Hello Experts, I am writing many network Ladders for generating alarms based on some conditions, however i want to trigger alarm after some delay in case the alarm conditions are met. In the atatched program, I am using an ODT before each alarm trigger bit to turn On alarm after say 2s in case the alarm condition is met. My Question is, I have to generate 40 or more such alarms, so do I need to use seperate ODT timers before each Alarm trigerring bit? or is there any other way to avoid this. If there is, that i suppose will save processing power and time both. Please suggest accordingly! Thanks in advance! rgds, Syed AttachmentFC30_Alarm.pdf (257 Downloads) |

I tried to do that but there's no data type as timer in STAT, however instead of naming it I used a DB101 to name the SFB4 Timer and its working. Please confirm is it the correct way. Please see the attached document for my implememntation. AttachmentFB61.pdf (162 Downloads) |

Hi well ARET is right you can not use the instance DB twic inside the FB. you will have to call the SFB4 timer in STAT interface of the FB. Please attached PDF. Have fun... AttachmentOutput.pdf (188 Downloads) |

How can I reset the timer SFB5? In my attached code I want the timer SFB5 to be reset at the moment when comparator output is true. at that moment the ET value will be saved and will give me the period. Please suggest Need your expertise! AttachmentFB72.pdf (172 Downloads) |
