Network Controller Upgrade
Some systems (including the product lines that my company reps) allow for a “partial upgrade”, meaning that you can leave most (if not all) of your controllers in place (at least for the time being), and simply replace your main network controller with the latest and greatest, typically utilizing a gateway to communicate with the existing “old school” controllers. So what does this get you?

Like everything else, the BAS has a useful lifespan. It’s easy to compare the need for an upgrade in computer terms, stating that, as technology changes, the old stuff becomes obsolete, and the new stuff becomes the state-of-the-art. As with a personal computer, your BAS will eventually reach obsolescence, and while the life span of your system may well be two to even three times that of your typical pc, you still need to know when it’s time to start considering the path to total system upgrade. A phased upgrade, as discussed herein, may be an option, and could very much be your best plan. Just be mindful of the obstacles involved, and make sure you understand in no vague concepts what you’re up against and what to expect during the upgrade, and after all is said and done.
Tip of the Month: Don’t wait ‘til it’s too late! Get your control systems service provider in to evaluate your existing system and furnish a quotation for upgrade recommendations, and work it into your budget. Worst case, if you wait until your system finally does fail, you’ll already have the paperwork in hand and it’s just a matter of making a phone call to put the upgrade work in motion!
