Loading and Starting the Standard Function

The IP 265 must be set to POWER OFF when the submodule is being inserted.
• Switch off the programmable controller
• Slide the submodule into the receptacle until it engages. Then switch the programmable
controller on again.
The IP 265 now loads the PLC program from the submodule. The IP 265 indicates that loading is in
progress by flashing the STOP LED on the frontplate of the module.Loading is completed after
approximately 3 seconds.
The STOP LED now remains lit.
Status of the IP 265 after loading from the submodule
After the submodule program has been loaded, the IP 265 is in the STOP state.
Execute the following steps to start the IP 265:
• If the CPU is at STOP, switch it to RUN.
• Now switch the IP 265 to RUN also via the IP 265 control word.
Note
The RUN bit must always be set during counting.
Communication between the CPU and the IP 265 is not possible with RUN = "0".
If the CPU goes to STOP, the IP 265 also goes to STOP. The counter function is then not
processed. After a renewed STOP RUN transition, the counter function must be reset.
