  1. Hi, Local structure lost/corrupt data outside of subroutine . When you require to save data to SD, Ladder leave routine and cannot pass right data to SD driver. This is how local variables are working. Use Global structure. Than it will work. B.R.
  2. Hi, I can add to what other peoples recommend. - Check if you connect connectorfirmly. - Some peoples by mistake connect down side (output) 0V and +V to up connector instead of down connector. In some cases peoples spent days to find this. B.R.
  3. Hi, Please visit Unitronics Helpdesk https://support.unitronics.com/index.php and search for BacNet. You can find 2 articles, for Vision and for UniStream B.R.
  4. If you mean CT is a Current Transformer, then output is current, not voltage. For current input you have to configure analog input in hardware configuration as current, and use I input. For voltage input you have to configure analog input in hardware configuration as voltage, and use V input. B.R.
  5. Please check if your CT device is compatible with UIA-0800N module. And if you configured right UIA-0800N current loop channel. You have to use linearization to convert current loop input to engineering value. B.R.
  6. It is OK. But why do you use 6 wires cable MJ20-CB200 to connect modem to PLC? Use 4 wires cable (cross-crimped). ! Phone cable may be straight, but you need cross-crimped one ! It is from RS232-CB1 set (MJ10-22-CS25 DB9 to 6p6c adapter + 4 wires cross-crimped flat phone cable). B.R.
  7. Hi Paul, Default baud rate for V350 RS232 communication is 115200 bps. This is why PLC lost communication during system files upgrade. B.R.
  8. Hi Philip, Please send your request to support@unitronics.com B.R.
  9. Hi, I can add to what DanT say. Use the same VisiLogic you used to download project to PLC last time. This is important to have all system files compatible with used VisiLogic version. Only OS may be updated from SD card.
  10. AjaS, There may be number of conditions leading to problems with SD/Disk on key mount and read at PC and UniStream PLC. *This example processed with 8 GB SD card and SD to USB adapter *If you have important files at SD/Disk on key - make backup. 1. If use Virtual Machine. Please check that selected USB port is linked to this VM 2. Open DOS prompt (Administrative) at VM. 3. Run "diskpart" 4. Enter "list disk". This command will list disks at your Windows VM. DISKPART> list disk Disk ### Status Size Free Dyn Gpt -------- ------------- ------- ------- --- --- Disk 0 Online 465 GB 0 B Disk 1 Online 931 GB 0 B For example, you have 2 disks, as listed. 5. Insert your SD/Disk on key to linked to this VM USB or SD slot. 6. Enter "list disk". This command will list disks at your Windows VM. DISKPART> list disk Disk ### Status Size Free Dyn Gpt -------- ------------- ------- ------- --- --- Disk 0 Online 465 GB 0 B Disk 1 Online 931 GB 0 B * Disk 2 Online 7580 MB 0 B New disk should be listed. If new disk is not listed, than there is a problem you should solve by IT. 7. Suppose that a new disk listed. Enter "select disk 2". 8. Enter "list partition" DISKPART> list partition Partition ### Type Size Offset ------------- ---------------- ------- ------- * Partition 1 Primary 7580 MB 0 B Offset should not be 0 B 9. Enter "clean" DISKPART> clean This will clean partition information from selected disk. TAKE CARE TO SELECT new listed disk. EVERYTHING will be deleted from selected disk. This will take some time to prosess. Be patient. 10. When finished, message will be displayed: DISKPART> clean DiskPart succeeded in cleaning the disk. 11. Enter "list disk". DISKPART> list disk Disk ### Status Size Free Dyn Gpt -------- ------------- ------- ------- --- --- Disk 0 Online 465 GB 0 B Disk 1 Online 931 GB 0 B * Disk 2 Online 7580 MB 0 B New disk should be listed and marked by *. 12. Suppose that a new disk listed. Enter "select disk 2". 13. Enter "list partition" DISKPART> list partition There are no partitions on this disk to show. 14. Enter "create partition primary" DISKPART> create partition primary DiskPart succeeded in creating the specified partition. 15. Enter "list partition" DISKPART> list partition Partition ### Type Size Offset ------------- ---------------- ------- ------- * Partition 1 Primary 7579 MB 1024 KB Offset should not be 0 B 16. Enter "detail partition" DISKPART> detail partition Partition 1 Type : 06 Hidden: No Active: No Offset in Bytes: 1048576 Volume ### Ltr Label Fs Type Size Status Info ---------- --- ----------- ----- ---------- ------- --------- -------- * Volume 4 E RAW Removable 7579 MB Healthy File system is RAW (not formatted) 17. Format new disk from VM Windows File Explorer with cluster size 4096. 18. Enter "detail partition" DISKPART> detail partition Partition 1 Type : 0B Hidden: No Active: No Offset in Bytes: 1048576 Volume ### Ltr Label Fs Type Size Status Info ---------- --- ----------- ----- ---------- ------- --------- -------- * Volume 4 E FAT32 Removable 7579 MB Healthy File system is FAT32 19. Enter "exit"to close diskpart. DISKPART> exit Leaving DiskPart... C:\> 20. You can close DOD prompt. 21. Eject SD/Disk on key from OS and detach it from PC USB port. 22. Insert SD/Disk on key to SAD slot or to USB connector at PLC. 23. Go to UniApps at PLC. 24. Select Memory->File Browser. 25. For SD card you can see list of default directories. 26. For Dosk on key DOK you can see list of files or directories, if presented. Hope this helps to make SD/Disk on key working. B.R.
  11. Hi AjaS, There is a lot of time pass since last post. Can you explain your problem with more details? - SD/Disk on key size. - Number of partitions. - Partitions format. - UniLogic version you use. - Windows version you use. - Does IT department limit PC access to only for sertified by IP SD/Disk on key? - Sequence of operations you doing. - At what step and what error appear?
  12. See following Forum topic:
  13. If used V570 include Mini-USB port - you can use USB to Mini-USB standard cable. *You have to install USB driver before you use USB connection. Do it from Connection->Communication & OS->right-most tab. Click "Install USB Driver" than "Open Device Manager" to find COM Port number to use in VisiLogic. Then connect mini-USB cable to PLC and to PC. Or you can use USB-to-Serial converter P/N MJ10-22-CS35, and RS232-CB1 set, supplied by Unitronics and distributors. *USB-to-Serial converter P/N MJ10-22-CS35 include all required RS232 lines. It use Prolific chip. RS232-CB1 set include MJ10-22-CS25 DB9 to phone 6p6c socket adapter and cross-crimped 4 wires phone cable. Then you can communicate to PPLC. Hope this information helps. B.R.
  14. Hi chand345, Please provide TC connection diagram and snapshot of module configuration. This will help to better understand your setup. B.R.
