  1. Hi, I did check for number of Project Examples back, and all of them use port 123. Where did you found port number 555???
  2. DanT, Do you have EDS file for module? Import it and if there are no errors - required structures will be created.
  3. Hi all, I will tell my short story about registry editing: I did Registry edit at big Network Management System (not for the first time), but this time I failed into big problem - Microsoft Server being just "bricked". - The bad - "bricked" Server. - The good - I remember at what hive I did edit, and there were number of similar Network Management Systems at lab. So I did copy of the same hive from one of working Network Management Systems to this one, used one of available at Internet tools to boot computer from CD and import hive I killed. Required number of reboots to fix some things - and my salary bonus stay with me. Lets suppose what happens if only one computer exists with this configuration. So Registry editing is so simple... And you should decide if you do it or not. Happy Registry editing!
  4. There is 4A fuse inside. So if your power supply has load capacity less than 4A, than short time reverse polarity may activate power supply short circuit protection. It is recommended to be careful with power supply polarity.
  5. Bstip, 1. What model of USB-to-Serial converter do you use? Do you have other model of USB-to-Serial converter? or example FTDI based chip. Try it. 2. About commu8nication speed - recommended to keep it 115200 (default). It is recommended to use PLC COM 1 serial port and check that it is configured as RS232 115200, 8, N, 1. *Start PLC when pressing I button to start in STOP mode with default RS232 settings 115200, 8, N, 1. If PLC has touch disp[lay - power PLC when touching display. When down counter appears, release and then double-touch display to start in STOP mode with default RS232 settings 115200, 8, N, 1. Repeat download. 3. Use "Stop-Download-Reset" mode to download project.
  6. Please forward your request to support@unitronics.com Forum cannot resolve this.
  7. Hello all, When you asking for help, please always state U90Ladder/VisiLogic/UniLogic etc. version. Do not write "last version". Knowing exact version will make our help fastest. Anyway, first installation should be processed with Administrator rights (assist your IT), then replace file. Replacement will require Administrator rights as well. Then you will continue your work without Administrator rights. Knowing your version we will send you link to download proper file. B.R.
  8. Please forward your request to support@unitronics.com
  9. Please send such requests to support@unitronics.com with explanation of project potential and other details. B.R.
  10. Khom, You have to set Timeout to 10 sec. Then check again. Does communication works?
  11. We do not recommend to work with projects, located at mapped drives, or flash drives of any type. We recommend to copy project to local drive, work with it, than save changed/edited copy back to your archive with a new version number. In case of USB interface problem, or network problem, you can finish with lost projects.
  12. UniStream supporting only selected modems from modems list. In your case you have to use "Protocol" to send and parse messages to/from your modem. You can download UniLogic examples from following link: https://www.unitronicsplc.com/software-unilogic-for-programmable-controllers/ https://www.unitronicsplc.com/Download/SoftwareVersions/UniLogic/UniLogic_Examples.zip Unzip and review examples in directory: E:\Unitronics Software\UniLogic\UniLogic_Example_Projects_1.30.58\UniLogic Examples_V1.30 Rev 52\Communications\Protocol\UniStream_070_Message_Composer_Example.ulpr and other.
  13. Jpalas, This forum is for Unitronics PLCs. If you are working with Schneider PLC only - we cannot help. If you should interface from Schneider PLC to Unitronics PLC, then better explain what you should do on Unitronics PLC and what communication protocol you use to communicate between Schneider PLC and Unitronics PLC, and what Unitronics PLC model supposed to use. B.R.
  14. You can find original Helpdesk article at next link: Prepare Disk on Key (DOK) or SD card to work with PLC https://support.unitronics.com/index.php?/selfhelp/view-article/prepare-disk-on-key-dok-or-sd-card-to-work-with-plc
  15. Tested and approved: When battery is discharged to some predefined level, than engine does not stop at red traffic light. Even if battery is charged - very slow motion prevent engine stop. For me engine stop is very annoying, especially at short traffic light, when my car is not first, and other cars has similar behavior. So it will take 2-3 times more to pass junction with a short traffic light.
  16. It is possible to use Action from Ladder -> "Take Screenshot": You can find last screenshot name in next system tag: The system saves the current HMI screen as a graphic image in jpeg format. The image is saved, with a time stamp, on the controller's SD card in :\\Media\PrintScreens.
  17. SM35-J-RA22 has 37 ohm resistor at current input. Applying 24V dissipate ~16W at small resistor. Unitronics already made precautions in Installation Guide: Looks like there are 2 groups of peoples: 1. Read and then do. 2. Do, then read, than say "wow/heh...".
  18. You can find all information at Internet (Google or other search engine). It is recommended to use RS485 interface instead of RS232 interface.
  19. Hi, I am not sure about compatibility of schneider lv434000 and Siemens PLCs in addressing of memory. May be review of next link may help you: https://www.unitronicsplc.com/support-tools-and-applications/
  20. 1. After loading timer value to ML, divide ML by 100 and it will be in seconds. 2. The fact that linearization accepting big values (ML or MI) does not mean that you should use big values. There are multiplication and division inside linearization FB and in some cases result may surprise you. 2.1. You always should test worst case. 2.2. In case of not accepted results you have to optimize used numbers. B.R.
  21. This problem is "invented". Vision timer has format: HH:MM:SS.mm -> 5:00:00.00 Not X1=1800000 (timer value 5:00:00:00 loaded on ML) Minimum timer interval for timer is 10 mSec. For 5 hours interval you do not need precision of 10 mSec. So value in ML for 5 hours (in seconds) should be 18000. Hope that precision of 1 sec will be more than enough for your linearization. Even 1 minute step will be good. In this case linearization should work. If not - use formula from Help.
