Hello,

I use cpu IM151-8 and KP400.

During startup some alarm message already appear on the screen, while the alarms are not there.

To prevent this, I would like to use an init-bit from the KP400 to know when the KP400 is completely started, before the blocks in OB1 are called.

Is there an init-bit in the KP400?

Hello jf.fortuin

you could probably use the Area pointer "Coordination".

You can use the Area Pointer in your Connection to the PLC.

Then you can see Informatoin about the Panel in the The Area pointer in the PLC.

you have the bits:

- Startup Bit

- Operation Mode

- Life bit

Further Information you can find in the TIA Portal Informatoin System.

Good luck

Bye Murof
