  1. What DataXport version are you using? The most latest is V3.1.16 and I recommend downloading it from here. If updating DataXport doesn't solve the issue, please contact me at support@unitronics.com
  2. Hi Ronald, Open the ULP file in DataXport, go to "Project" menu and select the option "Log Files". Now select one or more logs and press "Remove".
  3. The USB host in Unistream had been tested with several devices. All tested devices were using the Prolific PL2303 family drivers. If possible, please send me the specifications of the Prolific controller PL2303HXD you mentioned.
  4. Hi Robin, There are two main download types in Unilogic - with and without reset. Most users prefer the download without reset option - mainly because it doesn't involve stopping the process when making changes to controller on site. If you want to go to the main screen after download, either use the "Download and Reset" feature or alternatively create a "Home Page" button for each display.
  5. Regarding adding a swapped bytes feature - I will add a request to our features list. Regarding conditions for swapping - there are several approaches for such condition. I would use the following: Storing the original tag (lets name it A) to another 2 tags (lets name them B and C) Swapping the bytes in B Running a continuous compare function between the A and C - when A is different then C that means that another value was stored to the PLC and another swapping is necessary.
  6. Hi Kjensen, To understand what exactly isn't working in the application, I will need you to post the application itself for inspection.
  7. Hi Michal, If you are getting wrong values for the R.F.R command, there is a good chance that your device sends a swapped message (the bytes order is reversed). In that case, you can use the Swap Single Tag Bytes ladder function block found in the Logic tab. change the swap type to ABCD_CDAB. Please let me know if that solved the problem.
  8. Hi Ran, In general, OS update does not affect the resident application whatsoever. In some models (especially V350), some older function blocks were replaced, but that doesn't apply for the V130. Also, the current Visilogic version stands on V9.7.44. It is recommended to update both the application and OS to the most recent version.
  9. Hi akodmon, Currently, there is no support for IP cameras in Unistream. In the new upcoming version of Unilogic, IP cameras working with RTSP (Real Time Streaming Protocol) will be supported by Unistream. Supported video format is MPEG-4 Visual, part 2, AVC/H.264.
  10. Hi Flex, You can keep the Vision IO modules and switch to Unistream in one condition - you need to use EX-RC1 as a bridge between the Unistream and the Vision IO's. I attached an example that shows how to use EX-RC1 with Unistream. EX-RC1_IO.rar
  11. Hi Rene, Please see the attached project. In the Data Sampler1 struct there is a "Create CSV" bit. When this bit is turned on, every time you will stop the sampling or when the sampler reaches the maximum samples (60000 samples) a new CSV will be written to the SD card. Please let me know if that works for you. UniStream_070_Data_Sampling_And_Trend.ulpr
  12. Hi Marius, Please see the attached image. There is a Timer/Counter HMI variable that presents timer values. you can present and/or edit both preset and current timer values.
  13. Hi Marius, You can easily create a blinking led by using SB3 as your contact. SB3 is a 1 sec pulse generator.
  14. Hi Ivan, Unfortunately, you cannot configure the USB ports (or install drivers) on the Unistream to support specific devices. To communicate with a device over RS-232 layer, you should either use a USB to serial adapter (available also from Unitronics), or install one of the Unistream serial communication modules.
  15. Hi Allen, Currently, Unitronics supports 3g modem networking only for the Unistream series (using this modem). However, supporting 3g modems for the Vision series is one of our highest priorities, and it is expected in several months time.
  16. You set a bit to send the modbus command but didn't reset it after the command had been executed (see image).
  17. The permission denied error may point to bad dll registration issues. Please try to reinstall Visilogic with administrator privileges. To do that right click on the installation file, select properties and press the Unblock button. Then run the file as administrator. From the installation menu select Repair. Please let me know if that solved the problem
  18. Hi, For customized products requests, please write to export@unitronics.com
  19. Hi, Please check the following: 1. Check if the Sim Card is inserted correctly to the modem. 2. Is the sim card protected with a pin code? 3. Is the Sim card open for data communication (contact you cellular provider). 4. In Modem services, enter your cell phone number in the "Number to Dial" box. Then press "SMS Options". From the SMS Options window, enter some text in the "Send Message" box, and press "Send SMS message". you should receive the message in your cell phone. If you cannot receive the message, or getting a modem error message, please let me know.
  20. Hi, As you probably know, ASCII is protocol for characters representation. Every character is stored in one byte of data. In visilogic, ASCII strings are stored to MI's, hence two characters in a single MI. For a full date to be represented, you need to store 9 characters (8 for the actual date + NULL character), which translates to 5 MI's. This information also appears on the format selection in the RTC to ASCII function block. So, in your application the date should be stored in MI150-154, and the time should be stored in MI155-159 (or anywhere you like).
  21. Hi, SI274-276 count any type of serial message received in the PLC (including Protocol messages) after it has been validated. These counters values are being reset in PLC start up.
  22. Hi darknesspic, You have several methods for storing data in non-volatile memory when using Vision PLC's. As long as the battery in the PLC is functioning properly, the data will be stored even after power loss. The two most common will be: 1. Simply store the value to either MI,ML,DW or MF operands. 2. Work with data tables - create you own data structures and store/retrieve them when necessary. You can find much more information in Visilogic Help.
  23. Hi Burnout2676, The Unitronics Vision series is an integrated PLC and HMI solution in a single unit. It was designed to work with Unitronics IDE (Visilogic) and consists of an internal operating system. This operating system is upgrade-able, and Unitronics frequently releases these updates. However, it is not possible to replace this OS with an external one (i.e Linux or Windows).
  24. Hi LPK, As for all PLC's the input channels are being sampled once per scan (at the beginning of the cycle). The smoothing feature does not change the system's behavior in any way. all it does is presenting an average value of the input. Consequently, the update frequency for these values will vary according to the smoothing selection.
