Upgrade Examples

 
In other page links, you can read of specific upgrade examples. Here is a list of control system upgrades we have completed with mention of the old controller, the new controller/PLC, the client, and then number of systems updated.

Old controller                       New PLC             Client           # updated

Microprocessor system     Direct Logic         Praxair          many dozens

Microprocessor system     Do-more              Headway        seven

WinPLC                             Do-more              Priefert           seventeen, all unique

Think & Do PC                  Productivity         MCAAP           three

Acromix WinPLC               Do-more              multiple          eleven to date, in seven states

AB SLC500                        BRX                    SMG               six

Microprocessor system     CompactLogix     TI                   two w/ 33 scheduled

Microprocessor system     CompactLogix     TSMC            fifty nine

Microprocessor system     BRX                     IBM                twenty six to date

Direct Logic                       BRX                     CAT                two

Direct Logic                       BRX                     SA Recycling one

CompactLogix                   Do-more              Maples Rugs one, 8 remote bases

Siemens                            Do-more              HDT                two

Multiple AB PLCs              BRX                    Sheridan, WY  many

WinPLC                             Do-more             Yellowstone NP still counting

For those showing WinPLC as the old controller, all were updated with a change in the PLC CPU (Do-more) and often a new HMI. All other updates required a full replacement of the PLC, I/O cards, and HMI with necessary re-wiring.
