[Loading a program via a USB memory stick]

Hi Gary, Noam,

You can load a Program via a USB Stick by navigating to Download > Export project to USB storage, as Noam suggested.

Using UniLogic, a user can view live data in the controller using the Online mode. However, online edits to the program are not available in this mode. The edits must be made offline and downloaded.

[Does forcing SB 300 ON brick the Vision PLC?]

Hi Schafbo,

 

You can place the controller into OS stop upon power up. This will stop the PLC from running the program.

 

From there, you can can load a new program.

 

Power-up modes are outlined in the help file. 

 

Hope this helps!

[V430 ASCII keypad wrong]

Hi Gabriel,

 

There doesn't seem to be an attachment, could you post it again?

 

Thanks!

[Consecutive coils connection]

Hi OrdosDeviator,
 
The example for the second should work, assuming this is the only coil for the output. 
 
Is there another coil for the output? Is so, the coils will conflict, and the last coil will control the state. 

 

Please feel free to post your project and I can test.

[Reset to factory settings]

Hi Kris9880,

 

What type of Unitronics PLC do you have? Each PLC has an option for BootStrap mode and Stop Mode. Instructions on how to get to these modes vary between controllers. Within these modes, the program stops, and the PLC communication settings are reset. 

 

What are you attempting to do in this mode?

 

Thanks, 

 

Dan. 

[Lost in variables]

Hi Vidmas30,

 

It appears the issue is with signed and unsigned 16 bit registers. A MI is signed 16 bit register, with a range of -32768-32767. A unsigned 16 bit register would have a range of 0-65535. A 65535 for a Unsigned register will result in a value of -1 for a signed register. 

 

The bits will still translate directly, however. You can read the value, and break the value down into bits using the function block Vector > Numeric to bits.  It will take the MI, and break it does into MBs.

 

Alternatively, a DW is a 32 bit Unsigned register. 

 

I hope you find this helpful.

[Forcing Analog values]

Hi Joesteva,

 

There is no way to force a analog input within the software without supplying current or voltage to the terminal. 

 

What I would recommend is to create a new "Test" tag, and replace the analog input in your code with this tag. Once this is done, you can change the "test" tag to simulate an incoming value.

 

I hope you find this helpful.

 

Thanks, 

 

Dan. 

[Modbus to Siemens 353 Controller]

Hi Dan,

 

Are you using Real numbers? We have similar issue using Real numbers. 

 

A real is a 32 bit register. In our case, the UniStream and Siemens controllers did not interpret the 4 bytes in the same order. (i.e. 8e1 is interpreted as 81e0, or the like) This results in different values. 

 

In the UniLogic software, there is a function block that will swap the bytes. This worked; however, if there are not sequenced properly, it will result in "flickering" of the value between 2 values. 

 

A similar issue can occur with Integer values as well. 

 

Please feel free to email us at support@unitronics.com for further information.

[Access PLC from mobile phone]

Hi Marius,

 

My suggestion would be to utilize the webserver, as a smartphone can access internet browsers. 

 

The V1210 supports both the simple and advanced webserver. The simple webserver is a template, the advanced allows the user to build HTML pages. Additional information available in the webinar. 

 

I hope this helps,

 

Dan. 

[Unistream CANopen config]

Hi,

 

Thanks for using the Unitronics forum.

 

The TPDO and RPDO will use Structs created within the project. First click the "Struct" tab in the tag database, and create the format of your RPDO. Once created, you will have the ability to create a tag with this Structure in the RPDO and TPDO tabs.

 

I hope this helps,

 

Dan.

[Comparison function block issue]

Hi Navigatoru,

 

Is the compare statement is a subroutine? Is the subroutine running?

 

Is MB50 used elsewhere in the application? If so, try to link a new unused MB. It may be that MB50 is controlled elsewhere in the application. 

 

Thanks,

 

Dan

[Reading inputs.]

Hi Paul,

 

Please note that you can use input directly in the ladder. 

 

But if you do require these registers to be moved, you can accomplish this using a vector copy tool (located in the vector dropdown menu). in your example, copy I0 to MB0 with a length of 8.

 

Thanks,

[Application Error]

Hi Pete,

 

Please send the application and image to support@unitronics.com at you convenience so that I may review and simulate. 

 

Thanks,

[Application Error]

Hi Pete,

 

Is this occurring with a particular project only? Can you open a new application and simulate?

 

Also, it may be worth running the software as admin to test. 

 

thanks, 

 

Dan. 

[Application Error]

Hi Petercolquhoun,

 

What is the OS of your PC? (win7/win8/vista?)

 

Please ensure that you are running the software as administrator. (right click on visilogic icon > run as administrator). You can also set the software to run automatically as admin in the properties for the visilogic. 

 

please update us on the results. 

 

Thanks,

[Force Digital input]

Hi,

 

A digital input can be forced from the VisiLogic software and using the info mode of the controller. 

 

Visilogic- Go into online test. Double click on the input you would like to force. Right click and the click "force to 1".

Info mode- Enter info mode of the controller. Select the operands > Inputs. Select the input you would like force and click F1 at the bottom of the screen.

 

Please note that you must clear the force when done.

[IO-D16A3-TO16 Output 0 Physically on, Visilogic says it is not]

Hi,

 

If you are using a PWM output, the duty cycle will determine the percentage the output will be on for over the given frequency. (0-1000).

 

If the duty cycle is set to 1000, then the output will always be on over set frequency. 

 

Try setting the duty cycle to 0 and see if the output is still on. also, attempt to set a frequency of 1000 to test.

[SAMBA expansion IO]

Hi bdarden,

 

The samba does not support expansion IO. Only the remote adapter, the EX-RC1. 

 

thanks,

[EX-RC1 wiring topology]

Hi Gabriel,

 

A daisy chain topology is the correct way to wire a canbus network. Termination occurs at both ends of the line:

 

TPLC- Terminated PLC (Or EX-RC1)

PLC- Non terminated PLC (or EX-RC1)

 

TPLC----PLC-----PLC----PLC----TPLC

[Cannot Move Objects on V570 Editor]

Hi Degreeless,

 

There is an HMI icon to lock the HMI display. It locks the display so that nothing can be changed. The Icon looks like a lock, and is under the word "tools"

 

please contact support@unitronics.com if the issue persists.

 

Thanks,

[new vision570 model v570-57-t20b-j]

Hi Perry,

 

Please contact support@unitronics.com and we would be happy to assist further. 

 

If you power down the unit, hold you finger on screen, and power the unit up, does it enter bootstrap mode?

 

Are you using any additional serial ports?

 

thanks,

[JAZZ & program protection...]

Hi Magnetron,

 

The D90 file is created during download to a Jazz controller. In order for the file to be created, a connection to the Jazz controller is required. 

[Debugging - Step thru one net at a time?]

Hello,

There is a troubleshooting tool that will allow you to view a portion of the ladder. The tool must be placed in the ladder before the option will be available. It is located under util>debug>online-point and interval.

thanks,

[I would like the ability to toggle between celcius and farenheit]

Hi Tectron,

The HW configuration can only be set for EITHER C or F. However, calculations can be done in the ladder using the math functions to convert one to the other. Once both C and F are stored into seperate operands, they can both be displayed on screen (or switch between the two).

Thanks
