At a Glance

Project comparison provides you with a concise overview of the possible differences between a project embedded in the PLC and a project in the terminal. For each project, the following information is displayed:

  • Name,

  • Version,

  • Last build: date and time the executable was last generated.

  • SourceSafeSignature: an SHA256 algorithmic fingerprint of the safe application.

Procedure

Perform the following actions to launch project comparison:

Step

Action

1

Activate the PLC > Compare command, which displays the screen below.

NOTE: Both the project and the safe application SourceSafeSignature values are compared. The combination of the two comparisons is displayed in an icon placed between the two SourceSafeSignature values:

  • The icon in the graphic, above, indicates both the Projects and the SourceSafeSignatures are DIFFERENT.

  • indicates both the Projects and the SourceSafeSignatures are EQUAL.

  • indicates the Projects are DIFFERENT, but the SourceSafeSignatures are EQUAL.

2

Confirm with OK.

Different projects

If the projects are different, 2 commands let you carry out a transfer between the terminal and the PLC or vice versa, thus changing to Equal online mode:

  • Transfer Project to PLC, transfer the project from the terminal to the PLC,

  • Transfer Project from PLC, transfer the project from the PLC to the terminal.

NOTE: When the transfer is not possible, the corresponding button is grayed out (for example, the Transfer Project from PLC command is grayed out when the project embedded in the PLC is invalid or when information required for uploading is missing or invalid).
