[Errror Loading Visilogic]

I would recommend a full uninstall. If certain folders were not removed during the uninstall/reinstall this could be the reason you are still viewing this error.

After performing a Windows uninstall of VisiLogic the following folders must be manually removed:

• Delete the folder “Unitronics VisiLogic_C” from C:\Program Files\Unitronics
  

• Delete the folder “Unitronics” from C:\Program Files\Common Files

The new version, or a reinstall then then be performed.

[Data table csv file name]

Can you clarify what you mean by export the file? Do you wish to send it out using the FTP server?

 

When creating the CSV file from the Data Table using the Store DTI to File block you have the option to append the file in the Input parameter E. By default this value is 0, but if you change it to a 1 it will append the data without needing to change the file name.

[-1 status when sending e-mail]

Is the Default gateway correct? Can you ping any IP address outside of your network?

 

What type of email client are you using? Gmail more recently set up new security settings that need to be disabled before sending an email from a third party device.

[Variable output on/off-time depending on analog input]

This is fairly complex. How often does the output change? What if the output changes while a previous timer is running? There would need to be some way to determine when to start/stop the output operation.

 

A linearization function block can be used to scale the time output, but it will then need to be loaded into a timer block to run. Something would also need to trigger this run block.

 

What conditions are you using to start the digital output running?

[Stk Overflo]

The ladder error code you receive, 0x0000003D, can be used to find what subroutine is causing the crash. This can be found in VisiLogic under the Edit menu then selecting Find Subroutine by Ladder Error Code.

 

A file size of 217MB seems too large as most of our project files are from 1MB to 20MB normally.

[GW-BAC1 BACnet Gateway]

Yes, this is a current product. There are not any tips as you only need to upload the file to the gateway after creating it with the configurator. There are instructions in the manual which you find linked below:

 

http://www.unitronics.com/docs/technical-library/gw-bac1.pdf?sfvrsn=0

 

A Unitronics PLC will be set up as a Modbus master over RS485 or Ethernet and communicate to the gateway. The gateway has it's own registers and will convert the Modbus registers to BACnet registers. This then allows any BACnet device to also connect over RS485 or Ethernet to read/write information to the gateway.

[Testing code before deployment (hardware simulation)]

It is required to have the PLC to run any ladder logic or HMI operations for all of our products.

[change text from button]

You can use the text element, List of Text by Pointer. This allows a list to be created for text such as Running 100, 200, 300 etc in different rows. Only one set of text will display at a time. This List of Text element is linked to a numeric variable used to display the desired row number. For example if a #0 is entered than it would display the text in row 0 for Running 100. If a #1 is entered it would display Running 200.

 

Each time you press the button store the corresponding row number into the variable in the List of Text element.

[multi program.]

Only one program can be working in the controller at a time. If you have access to the program you can add additional code if the two tasks can be combined.

[V280 - best way to create log of informations?]

We do have both email and phone support with telephone numbers for both USA and international support.

[V280 - best way to create log of informations?]

As you mentioned the best way would be to use the data table features in VisiLogic. They allow you to structure the table with any information that you need and both read and write information to the table. If you need additional storage you can utilize the SD card for additional space.

 

There isn't a built in history feature to scroll through a table, but you can read information from the table into elements on the HMI. The read row button does allow you to modify the row being read, which can allow you to "scroll" through reading different parts of a table. Buttons can be added for scrolling that would increase/decrease the row number being read.

[USB Infinite Reboot - Windows 7]

The issue sounds like Windows is not recognizing the hardware and not applying the driver correctly. Are you able to connect using an Ethernet connection? The panel has a default IP address of 192.168.1.2, though this can be changed in Network settings in UniApps by pressing and holding the top right corner of the UniStream's HMI.

 

Please try the following steps to see if this resolves your issue.

