"In the absence of pushbuttons on the LCP, we had to carry a handheld version of the TWC transmistter out to a particular inductive loop in order to enter a request. Considering the inconvenience of having to walk out to the yard with the handheld, we decided to add real control capability to the panel." I don't doubt this is the case, but I don't understand why suppliers do things like this. Seems like it ruins the good will between the supplier and the customer.
Galen, you seem to have found a good solution to your problem. The only question I have in these instances is that of certification. Is there an issue with that when field modifications are made to the control system?
At the Design News webinar on June 27, learn all about aluminum extrusion: designing the right shape so it costs the least, is simplest to manufacture, and best fits the application's structural requirements.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This radio show will show what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
