Appendix D – System Evaluation Tool Survey Questionnaire
Introduction
This questionnaire is meant to help those who want to evaluate an OSx/PCS or Tistar
system for migration to PCS 7/505 OS. Migration means that the customer replaces his
OSx/PCS or Tistar system with a PCS 7/505 OS system communicating with the same
PLCs. The supervisory logic and strategy used in the OSx/PCS or Tistar system is
replicated (as much as possible) on the PCS 7/505 OS system. That will involve moving
some data and configurations from the old system to the new system.
Because PCS 7/505 and OSx/PCS/Tistar do not have the same exact architecture and
features, you must evaluate the OSx/PCS/Tistar
system so that a decision can be made on
whether a conversion project is worth the effort and what level of effort is involved. The
alternative is to replace the OSx/PCS/Tistar system with a new PCS 7 system whose
configurations and graphics have been created from scratch.
Customers have much invested in the existing hardware and in the intellectual property
(IP) that is represented by their control strategy. They are eager to preserve as much of it
as possible. However, all systems eventually reach their end of life and for computerized
systems, this could be much sooner than the end of life of the process being controlled.
This questionnaire can help make the decision of how much hardware and IP can be
preserved during the conversion.
A companion software tool exists that can be run on the system to be evaluated. It will
help obtain that data that is difficult, tedious, or time consuming to obtain manually.
