Hi, I am trying to produce basically a set of scales. Once the system is powered on and the bowl placed on top I would like to Tare the output. Here is an image of my ladder. Manually if I take the value now displayed in RealForce and enter it into ForceX1 my display goes to 0000. This is all good but now I am trying to find what I need to be able to do this by pressing a button on the screen. At present I am developing this on a USC-B10-TR22 but eventually will be transferring this to a V1210. Cheers KevB Leonardo Force Display.ulpr

Dear all, I have US5-B5-TA30 PLC with UIS-WCB2 modules and expansion adapter. I want to use PWM HSO for step control and set duty cycle, frequency and Target. In VisiLogic this was easy in HW Configuration setting High Speed Output (Step Control). In the attach you can find the example I made in VisiLogic. (LEVO - means left, DESNO - means right, on the display in the example). I am having troubles configuring the HSO on the WCB2 as PWM with target. I am relatively new to UniLogic, so please help. Thanks, BR HSO Proba - SAMBA.vlp

I'm looking for code examples to use on the UIS-WCB1_1 high speed counter. I have only found the wiring documentation for the module. And to confirm is the reset edge triggered or reset on True And there a total lack of input specifications. trial and error has me using Inp 1 for counter 1 and Inp 4 for counter 2 The info may be out there but its not jumping out at me

Hi, in my current project I have a button on my touchscreen. If this button is pressed, MB33 is set and afterwards MB 10 should be set too. But, as you can see in the image below, the execution of the net stops before MB10. Basicly I copied this structure out of this tutorial : https://www.youtube.com/watch?v=8RyFPPE3Hdk&feature=youtu.be&t=572 In the tutorial they use the same sequence of contact and coil to turn a "LED" on the touchscreen on and off. Any ideas, why it doesnt work for me?

So Im now getting my head around unistream, many thanks flex727 for the point to the examples. I have successfully got comms between uni stream and vision and have got most of my control under way and working. Took a while to get used to the new layout and working but im getting there. Question.... How do i send a set time to vision? In the vision plc there is a time entry function that communicates to other vision over modbus. I can't seem to read and write a set time both ways. uni-vis/vis-uni. Temperature settings are fine as i just use a numeric input. Just need hours and mins, is there an input for this. Many thanks, Steve

Partners, I'm having trouble moving information from one DATA TABLE to another with the same structure. The structure of my data table is as follow: Floor/number/day in/month in/year in/day out/month out/year out/hour in/time in/hour out/time out/money/quarter When a specific event happens, program calls a function that saves date and time (year in, month in, day in, hour in and minite in) in specific place of data table index A (this way I know where this event happened, becouse the first two columns on the table are the reference of the place) In table A the first to columns have constants values and never changes. When another event happen program calls another function that reads a specific row of table A and paste it on row 0 of table B adding as well the rest of the items that are mising (year out, month out, day out, hour out, minute out, money and quarter) that are calculated in this function. So table B is a registry of the events that ocurred. When I visualize TABLE B, I see all the information except the two first columns that are set as 0. I wonder if there is something Im doing wrong or if is it a specific whay of doing that. Thank you so much for your help. Marcelo

I am working on an application where I would like to show 4 indicator lights on the screen and use them to direct the operator through the process. I know how to use my MB along with SB3 to toggle another MB for on/off control , but this does not address the change in color. I also did the List of Images:Pointer and this works good for the color change, but only with the indicator always on. Is there any way to use the pointer and store direct functions for color/image, but still incorporate the SB3 when I want it to blink? Thank you, Dale

I want to configure encoder interrupt function in US5-B5-TA30 and USC-B5-TA30 My application is as follows Fault tracking system. On encoder rotation I want to shift left a array of 1600 bits. After every 250 encoder pulses I will shift by 1 , can this be possible in the above two models Encoder resolution 250 ppr . on every 250 ppr the line displacement is 250mm. max speed of line will be 45m/min. after every 250 mm I want to shift 1 bit. Total length of line is 400 meters.

