Having said all that, ease of use isn’t always the most important criteria depending on the experience level of the technician and the intended application. Debugging an Allen-Bradley PLC arguably takes less time and effort than it does with a Siemens PLC.įurther, Allen-Bradley PLCs communicate effectively with third-party devices, and can import and export tags from Excel to Human Machine Interface (HMI) or SCADA databases. Ease of use means that even a relatively untried PLC technician without extensive programming experience can still make use of an Allen-Bradley PLC – but the ease of use doesn’t stop there. The Allen-Bradley PLC is known for boasting both of these qualities and that makes this Programmable Logic Controller an appealing investment for any manufacturer. There’a a lot to be said for ease of use and a user-friendly interface. Instead, things like ease of operation and integration are often the main points of differentiation that need to be considered. Unfortunately, making a decision between Allen-Bradley and Siemens based purely on performance isn’t easy they’re both pretty evenly matched when it comes to speed, reliability, and output. When it comes to technology that could revolutionize operations on the factory floor, performance is going to command the lion’s share of attention. Two such PLCs, Rockwell’s Allen-Bradley and Siemens are two of the world’s most widely used PLCs – and while each device is undeniably an industry staple there are a number of key differences between the two of them. Like anything else, not all PLCs are created equal each PLC on the market today has its own list of features and benefits. The fact that this seemingly nondescript industrial box could possibly reign supreme over other transformative technologies developed in the 50’s and 60’s – mainframe computing, personal computers, semiconductors and others – speaks volumes to what PLCs have meant (and continue to mean) for manufacturing in the 20th and 21st centuries.

Of the very long list of industrial technologies that emerged from what has come to be known as the third industrial revolution, the Programmable Logic Controller (PLC) is arguably one of the most impactful. Though it may be hard to believe that industrial automation has been around for nearly 70 years, what’s harder still is that technology is continually finding new and innovative ways to improve production capabilities and process efficiencies.
