[UniCan vulnerability]

Hello,

 

Accessing the CANBUS cable and simulating the UniCAN protocol is not an easy task but anyway thank you for bringing it up to our attention.

We will pass this suggstion along and consider it.

[CANopen, weird behavior...]

Hi Hannari,

 

According to your description it seems that the Node ID of the Mc device is somehow changes..

How do you set the Node ID of the Mc device? (Hardware dipswitches or by software)

If you change the Node ID using SDO command , note that you need to save these setting using anohter SDO command.

Usually the index for saving the settings is 0x1010 subindex 1. you will need to send the value 0x65766173

 

If this does not help please send us a mail to support@unitronics.com including the project file and the EDS and we will be happy to help!

[V120 Float: Convert]

Hi,

 

Glad to hear it is working!

OS versions V5.04 (B40) and  V5.04 (B41) had issue with this function.

[V120 Float: Convert]

Hi,

 

if what Alex suggested will not help try updating the PLC OS to the latest version and it should be fixed.

Hi Ivan,

 

You can use the Panel and the CPU Mac Address.

The Panel and CPU Mac address can be found in system tags --> CPU HW version

[Visilogic 9.7.47 and V430-TR34 PTO problem]

Hi Sasa,

 

Download & install the latest VisiLogic version 9.7.55 and this issue should be solved.

[Jazz & modbus]

Hi,

 

The answer is definitely yes.

As both Jazz and V570 can perform as MODBUS RTU master or slave and both support RS485 you can establish MODBUS communication.

Please note that for the Jazz you will have to use the add-on module JZ-RS4 (for RS485 port).

[V570 and GSM modem]

Hi,

 

According to my experience the signal quality range is from 1 to 31 (31 means best signal quality) and usually when the signal is below 11 we suggest to reposition the antenna.

18 should be good enough.

[GPRS and MODBUS ???]

Hi,

 

I was able to download and open the applicaitons without any errors.

Please try to download again (maybe the files were not downloaded completely)

In case you still face the same issue, send a mail to support@unitronics.com and we will send it to you by mail.

[Can we get a better High Speed Counter?]

Hi Greg,

 

In the latest version of UniLogic there is an option to reset the counter using a bit on the THS struct.

If you wish to set a preset value then you can review the attached application which uses a virtual counter which is based on the THS counter.

[Error with Univision Licensing & V1040]

Hi,

 

This message apears when there is a permission issue.

Please turn off the UAC and reinstall Univision Licensing.

Also try to run Univision Licensing as administrator. (right click on the Univision Licensing and choose "Run As Administrator").

[Ladder Linearize help information]

Hi Michael,

 

First of all note that if you will mouse over the parameters (A, B, C, D etc..) you will get a tooltip with the description of the specific parameter.

A - input value

B - X1  2007

C - Y1  0

D - X2 34835

E - Y2  1380

F - Result

[How do I convert a UINT32 to Real?]

Hi Greg,

 

First of all note that if you will mouse over the parameters (A, B, C, D etc..) you will get a tooltip with the description of the specific parameter.

If you wish to perform math operation between different data types, you can find in the solution explorer --> Formulas

You can prepare your own formula and combine signed integers and real numbers.

[Copy Array to a DTI column]

Hi,

 

If the structure of the data table contains the array you described then one of the columns is from type array INT x 15

Then using read row or write row you can read or write data to a specific row.

Note that you need to create another struct using the data table struct in order to link it to the read row or write row. (This struct will contain the array where you can either fill with values or get the values from the Data table).

[Move Members in a Struct]

Hi,

 

There is no option to move the members in the struct.

This request is on our list and hopefully in the future will be available.

[Support for UDP_RAW socket]

Hi,

 

It is not in our immediate plans, but it is a strong possibility for the future.

[Data table communication]

Hi,

 

Currently there is no direct way to access the data tables memory.

You can built your own protocol to read write data to data tables. You can create commands and messages with variables using message composer in UniLogic and then using TCP TX and TCP RX ladder elements you send and receive data. 

 

For example you can send the string Read_Row1 from your PC applicaiton and then when the UniStream recieves this message, it will activate read row for the requested index number and for specific tags and then will send the data back to the PC application.

[Advanced web server graphs and Arduino help]

Hi,

 

You can create a link to a file which is on the SD card. Then you can either download or open the file.

In the advacned webserver example there is a link to download PDF file and UDT file. 

[How to upload the ladder program together with all "MI memory" from Unitronic V280]

Hi,

 

Using VisiLogic connection menu, you have the option "Export operands to File". You have the option also later to import the file back to the PLC.

Another option is using Remote Access under tools menu you can select operand access and import or export operands to Excel.

Hi Denis,

 

In hardware configuration --> properties of the analog channel, you can already set the min/max values of the analog channel based on the scaling limits.

[JAZZ & program protection...]

Hi,

 

Using UniDownload Designer you can prepare a UDC file (Downloader file) that the customer will be able only to open using UniDownloader software tool and download the applicaiton without the option to view the source code.

First you will need to prepare *.d90 file. (when download the application to a controller, select advanced in the download form and check the option "create download file")

Then in U90Ladder --> Tools, select UniDownload designer and prepare the UDC file.

Ask the customer to download UniDownloader from Unitronics website and send him the UDC file.

After the customer will install UniDownloader, he will need only to double click on the UDC file and download it to the controller.

[UniLogics]

Hi,

 

Yes you are right, you will need to use the linearization included in the math toolbox in ladder and then show the result value on the HMI.

[prablems with uploading]

Hi.

 

Please send a mail to support@unitronics.com and we will check this issue deeply.

[Hooking up to 14 devices in modbus]

Hi,

In the future we will add the option to copy slave and have HMI variable that the user will be able to enter the slave ID/IP.

Currently for each slave you configure in UniLogic, in its properties you can find a parameter "Active" - you can link a bit to this parameter and then you can disable/enable a specific slave.

You can also set "Active" bit for each one of the MODBUS commands.
