I am looking for some help with displaying multiple messages for a plant alarm system that I am creating. I have attached for info. I have also added a log file to record all the plant alarms (hopefully I did that correctly). The amber screen indicates a remote plant alarm to where the logo will be located to make it visually obvious. All alarms show perfectly, I am using a High signal with priority 0 to show the default message screen. I am not up to speed with FBD as I have hardly ever used it and it is a learning curve compared to ladder. My problem is if two or more inputs are on at the same time, I want to have the logo scroll between the active alarms until they are cleared. I saw a file using shift registers to display multiple messages however I couldn't work out how to make it check for more than one input on at a time. Any help would be much appreciated. I hope you understand what I am hoping to achieve. AttachmentPlant alarm singles.zip (358 Downloads) |

The log is not so function. When the input of data logs with 1 signal is activated, only one entry is created. always remains the input goes high, is no longer logged. For each event that is logged, you must drive the input of the data logs with positive edges. must have at least a break of 500 ms between the edges.

Hi, I don't believe it work as you want because in LOGO! there is no Alarming like in HMI's. Here is maybe somthing you can use. If case of an alarm the message will be shown and the background is flashing. In case of an second alarm additionally Next is displayed to indicate there is more than a single alarm.
