[V350 using GSM modem and ethernet card]

Hello, I use the Unitronics V350-35-T38, where port 1 is RS232 and port 2 is the ethernet card. When I had setup GSM modem on the port 1 and I had tried to download the program to the PLC I had got a message that I had to change the firmware (OS) in the PLC to the version which support ProfiBus and dial function. So I did that, but then the ethernet card was unavaible. I need both - GSM modem and ethernet card. I tried this in the latest version of Visilogic. Then I tried 9.6 version of Visilogic because in the past we used both and we used this version. I do not know why now it is not possible. Could you help me? Thank you in advance.

[Using DT in C function]

Hello,

 

I don't believe you can address the data table directly in the C function.  You would have to perform a 'read row from DTI' to put the row information into a tag.  Then pass this tag (which will be a struct) into your C function.

 

It is important to note that when passing the struct into a subroutine, the struct will update with each scan since it is a passed in by reference.  You will not have to pass the struct back out - it will be updated as it moves through the subroutine.

 

Hope this helps.

Thank you, but it is possible to use directly DT, but in last version of Unistream you can choose type of input DT then in C code is automatically generated this structure:

typedef struct

{

  unsigned int BufferPointer; // BufferPointer

  unsigned int EntrySize; // EntrySize

  unsigned int Number_of_rows; // Number of rows

  unsigned int Signature; // Signature

  char Status; // Status

  char PadUInt[3]; // PadUInt

} Data_Table_Indexed; // Data Table: Indexed

but I do not know what to do with these members of the structure( I know C programming very well and I can work with structures etc.) . I mean how to get data from that. I tried to read from all, I tried to write one of them then read from the others etc...,  but I have got just garbage values...

Hello,
I'm trying to read values from a data table within a C function. I cannot find any examples.

Could you show some examples?

[An array as output of a function]

I need to write to INT16 array in C function. Is it possible to do it? I have noticed the header of a C function contains only inputs. I tried to directly write to an array(which was the input of a function) but it did not work.

[How it is the easist way to display data table]

I have a datable which contains 400 rows. I need to display 20 rows. Now I am doing it manually but I think it is not a good way. I tried to do it with C function and UDFB but they do not support more than 10 outputs. Has the Unilogic a function to do reading from a data table in the loop and is it possible to read data table within C function? How to do it the easist way?

Thank you in advance.

[Changing a parameter in a number of HMI widgets]

How can I change the same parameter when I have marked more than 1 element? For example I would like to change decimal point location at 3 numeric boxs on the same location. Is it possible or I have to do it one by one?

Thank you in advance.

[Operand description is not shown in the ladder]

Hi,

1. Please send screenshots of this issue.

2. Please send the details of your system - CPU type, operating system, system memory etc.

3. Anyway, we recommend updating your Visilogic version. The current version is 9.7.9, and has a lot of fixes in it.

 

Here are the details of my system:

Win7 Professional, Service pack 1, 64bit

8GB RAM

Intel Core i7 4510U

 

You mentioned updating Visilogic, I am not sure that I can because we use Uni350-35-r34 and we have older firmware in ( and we have o lot these PLC so it is not possible to update all of them). And second reason is all my company use version 9.3.1 when I create project in 9.7.9 version will they abble to open it?

[Operand description is not shown in the ladder]

When I put operand(which has a operand description) on the screen in the ladder, then I cannot see operand description. If it is the description short, it is shown, but only when it is MB operand. I have 9.3.1 version of Visilogic on Windows 7. I have tried advices (changing resolution, size of fonts etc..) which were mentioned in the other topic but they has not worked. College has the same version, same resolotion of the screen, same OS and it works correctly but He did not remember if He changed some settings. Could you help me?

[Adjustable shift register]

Thanks, but I need to create an oscillator. If I do not use the timer coil it will not oscillate.. I need to increment the counter in defined time(which can be changed via HMI). Is there any other easy way to do it?

[Adjustable shift register]

Thanks. I have done my "project". But I have 1 problem with  toggling an outputs which I have been solving for 1 week but I still can not find the solution. I can not use your solution because I use the timer which time settings value is from variable in HMI. It is not a constant in the program. Why does my oscillator count twice faster?

In the Visilogic menu look at Help->Examples

Thanks, but I can not find any similar examples.

My first problem was resolved. Now I am thinking how to switch outputs periodically..

[Adjustable shift register]

Hello I am beginner of Unitronics PLC. I have V350 series,R34. Is here a demo or an example this type of application? First problem which I have to solve is how to set value into timer by writing value via HMI. Could you help me?
