2.1 Inputs

Two-Hand Device

Block diagram — Two-Hand Device

This block can be used for a Two-Hand device input according to EN 574.

Pins: 2 or 4

Inputs: None

Outputs

  • ON — 1 (HIGH) when the function is in the ON-state, which is when all pins receive their configured ON-state signal type and all timing requirements are met. It is 0 (LOW) when any criteria for the function to be in the ON-state are not met.
  • ERROR — 1 (HIGH) when the function is in the ERROR-state.

Properties

  • Name — specify a unique name for this block.
  • Error output — enables or disables the error output connector.
  • Filter ON — filters the 0→1 flank of pins, so they must be in the ON-state for longer than this time.
  • Filter OFF — filters the 1→0 flank of pins, so they must be in the OFF-state for longer than this time and cannot be changed.
  • Enable simultaneity (read only) — enables simultaneity checking.
  • Simultaneity (read only) — simultaneity is set to 0.5 seconds and cannot be changed.
  • OFF state min time — if enabled, requires all pins to be in the OFF-state for this time before the function can go to the ON-state.
  • StartUp Test (read only)
  • Pins — the following settings can be changed for each pin:
    • Pin — the pin number to use for this pin input.
    • OFF — which signal type should be considered as the OFF-state.
    • ON — which signal type should be considered as the ON-state.

Status Input

Block diagram — Status Input

This block can be used to evaluate a status signal input and use it in logic.

Pins: 1

Inputs: None

Outputs

  • ON — turns on when a logical HIGH analogue signal is received on the configured pin. Note that this output is an unsafe signal.

Properties

  • Name — changes the name of this block.
  • Pin — the pin number to use.

Selector

Block diagram — Selector

This block can be used to evaluate a selector switch input. The switch can be of different types: Single NO, Double NO, Double NC/NO.

Pins: 1–2

Inputs: None

Outputs

  • ON — 1 (HIGH) when the selector switch is in the state.
  • ERROR — 1 (HIGH) when the function is in the ERROR-state, and 0 (LOW) if the function is in the ON or OFF-state.

Properties

  • Name — sets the name of the block.
  • Error output — enables the error output.
  • Enable simultaneity — enables simultaneity checking on this function.
  • Filter ON — filters the 0→1 flank of the pins.
  • Filter OFF — filters the 1→0 flank of the pins.
  • StartUp-test — enables or disables the StartUp test check. If StartUp Test is enabled, the function cannot go to the ON-state directly at start-up (power on) but needs a valid OFF-state first.
  • Pins
    • Mode — changes which input type this block is (Single NO, Double NO, Double NC/NO).

Advanced Input

Block diagram — Advanced Input

This block can be used to create a custom input function to fit a specific device or application. The input function is described in 1.15 Input Functions.

Pins: 1–8

Inputs: None

Outputs

  • ON — 1 (HIGH) when the function is in the ON-state, and 0 (LOW) when the function is in the OFF-state or ERROR-state.
  • ERROR — 1 (HIGH) when the function is in the ERROR-state, and 0 (LOW) if the function is in the ON or OFF-state.

Properties

  • Name — sets the name of the block.
  • Error output — enables the error output connector.
  • Filter ON — filters the 0→1 flank of the pins.
  • Filter OFF — filters the 1→0 flank of the pins.
  • Enable Simultaneity (ms) — enables or disables simultaneity.
    • Simultaneity (ms) — all pins must go to the ON-state within this time for the function to go to the ON-state. If this fails, the input needs all pins to go to the OFF-state before a new attempt can be made.
  • Enable Zero Time — enables or disables the Zero Time property.
    • Zero Time (ms) — if enabled, requires all pins to be in the OFF-state for this time before the function can go to the ON-state.
  • StartUp Test — enables or disables the StartUp test check. If StartUp Test is enabled, the function cannot go to the ON-state directly at start-up (power on) but needs a valid OFF-state first.
  • Pins
    • Mode — specifies how many pins should be used in this function (between 1 and 8).
    • Pins — the following settings can be changed for each pin:
    • Pin — the pin number to use for this pin input.
    • Signal Type ON — which signal type should be considered as the ON-state.
    • Signal Type OFF — which signal type should be considered as the OFF-state.
    • Invert — switches the ON and OFF signal types. This can, for example, be used to create an NC/NO input.

Safety Switch

Block diagram — Safety Switch

This block can be used to evaluate a door or gate sensor dual input.

Pins: 2

Inputs: None

  • StartUp Test — enables or disables the StartUp test check. If StartUp Test is enabled, the function cannot go to the ON-state directly at start-up (power on) but needs a valid OFF-state first.
  • Simultaneity — defined to 500 ms and cannot be changed.
  • Filter ON (ms) — filters the 0→1 flank of pins, so they must be in the ON-state for longer than this time.
  • Filter OFF (ms) — filters the 1→0 flank of pins, so they must be in the OFF-state for longer than this time and cannot be changed.

Light Curtain

Block diagram — Light Curtain

This block can be used to evaluate a Light Barrier/ESPE input device.

Push Button

Block diagram — Push Button

This block can be used to evaluate a single-input push button with an indication output on the same pin (for example a reset/start push button with indication). This is accomplished by quickly switching between using the transistor I/O as an input and an output (1.5 ms output, 0.5 ms input).

Safety Strip 8.2 kΩ

Block diagram — Safety Strip 8.2 kΩ

This block can be used to evaluate the state of a safety strip with an 8.2 kΩ resistor at the end. It goes to the OFF-state when the safety strip is pressed, and the ON-state when the safety strip is not pressed. If the safety strip is disconnected, the function goes to the ERROR-state. Reconnecting the safety strip requires it to be pressed once to verify the OFF-state, and then released to go to the ON-state.

Inputs: None

Outputs

  • ERROR — 1 when the safety strip is disconnected.

Properties

  • Name — sets the name of this block.
  • Enable ERROR output — enables the error output.
  • Pin — which terminal the safety strip is connected to.
