Device | PLC that uses programmable logic. Devices referenced in this document are PLC processors and HMI handheld pendant. |
Program | AKA code, application, source code The control logic, memory and parameters running in a Device. |
Master | The running code in the Device that you make changes. Software definition for published software is that the Master is the controlled source code from which all copies are made. It is the program we start with when making changes. PLC prototype world (the one we live in) is different from other software environments. We have, and will only ever have, one installation of each program. It is our running code. There is one instance. It exists on the Target Device. |
Controlled Copy | For PLC programs: The Controlled Program uploaded and saved in the appropriate git folder. It is our preferred Backup. For HMI program: The source code that was downloaded into the HMI and saved in the appropriate git folder. It is our preferred Backup. |
Uncontrolled Copy | All other copies of the program. These are usually For Reference Only. |
Working Copy | Any copy of the program that has been modified while not online with the Device. Working copies should be uniquely named to avoid misidentification as a Controlled Copy or git-copy Uncontrolled Copy. |
git folder | The folder containing the Controlled Copy. It is created on your computer during installation of git. Do not save working programs in git. |
git_copy folder | The DropBox folder for uncontrolled copies that have been directly uploaded from the Device. This folder is available for use by anyone. It is not required to use this folder. It is a history of the running code on the date saved. This is useful when the Controlled Copy is not updated during the course of a code change. Do not modify programs in git_copy. Do not save working programs in git-copy. |
upload | Transfer a program from the http://Device.device to the editor. |
download | Transfer a program from the editor to the Device |
Verify | Confirm that the code change is according to the specification. |
Validate | Confirm that the code change operates according to the specification. |
