Alexia posted a topic in Other PLCsHi I need to show 2 different history buffer setup ID's in a single Historical Trend graph. as much as I tried only 1 ID of buffer setup is shown on trend graphs, but for comparison purposes I need to show 2 or even more? ( i already have defined 2 rows of my history buffer setup with different D in row 1 and 2 = ID1 and ID2 ) can somebody help me please? thanks
I current have 2 variable: Displacement vs Pressure. I need to draw a real time graph on Comfort Panel. The problem with using just f(x) trend is that the minimum time between updating a point is 0.5 sec and that is for ever in my application as the whole cycle last only 5 sec and I have to plot 500 points in that time. Is there a way to do real time graph using Historical data without any time delay. If anybody can guide me through any sample program or material would e helpful. Thanks
Hi all, I'm using S7 graph and I would like to be able to jump to a step after a warm restart of the PLC. This is to be able to carry on from the step the sequence was in before the restart. I have figured out that I can select a step in Manual mode. So if during the warm restart I pulse a bit for the input to SW_MAN then Load an INT value representing the S_NO before the restart into S_SEL and then pulse another bit into SW_AUTO. Will the sequencer carry on like normal in auto mode from the selected step?
Hi im quite new to Siemens programing. I got a issue that iwe been stuck with for a while now when im programing in Graph. When a supervision_fault happens the sequence is locked until I press ACK_EF and the transition is fullfilled. Then the sequence continues right on. What I want is that if ACK_EF is pressed the supervision fault will be cleared and the sequence remains paused until I press "Startbutton" again. I´ve tried Halt_SQ when the FAULT is triggered but I cant seem to get the FAULT down when I ACK. Also tried to switching it over to manual then ACK the fault. But that didnt work for me either. Hope there is someone that could help me with this :) It would be much appreciated!
