[BACnet - BACnet slave and modbus config file]

Hi,

Please visit Unitronics Helpdesk

and search for BacNet.

You can find 2 articles, for Vision and for UniStream

[Reading analog inputs]

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.

 

[Reading analog inputs]

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.

[Can't initialize COM2 port on vision 1210]

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).

[Visilogic V9.8.80 Failure on V350]

Hi Paul,

Default baud rate for V350 RS232 communication is 115200 bps.

This is why PLC lost communication during system files upgrade.

[Communication Driver Error (206)]

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.

 

[Unistream don't acknowledge the DOK (USB)]

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

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

File system is FAT32

19. Enter "exit"to close diskpart.

DISKPART> exit

Leaving DiskPart...

C:\>

20. You can close DOS 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.

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?

See following Forum topic:

 

[V570 to PC]

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.

["List of Texts: by pointer" but for numerical values]

Hi Ken,

List of Text use MI as a string index.

You can store respective values in sequential MIs and use indirect  store MI to copy corresponding to string index MI to other MI, which you can show on display.

Hope this is what you requested.

About image quality:

Display resolution is 320x240 dots. *PLC is not smartphone.

Image allocate part of display. So it's size is smallest.

You do not need to use highest resolution images. It is useless.

[Read Single-precision arrays with Modbus TCP/IP]

Hi,

I used next link:

https://www.h-schmidt.net/FloatConverter/IEEE754.html

Result is 0x3e18a71e, as you have.

Now you have to swap  0x3e18a71e to 0xa71e3e18 and use  "Vector->Use Offset->Copy Memory" to copy ML/DW to MF.

Than MF should show right number.

Update us if it is working for you.

Thank you for update.

Well done!

Hi,

What exactly you did?

What do you store to MF?

With more detailed explanation help may be more detailed.

[Read Single-precision arrays with Modbus TCP/IP]

Hi Charalambos,

Please publish here content of 2 sequential MIs you read from meter in HEX and tell us what number it should show.

*Read it from meter display, if possible.

Having this information it is simple to negotiate if pairs of Bytes should be swapped or Bytes should be arranged in some order.

[V350 with multiple slaves frozes Modbus RTU Port]

Hi,

It is recommended to use not so long timeout and set Retry counter to 0.

If device is disconnected, time delay to set "No Communication"status is TIMEOUT*4 (one transmit and 3 retries by default).

In case you set timeout to 10 sec, delay to communicate to next device is 10*4=40.

PLC will be pooled one time and Master PLC will communicate to next PLC.

Best Regards.
