Rubix Wires: Latch Nodes


This article describes the Rubix Wires nodes that are in the Latch category.

Latch

The `Latch` category contains value latching functionality for each data type.  Latch nodes will maintain an output value between trigger events.

Any-Latch

This node can take any input data type compared to the other latch nodes than can only take specific data types.

Inputs

  1. input - Input value of any data type.
  2. latch - Boolean trigger for the latch operation.

Outputs

  1. output - Output value of any data type.

Settings

  1. Name - Name of the node.
  2. Only if input value is updated - Toggle switch to

Operation

The  'input' value is passed to 'output' when 'latch' transitions from 'false' to 'true'; The 'output' value is maintained until the next 'false' to 'true' transition.

Bool-Latch

This node takes a boolean input value and outputs (and maintains) the boolean value when latch is triggered.

Inputs

  1. input - Boolean input value.
  2. latch - Boolean trigger for the latch operation.

Outputs

  1. output - Boolean output value.

Settings

  1. Name - Name of the node.

Operation

The Boolean 'input' value is passed to 'output' when 'latch' transitions  from 'false' to 'true'; The 'output' value is maintained until the next  'false' to 'true' transition.

Num-Latch

This node takes a numeric input value and outputs (and maintains) the numeric value when latch is triggered.

Inputs

  1. input - Numeric input value.
  2. latch - Boolean trigger for the latch operation.

Outputs

  1. output - Numeric output value.

Settings

  1. Name - Name of the node.

Operation

The Numeric 'input' value is passed to 'output' when 'latch' transitions  from 'false' to 'true'; The 'output' value is maintained until the next  'false' to 'true' transition.

String-Latch

This node takes a string input value and outputs (and maintains) the string value when latch is triggered.

Inputs

  1. input - String input value.
  2. latch - Boolean trigger for the latch operation.

Outputs

  1. output - String output value.

Settings

  1. Name - Name of the node.

Operation

The String 'input' value is passed to 'output' when 'latch' transitions  from 'false' to 'true'; The 'output' value is maintained until the next  'false' to 'true' transition.

Set-Reset

This node outputs a latched boolean value based on boolean `set` and `reset` inputs.  (ref: https://en.wikipedia.org/wiki/Flip-flop_(electronics)#Simple_set-reset_latches).  This node is commonly used to implement staging logic that is based on Stage-UP and Stage-Down conditions.

Inputs

  1. set - Boolean SET input.
  2. reset - Boolean RESET input.

Outputs

  1. output - Boolean output value.

Settings

  1. Name - Name of the node.
  2. Reset when set=true - When enabled `output` will always be `false` while `reset` is `true`.  When disabled `output` will always be `true` when `set` is `true` (even when `reset` is `true`).

Operation

‘output' will be 'true' when 'set' is 'true', and 'reset' is 'false'.
There are 2 cases when 'output' will change to 'false':
  1. 'reset' is 'true', and 'set is 'false'.
  2. If the 'Reset when set=true' setting is turned ON (Default),  and 'reset' and 'set' are both 'true'.  If 'Reset when set=true'  setting is turned OFF, 'output' will only change to 'false' under  Case 1) conditions.
