Hi, Here there is some tips about alarms configuration: Main steps to configure a simple alarm in HMI / WinCC Advanced: 1 –Create a tag in PLC/HMI (type integer or word) to trigger the alarm 2 – Alarm definition: for example, in the HMI tag definition, in discrete alarms. Fill alarm text 3 – Place an object to visualize the alarms (e.g. Alarm Window, in a picture). Correlation between trigger bit and address in the PLC The HMI alarm configuration refer to WORDs not BYTES (like usually organized the PLC tags). Remember: In the PLC the low byte stay on the left side of the word. For example: if configured the alarm word as MW0, will have the follow correlation Triger bit Address 0 M 1.0 1 M 1,1 ... 6 M 1.7 7 M 0.0 8 M 0.1 ... 15 M 0.7 In the FAQ http://support.automation.siemens.com/WW/view/en/41512046you chan find S7 blocks to convert bit to byte and vice versa. Sample program The attached sample program has a example of simple alarms, alarms acknowledge by PLC logic and alarms that send a acknowledge bit to the PLC.

Hi, here there is a V11 SP1 up2 verision of the project, this time with a KTP basic and a S7-1200. I think that runs in the TIA Basic... I didn't tested it yet (I ask you to give feed backs if it is ok)
