Automation, automation, automation.  Now that the economy is just beginning to recover, most manufacturing companies report that they are planning to invest in more and more automation. 

For more than 30 years we have been using our trusty PLC’s because they are simple and reliable, if a bit quirky.  PLC’s have practically merged with PC’s in recent times. 

Then the PLC sprouted wings and emerged as a PAC.  If you’re not already familiar with a PAC – that’s a Programmable Automation Controller.  These units combine the sturdy reliability of the PLC with the programming language of a PC.

Did you know that many modern control systems are now being designed for a minimum 30-year lifespan?  Hmmm. 

Many early systems are still going strong that were installed in the ’90s, ’80s and even some from the 1970s.  But you probably already knew that since so many of you send us your controllers for repairs.

The weaker links in these older systems are the operator terminals, disk drives, power supplies, keyboards, and CRT’s as they often have mechanical or electrical parts that simply wear out.  Many of these units can be repaired and if not, replaced with refurbs or updated, drop-in replacements.
