  1. Dear all i have a problem in HMI it gives an error of stop mode plc how can i reset it or jump to run mode
  2. Is there a way to re-order regions? in the ladder?
  3. i am create application with messages for audit traill actions the operation. I wold like select the message with index , show in left collun. But not found way for select message for write in table dti or external ( sql table). I need help for optimize application and not repeat many times same code. i hope developer team create one way for create selection more easy. regards,
  4. I've tried to find a way to load a HMI screen via ladder within UniStream (which I found to be a very useful function within VisiLogic), but so far without success. Is there a way to get things done like: if a condition turns on screen n° xxx will be opened? Thanks for your feedback. Olaf
  5. Hi, In my UniLogic project I have some binary text objects associated with digital input bits. I expect that the text inside the text object changes accordingly to the associated bit, in this case the state of the digital input pin then. Going online to debug the program I am forcing the input state of the digital input pins and nothing happens, the text in binary text object does not change. If I apply a voltage to the digital input, so that it reads 1, the binary text changes as expected. If in a rung I insert a contact associated to the digital input bit that drives a coil associated to a memory bit variable, then if in HMI I associate the binary text object to that bit variable, I can see it changing if in online mode I force the state of the digital input. Does anyone know a fix to this annoying bug? If the PLC is not nearby it's a pain to debug and I'd like to avoid to mirror all the digital inputs on bit variables just to fix this. Thanks.
  6. Hello Gents and Ladies, I am new to the unistream line. Haven't had chance to take the seminar for it. It definitely little bit different then Visilogic line as for programming. Just trying to figure the math out. Some of it turning out to be zero. Just can't figure out what I am doing wrong. If you care for some points. Would like to see math examples. Thanks PICC1.ulpr
  7. Hello there, i'm trying to find a way to Initialize the TCP/IP card with the IP,Mask,default Getaway from the data that i initially put in the device through the Information mode. I found the Retry and Timeout Registers (SI 101,102) but i can't find the IP, Mask and default getaway to Dynamically Initialize the TC/IP card. I don't want to have different .vlp's for each device. P.S. i also saw the MI option but it would put unnecessary complexity to the ladder program (need to have two modes in start up etc.). thanks in advance, Nassos
  8. Hello, Is there any way to implement timers in UDFB?
  9. The majority of my current applications involve Load Cells. I currently use V350 and/or V560 with an EX-A2X expansion adapter to an LC1/LC3. I originally used EX-RC1 but deviated from it and use exclusively EX-A2X because I can email and explain to any customer how to upload clones for any specialized changes I make to the V350 and V560. Since you need to be physically plugged into the EX-RC1 to do any upgrades its usefulness has its limits. So My question is what is the easiest way to utilize load cells if we do make the jump to Unistream line of PLCs? I'm really hoping my options are not limited to CanBus to EX-RC1. At least it is an option, but I would likely add more Analog I/O to the same location, which goes back to making changes a bit more difficult. I know there are other ways to upload a program to the EX-RC1 but Internet connection is not readily available at all machine locations, and having a guy on the other end of the phone with any amount of programming knowledge never happens, so the less I need to walk someone through how to use a computer the better. Plus the machinery moves and most plants don't want to take the time to plug the system into their router, let alone properly set up a network.
  10. In helping a customer integrate a UniStream into a SCADA system I have come across a curious gap in the available information. I can't see any declaration of the function codes that the external Modbus master must use to communicate with the UniStream as a slave. The Unitronics example and tutorials use a UniStream as the master as well as the slave, which doesn't highlight this issue. I have looked within UniLogic, tried exporting the Modbus registers as excel, looked at the UniLogic help file, watched the Unitronics YouTube video and searched the forum. None of these sources gave the necessary information So far I have gleaned that the following codes are supported on a UniStream modbus slave: Coils Read Coils (function code 1) Write Coils (function code 5) Write Multiple Coils (function code 15) Registers/Words Read Holding Registers (function code 3) Write Single Register (function code 6) Write Multiple Registers (function code 16) But what if the customer's master only supports Read Input Registers (function code 4)? I don't have a firm answer on how we could handle this. Can anyone provide a definitive list? I would like to be able to answer this question with confidence. A standard part of documenting a Modbus Slave is to specify which function codes it supports, so the master can be correctly programmed. Thanks, Simon
  11. Hi people! I'm developing a project with UniLogic v1.25.61 for the UniStream USP-104-B10. I need to sort an entire Data Table (2 columns, A and B), sorting just one column (A), has anyone ever try this? The other option is to have 2 arrays (A and B), sort one (A) of them and then I need to sort the other one (B) the same way I sorted the first one (A). I don't know if I'm being clear enough so here you have an example: Before sorting: A={1,4,2,3} B={Q,W,E,R} After sorting just column A or array A: A={1,2,3,4} B={Q,E,R,W} Thanks in advance! Cheers, Gonzalo
  12. Hello All, Can someone help to build a simple program for switching multiple outputs with delay ? Condition is: Input ON, Output 1 ON then delay XX seconds Output 2 ON, and .... delay XX seconds Output X ON. Input OFF, Output 1 OFF then delay XX seconds Output 2 OFF, and .... delay XX seconds Output X OFF. thanks in advance.
