How to create a trend - from a database-table in Citect Scada (v7.40)
rajsiyer posted a topic in HMI & SCADA
Hi friends, The scene is like this... I have some 200 energy meters whose readings are continuously logged at 15-min intervals into a logging table. The meter does not have any other value logged. Let's consider these readings as analog tags. However these tag values are continuously increasing to ever larger numbers. Thus we have a problem for display on trends. Customer now requires that the Citect shows usage trends for any meter for a specified period of the past. That is to say, the meter that he wishes to observe is selected - along with a period typically between 2 dates (perhaps also with a sampling period) - and the trend must appear. So in other words, given a single trend object, how do you make values appear for any selected tag on this trend. Perhaps this can be overcome by some genie/super-genie mechanism. My approach to this is...For the selected meter, I use SQL to query the 15 minute logged values (also taking into account the required sampling period) taking the reading on starting date as initial. All values thereafter are subtracted -within the SQL query- and the result of this query is kept in a 2 dimensional array(x for time, Y for value) or a new database table so that the trend displays values starting with zero. This much I can do with Cicode. After this, I need a method to display the values so obtained in a trend object. Essentially this is the same as feeding a trend object with a set of X & Y values that I have in the form of an array or in a database table. I shall greatly appreciate any help to meet the above objective. Thanks for looking in. With best wishes. -
The Sysmac Trend Graph can only load 8 analog traces at a time. I am needing to create a screen that will allow me to select the variables I want to show on the Trend Graph. It looks like I can only hard code the data points I want into the Trend Graph Properties window. Is there a way (possibly using vb) that I can programmatically load the traces I want into the Trend? Any help would be much appreciated.

Hello.I'm having variable Voltage expressed as UNSIGNED DOUBLE INT.For example: Val = 23423For displaying the right value I have to divide value by 100 ... Val/100 = 234.23V.For showing the value I can set the decimal place to 2 and Unit&Scale to 1002.The problem is:THE GRAPH IS SHOWING Val=23423. I WOULD LIKE TO SHOW Val=234.23.HOW CAN I USE THE DECIMAL PLACES IN GRAPH?WHERE CAN I SET THIS SETTING?Thanks.BR, Andrej.

How to show 2 different data history in a single Historical trend graph in DOPSOFT-Delta HMI?
Alexia posted a topic in Other PLCs
Hi 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 -
Hi Guys! I have an another question , I hope you guys can/want to help me. I have some problem with an proface panel. I want to make a hisotrical trend, but when I want to select the channels (tags what I want to monitor) I can't select anything, because undetermined. I think I should set the tags kind of a buffer list, but I don't find it. So my question is how can I set the tags. I can't changed it at all. If the answer is I need to make a buffer list, then where can I find it ? Thank you so much.

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

Hello, Does anyone know if there is a method or function that can be used to define the Trend start date? I would like my trend to automatically default to 12:00am on opening, or at the least, have a button to return the start date to 12:00 of the current day. or have a userinput section that they can use to select the date and time to display. This is for logging and printing purposes. Thanks!

I’m having some trouble trying to save test data to a trend file. It's a E1151 HMI connected to an FX3U PLC (with 2 ADC's, and 1 DAC). I can get it all to work for a few lines but then it just stops, for no apparent reason. Has anyone else run in to this problem before? I have attached the trend setup, it starts to collect data but then just stops 5 lines in, half way though outputting the time, without an “End” statement or anything. It looks like it’s crashed or run out of memory, but I’m fairly sure there should be enough memory to store this. Example trend file. 28.09.16,16:09:40,0,34,6.8,0.200951,-0.00421429,0.0605635,7.53491,123456789 28.09.16,16:11:05,0,0,0,0,0,0,0,0 28.09.16,16:11:10,17227,0,6.8,0,0,0,0,0 28.09.16,16:11:20,17227,35,6.8,0,0,0,0,0 28.09.16,16:11:36,17227,35,6.8,0,0,0,0,223456789 28.09.16,16 Another example after I changed the sample count to 65534 29.09.16,11:47:23,0,0,0,0,0,0,0,0 29.09.16,11:53:33,17227,35,6.8,0.156296,-0.00648355,0.060258,7.53232,0 29.09.16,12:10:30,17227,35,6.8,0.156296,-0.00648355,0.060258,7.53232,0,OFF 29.09.16,12:11:07,17227,35,6.8,0.156296,-0.00648355,0.060258,7.53232,0 2

in Citect i use the following function to associate various Tags with the next popup window, in the previous versions the tags passed to the trend fine since upgrading to 7.4 the trend pens dont display but all the values display fine. FUNCTION // function AssPIDPopup // Expand a full set of PID tags and open // the PID block supergenie AssPIDPopUp(STRING sSGenie,STRING sBasePIDTag) AssVarTags(-2,0,sBasePIDTag + "_PV"); AssVarTags(-2,1,sBasePIDTag + "_SP"); AssVarTags(-2,2,sBasePIDTag + "_OP"); AssVarTags(-2,3,sBasePIDTag + "_MAN"); // Now the tags for the PID tuning SG AssVarTags(-2,4,sBasePIDTag + "_KP"); AssVarTags(-2,5,sBasePIDTag + "_KI"); AssVarTags(-2,6,sBasePIDTag + "_KD"); AssPopUp(sSGenie); END I added a button to run the following code FUNCTION Loadtrend() TrnSetPen(19, 1, AssInfoEx(1,0)); TrnSetPen(19, 2, AssInfoEx(2,0)); TrnSetPen(19, 3, AssInfoEx(3,0)); Prompt("Test"); END when clicked the pens set to the trend fine, i tried to run the code from a function but it did not work. i am new to citect and am sure i am missing something stupid.

FactoryTalk View ME Trend Fails to show Datalog Data when using Parameters
enfermot posted a topic in Allen Bradley / Rockwell Automation
I believe I have found a bug in FactoryTalk View ME version 8.10. I have a trend object that uses parameter file placeholders on the connections tab. These are direct-addressed to the shortcut ie {[PLC]...}. The historical data from the datalog does not show. (The pens write lines, but when I navigate away from the screen and come back, the lines are gone and begin drawing again from the right side.) The current data does show. This tells me that the placeholders are correct syntax. When the screen loads, the placeholders are being replaced by a string which yields a correct tag path, or else the pens would not be writing correct data. When I replace the placeholders manually and directly address the tag, the historical data does show correctly. This tells me that the datalog is set up correctly and is logging data. I have verified that a previous project of mine, using I believe version 6.0, successfully used this method of using one screen and one trend to plot various tags using parameter placeholders, and the historical data did show correctly. -
Hi all, I have built trend for a pressure transducer. It is working fine when the trend is open. However, When I go to different pages and come back to the trend, It loses all the data it was showing before. The HMI is panelview plus 700. What is this path?? Can anyone help me with this Any help would be great. Thanks

Greetings, everyone! I come back here seeking for help. Here is my (detailed) issue: > I have a simple INT variable tag, let's call it temperature (with Eng Zero and Full Scale defined). > Afterwards, I defined the trend tag temp, with the following options: - type: TRN_PERIODIC; - storage method: Scaled (2-byte samples); - sample period: 0.500. > I used the Trend Tool, and inserted the trend in my graphic page and (in the Trend Properties) I assigned one of the pens with the trend tag temp. After doing all of these, and after compiling and running the project, nothing is shown in the trend graph. I must mention that I can modify the value of temperature analogically in the graphic page using some buttons. My OS is Windows 7 Ultimate, 64 bit. Can anyone please help me with this issue? I really must know if my way of doing things is not in order. Looking forward to anyone's reply.

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!
