 To read carefully before integration of a M580 Safety PAC.

                                        WARNING
UNEXPECTED BEHAVIOR OF THE APPLICATION
To program your functional safety applications,
 
  • use Control Expert V14.0 + ControlExpert_V140_HF1 + ControlExpert_V140_HF2
  • or use a version of Control Expert greater than V14.0.
Failure to follow these instructions can result in death, serious injury, or equipment damage

In Control Expert V14.0, the initial values of parameters or internal variables of function blocks (EFB or DFB) used in M580 Safety controllers
(in a safety or a non-safety program section) can be lost in the following use cases :
 
  • Open a STA file, do a “Rebuild all project”.
  • Open a STA file, do modifications inside a DFB and do a “Build Changes”.
  • Upload an application from a M580 Safety controller, do a “Rebuild all project”.
  • Upload an application from a M580 Safety controller and do modifications inside a DFB and do a “Build Changes”.
After these use cases the application is incorrect.

This issue is fixed in ControlExpert_V140_HF2 and in Control Expert versions greater than V14.0.