  13. Hello all, this is the first time I am writing to this forum. We were using vision plcs and now is the first time we are using unistream. We have connected the cards through USP-TCP. For the analogue input we are using the card URA-0800O and we set the input 4-20mA. The sensor we are using is 4-20mA 0-150oC. We tried linearization but the output value is wrong. In X1 we entered the value 818 and X2=4092. in Y1 we entered the value 0 and Y2=1500 but the output value is 0 and does not change. When we change the Axis values (y1=818,y2=4092,x1=0,x2=1500) in linearization, shows an output value but is 10-15 degrees less than the actual temperature. Are we doing something wrong? Thanks
  14. Is it possible to make the substring or remove string length variable? I need to read a string with changing amount o characters. I need to read from / to the next / for example.
  15. Hi, In my program PID auto tune is not functioning. Overshoot came across when I tried it. After that I entered values manually in the PID loop.In that also little bit of overshoot could observed. May I get some help from to solve the PID issue.
  16. Hi All, I'm storing data in a Data Table. Once a day I write the data to a file using the "Store DTI to File" instruction. It all works well and a file is created. I'm then using Excel VBA to read the data in one line at a time. The issue I am having is that the CSV file has comma "," separating the lines. How do I get the Unitronics software to install a line break after each row from the data table?
  17. Hello, I'm new at Automation Programming and i would like to know how to simulate an Analogic Input in Unilogic, in-time modification to test levels etc. Is it possible ?
  18. Hi guys. I try use local integer variable in UDFB with inc block, but not work. I know not possible monitoring a value on line, but i connect in function out in the block and not change values outside . The inc function not work in blocks with local variables? Regards
  19. Hello, I am a new programmer in Unilogics. After I got to know Unilogics , I have to set up an TCP/IP connection. The PLC is the server. I already programmed a function for sending information to the Hercules ( on my laptop). Now I need to receive information back from my Hercules. I have tried a lot of options but it will not work. The Rx blocks count the right amount of byte's that is received. The problem lays ( I think) in the fact that OUT E from the Rx box doesn't go to 1. Also I dont get BOX E from de parse message box. If i made a scanned message for receiving it isn't standing there. I find it very strange that i find it so easily to send info but then it wont work to receive info. thank you for the help in advance NOTE: " BUFFER ONTVANGEN MEANS BUFFER RECEIVED" im dutch haha
  20. Dear Sir, Please help on following DTI usage. I am using EXCEL sheet as attached for showing volume of tank. We have 2 conditions. 1. NEGATIVE TRIM 2. POSITIVE TRIM. trim is calculated by our sensor. The height of the liquid is also calculated by pressure sensor. From the liquid height according to positive or negative trim, select the volume from the cell. This value want show in a numeric box. For example, I know my tank list is positive and sounding is 0.25 and trim of 1.5, as per excel sheet my volume will be 5.12 Metric cube. Want to pick this 5.12 value and show in numeric box. if in negative trim, at 0.25 depth and negative trim of 1 my volume will be -0.67 metric cube. From excel sheet how I can select using DTI I marked it red for ease of reading. Can you help on this please. I have limited access to internet. cannot search and study the examples. This will be great help for me. With regards Attachments area NO1TSWBP.xls
  21. Dear sir/Madam, I done small projects with UniStream. I got one large project. Can i have some help to carry out this project. I am not so professional oly a small scale programmer. I'm attaching one of screen shots of an existing project. we are planning to upgrade this with Unistream PLC. In the photo red color valves, when we touch on particular valve a pop up screen should come with showing two buttons OPEN CLOSE. like at right side upper corner of the screen. can we do this by designing single screen and when touch the valve the screen will pop for with that particular valve number. or we have to make pop screen for each valve. like this there are 3 screens with same number of valves. I did not buy the HMI UNIT and CPU to try. Please help.
  22. Hi. How can i change a data table fields using c function? Can you please send me an example?
  23. Hi! I'm programming an UniStream Modular USP-070-B08 + CPU USC-P-B10 with UniLogic v1.25.61. I want to create an array of INT16, which its length, will be set by the user through the HMI. Is it possible? Because when I create the array in Ladder, I can only set a constant value for the array's length. I want to try something similar with the number of rows for a table. Thanks in advance!
  24. I have used the UniStream in 2 applications and I am a fan. I would like to know if you can edit your ladder and do a download while the PLC is still running.
  25. I need to calculate the difference between the current tag value and its value during the previous scan. The tag value originates from a Formula using analogue data from a UIA-0402N Analog input and stores a Real value. Is there a easy way to do this without using a Data Table or other FB that uses the SD card memory?
