How to migrate a Safety application for Modicon M580 / EcoStrucxure Control Expert with a Safe Peer to Peer communication from ECE<15.0 to ECE>=15.0 and a CPU FW >= 3.20

Issue

• Modicon M580 Safety with EcoStrucxure Control Expert V15 implements a new safety time management principle no more based on NTP services.
• New peer to peer communication EFB are provided to replace legacy ones.
• Compiling an earlier application containing legacy EFBs will lead to compilation errors.

Environment

• ECE>=15.0 and CPU FW >= 3.20

Resolution
here is the list of steps to go through :

• Set the application level to 3.20
• Suppress in the logic each instance of S_SYST_CLOCK_MX
• Replace in the logic each instance of the S_RD_ETH_MX FB with the S_RD_ETH_MX2 FB.
• Replace in the logic each instance of the S_WR_ETH_MX FB with the S_WR_ETH_MX2 FB.
• Create and connect the CONTROL_DATA to each of the S_RD_ ETH_MX2 / S_WR_ ETH_MX2 FB
• Add the communication transfer of the CONTROL_DATA from Receiver PAC to Sender PAC
• Do you want to delete all unused SAFE variables?
  • yes
    • Purge all unused variables in the Safety Data Editor, in the Function Blocks folder
    • Purge unused Type in the Derived FB Types Editor
  • no
    • Delete manually all S_RD_ETH_MX & S_WR_ETH_MX variables, in the Function Blocks folder
    • Delete manually all S_RD_ETH_MX & S_WR_ETH_MX FB types, in the Derived FB Types Editor
• Purge unused Types in the Types Library Manager  – in the <Application> view of the types

FAQ Applicable Conditions (Optional)
Both CPU linked via peer to peer must be version SV3.20 or later
