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)

TESTED BUT FAILED
Pegaia, Thank you for the effort. I am however having trouble to open the project correctly. First my version was not right.. I did not have UPDATE 2 loaded. So I did that first. Now I get a very strange error message - the system requesting WinCC SP1 Update2. According to the install version status window this is what is installed. See the JPG for details. I notice however that you have used a TP1200 Comfort as panel and not the Basic Panel. Again refer to the JPG. I think the problem is that TIA BASIC does not handle the TP1200 Comfort. Why the error message does not just say I require TIA Professional, is an open question. [wink+smile] Maybe I should get a sponsor for buying me TIA Professional.. I seem to be the only one with TIA Basic wanting to see inside this program. Hope this feedback helps. |

Hello Simon N, What do you use acknowledge about PLC or acknowledge about HMI? You can see more information for alarms in the following manual. See chapter 9.3.2 Working with alarms. WinCC Comfort / WinCC Advanced V11.0 SP1 Tweety |
