 and 10V or 0 and 20 mA.
  • actuators can be controlled as actuators, so that an analog control signal is applied to the output.
  • an electronic switch 40 is disposed between each contact pin 1, 2, 4 of the connector 6 and the terminal unit 41, which is preferably designed as an IC.
  • the electronic switch 40 is actuated by the terminal unit 41, each individual contact pin 1, 2, 4 depending on the type of the connected I / O unit 15, 25 optionally with a signal input module 30 or - controlled by a control signal output module 31 - with a power supply 33 is to be connected.
  • the connecting unit 41 can also connect each of the contact pins 1, 2, 4 with a diagnostic module 32 for fault detection.
  • the trained especially as IC electronic switch 40 is to control the fieldbus 2 of the machine control via the bus cable 42, so that a connector 6 of an I / O module 10, 12 can be used differently according to the connected via the connector 6 input / output units , Is about the connector z.
  • a bipolar sensor connected, the poles 1 and 2 via the electronic switch 40 and the control / signal lines 43 are connected to the signal input module 30; from the power supply 33, the contact pins 1 and 2 are then disconnected.
  • a diagnosis of the connected sensor can be made so that the contact pin 4 is connected via the IC 40 to the diagnostic module 32.
  • each pin is assigned a yellow LED 34a, 35a as an OK indicator and a red LED 34b and 35b as an error indicator.
  • the terminal unit 41 may be self-detecting, i. h., after connection z. B. a sensor to the connector 6, the terminal unit 41 checks whether a current flows through the connected contact pin 1. If this is the case, the connection is detected as a sensor and the IC 40 is controlled accordingly. A detection of a sensor can also be done by discontinued test signals and incoming electrical feedback.
  • the terminal is to be recognized as an output and to control accordingly by the terminal unit 41 via the IC 40.
  • the actuators can also be monitored via the diagnostic module 32, so that e.g. for a given control signal, the self-adjusting current is monitored. If it is below a threshold of e.g. 3mA, there is a line break, which is displayed as an "open load" state.
  • a creeping occurring overcurrent can be detected with a diagnostic module, so that a kind of advance notice is provided.
  • the user will see too high a current warning of a possible failure in the near future, even though the system is still working properly at the time the overcurrent indicator is activated.
  • the output currents can be set between limit values in the range from 0 to 2A, preferably set variably.
  • the permissible currents can be set as required according to the parameterization so that each pin 1, 2 or 4 can be monitored for the permissible current by the diagnostic module.
  • a pre-failure indicator is generated that reports the overload. The user can thus detect an imminent failure and initiate countermeasures.
