At the beginning of any controls migration project is the debate over minimizing field wiring changes versus the advantages of all new/different cabling. Since each project is different, there isn’t a “best way” for all projects. This post provides examples of control system upgrades that re-use existing field wiring.
The first video describes a changeover in the late 1990’s from a Honeywell TDC2000 system to a Foxboro I/A system. In this design, the old Honeywell Basic Controller card-cage/backplanes were used to house the new Foxboro cards. This video was included because several current projects involve the replacement of the Foxboro I/A equipment, and many control engineers aren’t aware that this Foxboro-in-a-Honeywell-backplane design exists.
The next group of videos are listed by migration type:
Honeywell TDC 2000/3000 system to an Emerson Delta V system.
Bailey to Emerson Delta V migration.
Bailey to Rockwell ControlLogix migration.
PLC5 to ControlLogix migration.
