[Tension Control]

Hi Ron,

I assume you are using some type of 0-10v or 4-20mA to Pressure regulator to control the brake? PID control is the norm. You will probably end up leaving the D gain 0. You'll want to come up with some sort of scheme to adjust the response as the diameter winds down.

Hi Damian,

Thanks for the reply.

Yes I will be using a 4 - 20mA to regulate the powder clutch brake. i am not worried about the diameter as i am using a loadcell to check the actual tension in the web. this in turn modifies the brake condition.

[Ascii Strings]

Hi,

I have tried UniDDE to exchange numeric values between an Excel Sheet & a Vision 130. Can UniDDE be used to exchange Ascii Strings? If yes, then how.

Thanks

Ron

[Tension Control]

Hi,

I have to control the tension in a Web. We will be using a V130 + LC1 along with a Load cell. What would be the right way to go about this. Should I use a PID to control the the brake on the unwinder? Or is there another way of doing it. I will be using LC1 for the first time.

Thanks,

Ron

[TEST Bit Function]

Hi,

As per your HELP Section on TEST Bit, if I need to test bit no. 10 of ML2, then I need to enter a value of 10 in the Offset of the function. However, I find that in order to test bit no. 10 of ML2, I have to enter a value of 22. I am using a V130 on an application where I shift around 200 bits to the right & need to check any bit in the stream. Hence need to enter a variable in the Offset of TEST bit function.

Is the HELP wrong, or am I doing something wrong.

Ron

[TEST Bit Function]

Hi,

I am trying a Shift Logic in a V130. I need to TEST bits to enable certain Outputs. The PLC does not behave as per the details in the HELP section. In the help you have shown that in order to check bit 21 of ML2, B will need to be 21. However, in reality, B has to be 10. ??? Is the Help wrong or am I wrong?

[Serial Communication]

Hi,

I have 3 different sensors connected on the COM2 (RS 485) of a V280. These sensors are plug in types. They send their data serially via MODBUS. These sensors are of different makes & have different FIXED Baud Rates. I have utilized 2 inputs to identify these sensors on the PLC. I need the PLC to switch automatically to these Baud Rates on Identifying the sensors. I am not able to do this. Is there any way in which this can be implemented?

Thanks

Thank you very much. All I needed to do was to register it in the Vision Swapper.

[Copy file from SD to NAS]

Hello,

New 9.0 version??? Where?

Ron

There is a sample project available in the new 9.0 version.

Where you can copy SD to FTP ( Vision is FTP client ).

I also work on a project to save to a NAS.

I have configured the NAS as a FTP server.

Late me know when it is working,

I am out of time to test the hole thing

[Visilogic Serial com Trouble]

Dear Fantasia83,

I'm in trouble trying to communicate with my V570 through the com1 port of my new Laptop.

In your post you refer to your PCs COM 1 port, but in your image it shows up as COM 5. May be its due to this.

I too use Win 7 Ultimate without any problems

[SD Card & PLC application]

Hi,

If you wish to send the customer project which will be downloaded using SD card then follow the below steps:

• Open the application using VisiLogic
• Under Project menu select the option "Create project files..."
• In the first Tab "Clone File.." if you wish to create only application file then select the .V57 option and click on create file
• Then you need to put this file .V57 in the SD card in folder User_App. (Basically you can send the customer the SD card or send him the file and he will put it on his SD. (Make sure the customer SD card is formatted properly)
• Now the customer can insert the card to the PLC and from Info mode --> SD --> Application -->upload to PLC

After performing the above steps the application will be loaded to the PLC.

Another option is to use the Unidownloader.

Thanks Ofir, will try out.

[SD Card & PLC application]

Hi,

Had done a project using V570, due to some reason, the program in the PLC was corrupted??? I need to send the same program on a SD card to the client. I do not have a V570 with me. I do have a few V130s. Now without a PLC, can the program be dowloaded from Visilogic or any other utility onto a SD card? If yes, then HOW?

Kindly reply ASAP

[Jazz Communication Problem]

Hi Joe, Not all Serial to USB converters work with Jazz. You will need the Converter specified by Unitronics. With Vision PLCs and even with M90/91, any type of Serial to USB will suffice. Ron
