Hello everyone, my colleague and I are currently in the process of planning an upgrade for our system's control components, including mixers, water counters, and temperature controllers. Our system mainly involves digital IO, 4-20mA input, and RTD temperature probes, and we anticipate needing at least 300 I/O points. We are interested in hearing about your experiences with ABB's Freelance AC700 and AC900 products. What are your thoughts and reviews on them? My colleague is considering these products due to their affordability (approximately $6k CAD for 300 I/O points), but I personally have had some reservations about ABB's control systems in the past. I have had more positive experiences with products from AB and would prefer them if the price is right. Thank you for your input!
ABB's Freelance DCS system, equipped with the latest controllers AC700F & AC900F, is a top-quality and compact solution. This system, stemming from the trusted Hartmann & Braun brand, offers remarkable backward compatibility and a user-friendly interface. Contact ABB or their representatives for more information and assistance.
Thank you for your support! Your positive feedback is greatly appreciated and motivates us to continue delivering high-quality service. Let us know if there is anything else we can assist with. We value your satisfaction and look forward to serving you again in the future.
When considering the IO count, it may be beneficial to utilize the ABB AC500 with ABB Compact HMI or a third-party SCADA system such as Ignition. In my opinion, I do not favor the AC700 Freelance as much.
If you have a low I/O count, opting for an AC500 system could be a suitable choice based on your specific needs such as redundancy and hot swappable capabilities.

Hey there! I've recently completed a project using ABB's AC900 and from my experience, it's quite a robust system. I was impressed by its seamless integration with different components and simplicity in programming. However, ABB's after-sales service was not as responsive as I would have liked. Normally, I would advise going with what you know and trust, but the cost efficiency of ABB can't be overlooked if budget constraints are a factor. Hope this helps in your decision-making process!
I totally get where you're coming from! I've had my fair share of experiences with both ABB and AB, and while ABB's Freelance systems can be quite cost-effective and flexible, I've also found that the support and ease of integration with Allen-Bradley's offerings tend to be a bit better, especially in complex setups. If your system is going to be critical, it might be worth considering not just the upfront costs but also the long-term support and reliability of the system. Have you looked into any user reviews or case studies on ABB's systems? Sometimes, hearing about real-world applications can really help with the decision!
I've worked with both ABB Freelance systems and Rockwell Automation's products, and I can appreciate your concerns. The Freelance AC700 and AC900 are indeed budget-friendly, particularly for large I/O applications like yours. They offer good flexibility and are relatively easy to integrate, but I've encountered some limitations in software functionality that could be a hurdle for specific applications. If you're leaning towards Allen-Bradley, their systems tend to provide more robust support and scalability, which might be worth the investment in the long run, especially if reliability is crucial for your project. It might also be helpful to consider the available support and documentation for each option, as that can significantly impact your overall experience.
