Compare Value

Overview

The Compare Value node evaluates a primary input against a comparison value and outputs a boolean result. It supports static values or dynamic comparison through a second input port.

Use Compare Value when:

• Triggering an event based on a threshold (e.g., number of defects > 0).
• Checking if a status string matches a specific value.

💡 Tip

This node can also compare text inputs using the == (equals) and != (does not equal) operators. The input port type will automatically adjust based on the connected signal.

Inputs

Name	Type	Description
input	number or string	The primary value to be compared.
compare_to	number or string	Optional second value for comparison (enabled via Enable compare input).

Outputs

Name	Type	Description
output	bool	The boolean result of the comparison.

Parameters

Parameter	Default	Valid values	Tunable
Comparison value	0.0	number/string	✅
Operator	==	==, !=, <, >, <=, >=	❌
Enable compare input	false	bool	❌

Comparison value

The static value used for comparison when Compare input is disabled.

Operator

The mathematical or logical rule applied to the inputs.

Enable compare input

When enabled, the node adds a compare_to input port and ignores the static Comparison value.

Example

Overweight Product Detection

A packaging system uses a Compare Value node to ensure that a product does not exceed the maximum allowable weight.

Configuration:

• Comparison value: 10
• Operator: >
• Enable compare input: false

Result: The measured product weights 12 kg. Since 12 > 10, the output is true, indicating that the product exceeds the weight limit and should be rejected.
