A good starting point for this is THIS FAQ and the referenced CPU 318 migration check tool. A 318-2 is an S7-400 packaged into an S7-300 form factor so it'll capture most program issues you can encounter. Communication calls will definitely need to be assessed separately as the S7-400 has a dedicated comms back plane for the CP's and uses different blocks. There may also be some SFC's/SFB's that require assessment and/or replacement due to the difference in backplane architecture. |
