Hi all I have some trouble making this work correctly. I'm using a these controls (modified) - analog input in this case: https://support.automation.siemens.com/WW/llisapi.dll?func=cslib.csinfo&objId=31624179&nodeid4=20229806&load=content&lang=en&siteid=cseus&aktprim=4&objaction=csview&extranet=standard&viewreg=WW This is what i would like to have: 1. Each limit (4 pcs.total)has its own alarm(4 pcs) or warning(4 pcs) messages. 2. All alarm/warnings use the same ack. bit. 3. If I ack. ie. High Alarm then my symbol remains red, but if HighHigh Alarm then occur, then the symbol would blink again. 4. I can ack. alarms from the faceplate or from the alarm control (group ack.) The problem right now is at no. 4 - I can make this work when I use the button on the faceplate but I cannot get the alarm control to set my ack. bit. I use the same bit on the buttonas in the alarmlogging (a bit in the HMI command word). When I use the button, then the alarms in the alarm list is also acknowledged, but when i ack. from the alarmlist, then the alarms is ack. in the alarmlist, but the bit in the plc is not set, so the symbol is not showing the correct status. (not using alarm status in the alarm logging - would this help?) (if I make each message - "a single acknowledged only" - then the bit is set) I have used "Group messages", where I have added these 4 alarm messages/4 warning messages and added this ack. bit. What have I missed? Thx |
