Recorded Live: Wednesday, December 8, 2010 Presented By Anthony Nicolaides Applications Engineer - Unitronics Inc. Ethernet – Learn the basics of setting up an Ethernet connection to communicate to and program the controller. Learn about the setup and configuration of the card, and the sockets. Learn how to use the remote management tool “Remote Operator” to bring up the screen of the PLC on the PC over the network. Take a quick look at Modbus IP and see how to communicate between two controllers.

This is the case with other PLCs I have worked with. A: That address (255.255.255.0) is most common for a "Class C" Subnet Mask. But you would have to verify with a network administrator to be certain. Q: if you set up multiple sockets to html, can you have more than one person looking at the vision hosted webpage at the same time? A: web browsers default to communications on port 80, therefore the PLC must have a socket defined for this specific port when using HTML. Q: is all the same for the 1040? A: same for all Ethernet enabled controllers

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

Recorded Live: Wednesday, December 1, 2010 Presented By Anthony Nicolaides Applications Engineer - Unitronics Inc. Buttons and Lights – Learn how to work with the HMI and Ladder in VisiLogic. We will use contacts and coils as inputs and outputs for out ladder. We will link the ladder to HMI elements and see how to affect the Ladder from the HMI. We will also learn about some of the HMI tools and functions. Downloading to the controller will also be covered. This is a great first step for any new user.

A: Yes, right click and copy. Then you must next move the original button out of the original space first, since the paste will try to place the copy in the same original screen real estate Q: Can you change the background color in HMI? A: Yes, double click anywhere on the desired HMI (where no objects are currently placed) and you'll see the option to change background color Q: I have a question about where you click when activating the switches. Can you click on button on HMI or Ladder ? A: From "online testmode" you can control the logic in the ladder portion of VisiLogic. Tony has also been opening up the live HMI via Remote Access built into VisiLogic with online test mode (view menu--> Remote Access) Q: Can you connect wires between nets (rungs)? A: No, logic is required to execute its each own net. You can drag the net down by clicking the yellow arrows if you need more space in the net.

I'd like to give Bruce L credit for this interesting approach to mask the onscreen keypad entry!

When multiple password levels are needed, there are only two choices. You can create a Password Entry Button for each password level or use a Numeric Entry and compare the entered password against the password levels in the logic to set the desired levels. However, the negative to using the Numeric Entry for passwords is that the digits that are entered on the screen while the users touches the screen. This can be a BAD problem. Here is a sample program that will draw a black line on the screen that will hide the digit as they are entered. This program is setup for a 4 digit password and uses the Simple (Back) Keyboard Screen. The sample program has a normal Numeric Entry Button to show that it will not blank out the digits unless it is programmed to do so. When the Simple Keyboard Screen is open, the logic looks at the pixels on the screen to detect when a digit is being entered. Each time a digit is entered, the logic will draw the blank line over the display. Each of the four digits will be covered as they are typed. The logic also monitors the area over the "Back" button and will remove the black line covering the digit if the user presses the "Back" button. Since the Numeric Entry Button will display the number that was just entered from the Entry Screen, this logic will hide the button if it equals one of the passwords. There is a "Clear Password" button that will reset the password integer and un-hide the Password button again. The sample shows some buttons that will only show when the desired password level is entered. There are two passwords in this sample (1111 and 2222). Note: The logic detects the screen that is being displayed and the area where the Password Entry button is located. These variables will have to be changed to reflect where the Password button is located on your program. This was logic will not work on the Complex keyboard without modifying the pixel area that it monitors for the digits and Back keys. This is a starting point to customize to meet your needs. Hope you find it helpful. Original Posting Source: Multiple Passwords

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.

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)

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...

Working as a support engineer, I have noticed quite a few customers looking for this "multi-level" password feature. Now we have a nice walk through and example to point them to!

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
