We’re using three different EQU instructions to demonstrate the capabilities of the instruction. The Integer N7:4 is currently set to “0” while the Counter “Accum” Value C5:0.ACC is set to “0”.An EQU instruction is used to compare a Counter “Accum” Value C5:0.ACC to the Integer N7:4.This EQU instruction evaluates to TRUE.The Integer N7:2 is currently set to “0” while the Integer N7:3 is set to “0”.An EQU instruction is used to compare an Integer N7:2 to the Integer N7:3.This EQU instruction evaluates to FALSE.The Integer N7:1 is currently set to “0” while the constant is set to “7”.An EQU instruction is used to compare an Integer N7:1 to a constant.A Micrologix 1100 Allen Bradley PLC is used to control a process.Here’s a real-world scenario of an EQU instruction: That being said, this isn’t the recommended practice as you’ll need to edit the program and commit the edit if you want to change the said value. Furthermore, you may choose to use to enter a fixed value instead of an operand tied to a tag. The instruction is very versatile as you can use integers, floats and even user-defined tags in certain programming environments as operands. It’s commonly used to check if a certain limit has been met, if a counter reached a certain value or if a certain alarm has been triggered. The EQU instruction is critical within the Automation world as it’s the only way to see if the values are completely identical. Should they become unequal, the instruction will update on the next PLC scan. The EQU will compare the two values and only evaluate to true is the two integers are equal. If that condition is met, the instruction will allow what’s on the right of it to execute. The EQU instruction is an input instruction which will return TRUE if the two values within “Source A” and “Source B” fields are equal to each other. Send us feedback about these examples.The EQU, also known as the Equal, instruction is used to compare two values. These examples are programmatically compiled from various online sources to illustrate current usage of the word 'equation.'

Allison Aubrey, CBS News, 9 July 2023 But political expediency may also be part of the equation, analysts say. Javier Zamora, Los Angeles Times, 10 July 2023 And the amount of feed that goes to feed animals, to feed us, that equation just seemed wrong. Mira Miller, Verywell Health, 10 July 2023 There is infinite room for nostalgia to enter the equation from the U.S. Andre Gee, Rolling Stone, 11 July 2023 Acid weakens the tooth’s protective enamel, and adding abrasion to the equation can damage it, Tasios explained. Dj Siddiqi, Forbes, 17 July 2023 While Her Loss is more like a Drake solo project marketed as a collaboration, 21’s presence does at least offer some balance to the equation. Stephanie Breijo, Los Angeles Times, 19 July 2023 Go Viral With Elliott out of the equation, Pollard will enter the 2023 season as the unquestioned starting running back for the Cowboys. Dac Collins, Outdoor Life, 19 July 2023 Michelin’s exact scoring criteria remain as elusive as its inspectors’ identities, although qualities such as consistency are always part of the equation. Of course, physical needs are only part of the equation when trying to survive in the open ocean. Recent Examples on the Web Read Next: 10 Primitive Survival Skills that Will Keep You Alive
