  1. Hi I have a question about ladder programming (in visilogic): MI1 is coming from a keypad entry, the value range is 0-100. MI2 is coming from an analog input, and is already scaled to the range 0-100. How can i force MI1 to #0 if MI2<20. The MI1 should not be changable by the keypad when MI2<20. Sorry for such a easy and maby silly question. -- IanM
  2. When I put operand(which has a operand description) on the screen in the ladder, then I cannot see operand description. If it is the description short, it is shown, but only when it is MB operand. I have 9.3.1 version of Visilogic on Windows 7. I have tried advices (changing resolution, size of fonts etc..) which were mentioned in the other topic but they has not worked. College has the same version, same resolotion of the screen, same OS and it works correctly but He did not remember if He changed some settings. Could you help me?
  3. Hello, I've noticed that when I create a UDFB it feels like I'm not getting enough control of it. For example in one of my UDFB's I'd like to be able to enter eighter string or an int value in one input, but you can only have one type. If I make two inputs with different types, I have to put something on both or it won't work (compilation error) Is there a way to fix this? Or is this some feature that is going to be added in the future? Thanks, Exouxas
  4. G'day! I'm having some issues retrieving info from a specific row in a table, is there an easy way to do this? I've tried using "Read Row from DTI", but it asks me to use a struct as an output with the same row structure, but I want this rows output to go into a single variable. Thanks, Exouxas
  5. Hi, In a previews version of UniLogic I was able to export a function NOT being a UDFB and pick it up in an other project which worked well. Now I am using v 1.7.62 and trying to export a function gets stuck in a pop-up menu telling me that UniLogic is preparing memory location.(there is more than enough space ). Canceling is no option because UniLogic does not react to that. the only way out is to terminate UniLogic. I have now upgraded to v 1.8.51 and it does exactly the same thing. Is this a problem in my computer? can someone test this on his/her computer? Thanks, Derk
  6. How can I convert the a number to string? For example I would like the number 126 to be converted to the string "126".
  7. Hi all, I've started using a UniStream product (USP-070-B10) having previously used a Vision V1210 and was wondering if there was a similar thing to the SB2 contact for the UniStream PLCs / UniLogic. I used SB2 in ladder previously to do things that that needed to be done at startup, and only once, like initializing values, etc. I’d like to do something similar now, but to load up data tables, to make sure that they are present in memory before using them (as look-up tables for data/calculations). This would ensure that the data’s there in the tables if a power outage occurs, etc. Any ideas for how to do this?
  8. What is the relationship to ladder programs and regions in a module? Is there a main ladder program that runs and I need to call all the rest including regions separately? Do all the Ladder programs in every module run without any calls? Do I need to call the main ladder function something special so that UniLogic knows to run it first?
  9. I need to convert a number that is expressed as an ASCII String to a UINT32 value. The only FB I can find that appears to be intended for this purpose is the STRING to NUM function but I cannot find any examples or references to this block in the Help File. The FB appears to be looking for the ASCII Operand (A) and then outputs the "Resulting Number" (, and the "Factor" ©. I take it that B is where the Integer Value should output and I cannot figure out what C is other than possibly a multiplication factor? When I upload my program to the PLC and go online, My ASCII String Value (A) shows up fine but the FB will not output anything other than a "1" for the value and a "0" as the "Factor". I tried to override the output values to be sure they were actually being written to and I cannot change them. Can anybody give me some direction on this? A simple example file would be ideal. Joe
  10. Hi, #1 - The UniLogic help files refer to linearization for numeric box. Where is that functionality? #2 - Does the linearize under math functions follow the same format as VisiLogic? I could use more explanation of the tag values associated with it.
  11. I have a problem with the local tags in my UDFB. They don't change their state. For example, when I try to set a coil that has a local tag, the local tag's value remains unchanged (zero). I am using the latest version of unilogic. What can I be doing wrong? Thanks in advance.
  12. I 'm trying to use this Ladder Function to copy one array (of integers) to another. As I understand it, parameters A and B specifiy the source array and offset, parameters D and E specify the target array and offset, and parameter C specifies the length (no of items) to be copied. I would have expected parameter C to be an integer, but the compiler is demanding an array! Have I misunderstood the function? Robin Proctor
  13. Hi, I defined a Tag named: Dd, from type UINT16[0...7] I putted there: Dd[0] - System RTC Time Seconds. Dd[1] - System RTC Time Minutes. ... Dd[7] - System RTC Date Day of Week. In "Store in Array" I can only set all Dd, not different elements of Dd. Obviously I can use Ladder Element Store for every one but it is silly. Is there a more elegant solution?
  14. Hi! I've made a Function that calculates flow to quantity a day. I want to use this as a UDFB several times, for all of my flowmeters (30), but only the first of them gives an output-value?? Can't a UDFB only be used more than once?
  15. Hi all, I've been spending almost one day looking how I could compare to ASCII strings without success unfortunately. The idea is to compare a string from the HMI (username) with a String inside a user account data table loaded into a struct row after row. This is just to be able to make a kind of login function with user and password protection. Guillaume
  16. Hi all! We have string data types available now, and a whole category of ladder stuff for searching and manipulating them,never the less, I cannot find any way to display a string on the HMI (analog to the ASCII String variable in VisiLogic). Where is this hide? Is there a way to invoke a variable within a fixed (or other) text object?
  17. This is a UDFB for linear ramp output with rise and fall time. The program detects change in the target value and ramps the output until it reaches the set point. If the new target value is greater than the current value, it makes a rising ramp. If the new target value is less than the current value, it makes a falling ramp. Calculates the relative ramp time according to maximum ramp and fall time given by the user. Function Inputs: Target value Rise time (This is the maximum rise time from the minimum output value to the maximum in msec) Fall time (This is the maximum fall time from the Maximum output value to the Minimum in msec) Maximum value of output Minimum value of output Function Output: Ramped output register Application: I wrote this UDFB to control hydraulic pressure using proportional valve via analog output. It could also be used to drive a stepper motor with acc/dec using pulse width modulation.
  18. Hello, Have I posibility to take out the project from Jazz PLC and import it in PC to analize how it was the ladder created if the project wasn't protected with password? Thank You and sorry for my bad english.