 

·         Power OFF the PLC

·         Close UniLogic

·         Unplug the USB cable

·         Make sure the PC is grounded (power supply for notebook)

·         Power ON the PLC

·         When you see the "initializing" green spin logo, plug the USB cable

·         After the PLC finished to Boot up,  Open Windows CMD > ping 169.254.100.1 and see if you have a reply from the PLC

·         Open UniLogic and try to download a project.

·         If needed, In the discovery window click on the "Refresh" link few times 

 

If this does not solve your issue please send an email to support@unitronics.com

[UIA-0800N resolution at 4-20mA]

This is correct. The resolution is maintained, and the option allows for the lower and upper scaling limit to directly correspond to 4 and 20 respectively instead of 0 and 20.

[Video animation after boot]

The resolution for the UniStream 7 is 800x480. Though if the video element is drawn smaller than the full size of the screen this could also cause scaling issues.

[Pictures not shown correct after software upgrade]

No, this is not a common occurrence and should be resolved the first time you perform the steps listed.

[How download a program for one PLC with Unilogic??]

Which version of Windows are you using to run our UniLogic software?

 

Is it limited to communication with a single PC, or can another one communicate with it over USB?

 

Please try the following steps:

 

·         Power OFF the PLC

·         Close UniLogic

·         Unplug the USB cable

·         Make sure the PC is grounded (power supply for notebook)

·         Power ON the PLC

·         When you see the "initializing" green spin logo, plug the USB cable

·         After the PLC finished to Boot up,  Open Windows CMD > ping 169.254.100.1 and see if you have a reply from the PLC

·         Open UniLogic and try to download a project.

·         If needed, In the discovery window click on the "Refresh" link few times 

[Video animation after boot]

It is possible if you have a video on the start up page. You can then load to a secondary page afterwards.

 

Playback quality may be dependent upon the software used to generate the video. What size UniStream are you using? The resolution may be slightly larger than the HMI can provide which can cause distortions when it needs to be re-sized. I would recommend having the video resolution match the element size on the HMI to see if this improves performance.

[UniStream simulator]

Currently it is still required to use a UniStream PLC in order to test the code.

[Bits array memory area]

The option to create a project with the Pre-defined operands will automatically create sections of tags for you, similar to how they are set up in our VisiLogic software.

 

Otherwise a regular project has memory to use and build from as you go, but each tag can be added manually only using the required amount of memory.

 

The difference between the MB's and XB's are that MB's are retained memory while XB's are not and will be reset to 0 when the controller cycles power.

[UIA-0800N resolution at 4-20mA]

The resolution is still retained at 13 bit when the 4-20mA selection is made. It will still have the default 0-8191 available, though you can manually enter the min and max value should you wish to scale the 4-20 resolution into real world engineering units. This allows you to bypass needing to implement a linearization block within the ladder.

[Drop down selection menu]

The Vision HMI displays do not have a pop up option. Having each selection button open a specific display for that option would be the best way to re-create this feature.

[Struct description not updating in Global tag]

Currently the description field is only carried over when the instance of the struct is created. Should you wish to have different descriptions this allows you to edit the descriptions field and then create another instance. Otherwise all tags using the same struct type would have the same description.

 

Should this be an issue please contact support@unitronics.com

[Bypass communication pasword]

If it is the block PLC access password you will need to contact the person who downloaded and created the previous program.

 

This password was set up as a safety feature in which you must know the password to communicate with the PLC.

[Change meter fill color from Ladder]

The fill color for a bar is not possible to dynamically change, but there is a way to accomplish what you need.

 

Since it is possible to layer different elements on the HMI in UniLogic you can place multiple meters placed on top of each other. Each one being a different color. You can also use the hide bit on each element to hide the meters you do not wish to see.

 

For example have the green meter showing normally. When the value is below 50, hide the green meter and then enable the red meter. Both meters will still be linked to the same tag value.

[Any way to change controller type for a program?]

You should be able to convert from one HW type to another simply by changing the hardware configuration to another part number. This should work from Jazz - Jazz units, though please know that since I/O configurations are different if you transfer from one project to another know that some I/O information in the HW configuration may be lost or need to be re-written for analog channels.
