DoctorsCreek Posted December 14, 2017 Report Share Posted December 14, 2017 Hello. I am a new user of a Samba 4.3. I recently bought a brewing system and it came pre-loaded with a brewing program on a Samba SM43-J-TA22. I am interested in learning Visilogic and writing a simple program to control a water solenoid by temperature for my fermenter. Can the Samba operate two distinct programs at different times? Example: I power it up and have an option of what program I want to operate. Or, do I need to add to the existing program? I am in no rush to get this completed as I want to take my time and slowly learn the basics of Visilogic. Thanks! Quote Link to comment Share on other sites More sharing options...
MVP 2021 Flex727 Posted December 14, 2017 MVP 2021 Report Share Posted December 14, 2017 If you have the original .vlp file, then you can create anything you want and have a bit to run your new subroutines to the exclusion of the original subroutines and vice versa. Other than that there is no capability to load two totally separate programs into the PLC at the same time. Quote Link to comment Share on other sites More sharing options...
DoctorsCreek Posted December 15, 2017 Author Report Share Posted December 15, 2017 Thank you for the response. Is there a way to extract the .vlp file from the Samba, or is just an executable file that the Samba is running? Thanks again. I appreciate the help.

MVP 2021 Flex727 Posted December 15, 2017 MVP 2021 Report Share Posted December 15, 2017 If the "Burn Upload Project" option was selected when the project was downloaded, then the .vlp file can be extracted. If not, then no. Once you download a new project, the previous project in the PLC is gone forever. Quote Link to comment Share on other sites More sharing options...
