  1. I had the same problem, stopping the sampler, and in the next cycle of the program I start the sampler. This doesn't work. I have to let the PLC doing another run 1 cycle and then I can restart the sampler... maybe a status bit would be nice to say that file is being saved, so we can use this bit for restarting the sampler...
  2. I want to store a specific string (read fixed) to a "string tag" according a value. If value = 1, then string should be "OK" - value = 2, string is "NOT OK", value = 3, string is "FAULT...",.... OK, I know I can do this with the compare instructions, but I want to do this with the switch case instruction....😎 suggestions anybody ?
  3. I have a project with a USP-104-B10 and several URB remote I/O modules connected. When I add an IN or OUT module on the USP-104-B10 and then I export the IOtags to Excel, then the modules are not ordened anymore... the last added IO module is putted at the end of the excel file...even this is the first module of the project isn't it possible to export the IO/tags in order they are on the PLC ?
  4. I use Sick RFU610-10600 rfid reader, connected via TCP Sick provides a EDS file, so very easy to configure ! no programming needed..... just add a node in ethernet/ip scanner and that's it...
  5. Hi, I rewrote my program, so I divided the large rungs into more rungs. But still I have a question and problem. Is it possible that the PLC reads a bad value from the datatables while the data tables are updated with " remote access " ? Every cycle I read the data table, but the customer changed the values of the data table and suddenly he had wrong values ? I checked the program, but couldn't find any wrong programming.
  6. Hi, When I change the data table in the instruction "read row from data tables", the destination operands are dissappearing. This gives me a lot of work extra. We do not have this "problem" with te "read column....) maybe something for a next version of visilogic ?
  7. Ok, thanks first, I will replace the "bad" program with the "correct" one and test it. If there are still problems, I will send you a copy of the program so you can check where the problem can be. I'll keep you informed about my results.
  8. Ok, I think this will be the problem ( bad programming of me ! ) But 1 question about this issue : is the order of commands execution always the same, or can it change in time. The most of the time, I get "good" values, but suddenly I get a wrong one ! Or is the time needed for an read data table column and put the values into the MI's taking some time, so this is sometimes slower and I get "bad" result. this is because I want to explain my customer why the PLC sometimes gives the "wrong" values.
  9. I have the following problem : In net 1, I read a column of a data table in MI100 ... MI 109 in the same net (net 1) I search a certain value in the MI100...MI109, with a CALL subroutine that returns a returnvalue. Is this allowed, or should I search this value in another net ? Because sometimes (not always) I don't have the correct returnvalue ? program look likes this : read column and write to MI 100...MI 109 // search value into MI 1 // call subroutine for searching where MI 1 is in MI 100...MI 109 // put return value into MI 2 ( all this is place in one net ! )
  10. I've made a project where the user has the abbility of changing his "receipts" in the data tables. I have 10 different receipts (so 10 different data tables the user can modify), but when i am executing the receipt, I copy the values of the asked receipt into a new data table (called the working data table). The problem is that the user also can modify the "working data table" and this is not wanted. Is there a possibility to set or unset the viewing of certain data tables (customer uses the remote access software to change the receipts) is there a way to reorder the data tables ( now t
  11. When downloading a project to a V570, with the option to syncronize the time between PC and PLC the UniDownloader (ver 5.0.07) will fail to do ! first it will syncornise the time, but the PLC stops running and the only way to "run" the PLC is via the sofware visilogic. I'm not able to restart the PLC with the Debug screen. The only way the downloader works is to upgrade only the application (did not tried to download the bin,boot and OS) all software (on PC and PLC) are the latest version
  12. started this topic one year ago, but still no app to download ? I found something in the app store for Ipad customers : the software HMI draw from sweetwilliamsl.com -> price 0.99 $ of 0.89 € I bougth this, tested it and approved 100 % good. But you have still a lot af programming to do !
  13. I have a customer who wants to use excel to download and read the MI's from the PLC. This you can do with UNIDDE, but we can only read/write the memory of the PLC. Is there an easy way to read/write the data from the data table's via UNIDDE ?
  14. I'm very pleased that the idea of creating an "app" - (for Ios and Android) of "remote access" will be considered. I can not wait until they appear in the app store !
  15. now we need an win based PC to run remote operator of remote access. When You make this work on a android based of apple based (ipad?) system, then we have a very powerfull system, because we only need to program the PLC and not some difficult HTML pages ! An yes, I want to control the PLC from Tampa to Sofia. The amount of users ? I think 1 at a time is enough, because you are using the screens of the PLC (like you are in front of the PLC)
