116 CoDeSys 2.3 Runtime Environment WAGO-I/O-SYSTEM 750758-874/000-131 WAGO-I/O-IPC-C6ManualVersion 1.0.011.6.7 Creating a Boot ProjectSo that the PLC program automatically restarts after restarting the I/O-IPC, createa boot project. To do this, select Online > Create boot project in the menu bar.Make sure that you are still logged in to CoDeSys.Boot project automatically loadIn addition, you can load the boot project automatically when starting the I/O-IPC. Click on the "Resources" tab and open the "Target settings". Select the"General" tab and then "Load boot project automatically".If a boot project (DEFAULT.PRG and DEFAULT.CHK) is present under/home/codesys and the "Run/Stop" switch of the I/O-IPC is set at "Run", the I/O-IPC automatically starts with the processing of the PLC program. If the switch isset at "Stop", the PLC program is not started.If a PLC program is running in the I/O-IPC, a PLC task starts with the reading ofthe fieldbus data (only for I/O-IPC with fieldbus connections), the integrated inputand output data and the internal data buses. The output data changed in the PLCprogram is updated after the PLC task is processed. A change in operating mode("Stop/Run") is only carried out at the end of a PLC task. The cycle time includesthe time from the start of the PLC program to the next start. If a larger loop isprogrammed within a PLC program, the PLC task time is prolonged accordingly.The inputs and outputs are updated during processing. These updates only takeplace at the end of a PLC task.
