I'm sure the next question someone asks will be, "What happens if I migrate from a V1040 to a V570/V350 project?"
A:
If you have a fully populated V1040 HMI and then switch hardware configs to the smaller resolution V570, you will get the warning below.
Basically everything is okay in the top left portion of the screen when converting. Other information outside of that top left square will be lost.

From where I can download the version of visilogic to program the V1040?
Thanks.
Greetings.
Currently as of today (17/12/10) an official release of VisiLogic that supports the V1040 has not been issued yet.
If you would like to start programming, below is a download link to the beta version of VisiLogic 9.0.0 (also included on CD in the box) for the time being.

Please try the "Delete SD File" function block. It allows you to specify the folder of the the file you would like to delete on the card.
SD --> SD File Utilities --> Delete SD File

If the firmware ever becomes corrupted or you receive a blank beeping screen, the instructions below will fix the problem 99% of the time.
Please put the controller into bootstrap mode and then follow the instructions below for manually reinstalling in “advanced†mode the firmware on the controller.
Be certain to use the max baud rate of 115,200 and physical port 1 of the PLC.
To Enter Bootstrap Mode:
- With the power to the PLC turned off, hold your finger down on the touch screen and plug the power in.
- With your finger still pressed down count for five seconds, then release and tap the screen twice.
Try individually installing first just the Bin Lib, then just the Boot, then just the O/S all while in bootstrap mode.
In between each step VisiLogic will ask if you want to send a run command, select no each time.
After going through this three step process of Bin, Boot, O/S normal operation should be restored.
- With the power to the PLC turned off, hold your finger down on the touch screen and plug the power in.

Connecting to 3rd party HMI screens, either over serial or ethernet, is a relatively easy task.
The most common way to talk between our PLC and the external HMI is to use the MODBUS protocol (RTU or TCP) to transfer data.
Generally the Unitronics PLC will be the MODBUS slave and the 3rd party HMI will be the master polling.
If you look in the examples folder of VisiLogic you will find full working applications for implementing MODBUS with our PLC's.
FYI: We are releasing a 10.4" color touch screen PLC+HMI soon. (Vision 1040)

It's 0F in the office in Massachusetts. Ouch!
Its not quite that cold out yet, but in a month or two it will be!
But seriously the thermocouple wire just came undone when i was moving the plc around to get it back up and running
-
we're back up and running now for all those interested

It appears IT has blocked the port forwarding on our network. I am trying to work with them now to get it fixed...

You can try putting the PLC into bootstrap mode and reinstalling the OS.
To enter bootstrap:
- With the power off, hold down the <I> + <ESC> keys
- Plug power in with these keys held
- Controller will now be in bootstrap mode
- Make sure to communicate with the PLC at max baud rate(57k) and physical COM port 1
- Reinstall OS

If anyone is interested in seeing some of the capabilities of the advanced web server in action, below is the website address for the web server being hosting off a V570 with a SD card in our USA office:

Please see the attached commented example program I created.
It will take inputs 0-7, convert them to an integer register, and then perform linearization to go from 8-bit to 12-bit (0-10V).
Linearization is performed on the HMI variable to display the 12-bit value as a voltage on screen.