EDIT BY MODERATOR: Kikis CAN NO LONGER SOURCE THIS UDFB, SO THE POST IS BEING REMOVED BUT THE LABEL RETAINED IN CASE SOMEONE IS REFERENCING IT SOMEWHERE.
-
It's rather small modification but could potentially relieve from a ton of unnecessary annoying work. Let's assume you have made UDFB which requires arguments, for later reuse gazillion times in your project. But not every time you use that UDFB, all of the input and output arguments are required. It would be nice that at least output arguments could be omitted when not necessary calling such a function. I guess that's not so hard to automatically pipe them to NULL by compiler, instead pushing us to cork every unused output with some dummy tag. Almost the same is true for inputs - assume, zero length string, zero, FALSE, for everything that's defined, but not explicitly used as input.

Trying to use a wildcard in SD Delete function (Timer1.udtf.*) . I can correctly delete the specific files(Timer1.udtf.sig) , but once I add on an * for a wild card, I get an illegal filename. How can I use a wildcard in the filename ? Thanx Allan

Hello, I'm considering what is the scope of the Positive Transition Event in the program. I thought it was supposed to stay on for one pass to the whole - but maybe that's not correct? In this example I'm catching the 100ms frequency and I'm checking it in a function which I call twice with different parameters - but the event only stays on in the first call to the function: and in this case the TestFunc is only: (N is the "Out" parameter) Is this as it is supposed to be? Thanks, Bjarni

Hi, The compiling Ladder step (when I download a program or when I connect "Online") take between 10 to 30 min . Is that normal or there is a problem with the software?

Hello Everyone, New to this software. Many thanks in advance. Question 1, So we've been able to record the data with "Data Sampling". Can someone please tell me how I can control the start and stop of data sampling? Also how may I customized the name of the sampling file, such as in MATLAB people can use the format "date is %d time is %f, DD, TT " Just so the saved data log is more readable. Question 2, How may I save a separated file content just several variables, that each time I hit a button, such as when I hit "start", save the time, date, to a txt file so I can find out when did I hit the button? Thank you very much! Yan

Hi, Is it possible to do safe remove of aUSB Stick/DOK from the ladder or a UI element? I'm saving a data row to SD, then the copying it to a DOK, all of which can be done from the ladder, using the status codes to avoid timing issues. I'd like to avoid the "DOK Unsafe Remove" warning that appears. I always get the same warning after using the safe remove button on a File Browser UI element, so this isn't a suitable workaround.

Hello all, I am using IO remote analogue card URA0400T (16 Bit) and IFM pressure transmitter 4-20mA 0-10Bar. Attached you will find the linearisation but the output value is wrong. What am I doing wrong ?

Hi there, I'm guessing that the FB that you're talking about is in Visilogic rather than Unilogic? I'm having big problems with this in unilogic. I'm trying to concatenate a bunch of strings and I just can't get anything to work reliably. Is this function synchronous or asynchronous? Any ideas why I'm having problems?

What is the most efficient way to store date and time in an excel table so that it is easily view able in Excel? I converted it to a string, but the strings take up too much PLC memory. Excel can't natively interpret Unix time, so that won't work either. Is there something else Excel can interpret that I can store it as?

Dear All, I am doing as follow: import a CSV file (copied from USB stick in the "data folder") with a single row of 23 Strings (each String is 25 lenght); create a UDTF file from this CSV; upload the UDTF to a DTI; read the DTI row. each of these action is done in a specific ladder rung; each rung check if the previously action was perfomed without problem...then at the end my CSV is converted; the DTI il filled with right values but when I read the DTI row I don't have any error (exist status "0") but the struct variables is not filled (all single field is empty)...I tried to write the DTI with the same struct and all works...the DTI take the new value...I forced the action (cvs->udtf->dti->read) then the DTI take the value of the CSV file but nothing change...the struct fields still have the previusly values. what can be wrong?

Hello, I noticed that the Unilogic software doesn't provide counters like other software's do. I am having trouble getting out of a loop pulse timer. I am trying to get out after it loops 5 times through. Any ideas?

Hi. Hope someone can help. I've got 2 analog input cards in my system. All configured the same. The one card my temp is stable but the 2nd card the reading fluctuates a lot. from 1 to 35 to 17 and so on. Connected pt100 connected to convertor to 4-20ma directly in panel to see is cable fault. Still the same. Any ideas please. Thanks.
