  1. I am not 100% sure what you are referring to, but I started poking around in the protocol send FB trying any possible options that could result in the previously entered string variable (product name) rebuilt from a vector of integers which are stored in the data table. The solution was to stream the vectors of MIs from the data table, converting one linked register to two bytes. I feel this is far from being trivial, maybe there was an example to demonstrate this operation or maybe there is a far simpler way to achieve what I was trying to do. 1. String variable entered by operator 2. MI40-MI 49 (20 characters) saved in a data table 3. reading the content of the data table and decoding the integers to pairs of characters 4. As a result, I finally see the decoded product name in the serial printout. Yay ! Do you think there is an easier way to print the user entered string variable to the serial port ?
  2. Using Visilogic 9.8.65. I have a project where a product recipe name is entered as a string and stored in a vector of MI integers (via the string variable edit box). The recipe name (integers) is stored in a data table. When the machine is running, from time to time it outputs the name of the recipe and other recipe parameters to the serial port. Currently I have the send function configured to send the line id of the data table, because I cannot seem to find an easy function to send the characters to the printer. It would be more meaningful for the operators to see the name of the product on the printout instead of looking at a numeric value. How do you send a user editable, variable string to the serial port ? Thanks
  3. In case someone else runs in the same situation: I ended up testing the I/O voltages of the inverter, input was ok at ~5VDC, but there was no high voltage output. As a secondary test, I hooked up the input of the CCFL backlight to the inverter of an "old" laptop LCD... and the PLC screen came back to life ! Since the original hitachi invc695 seems to be obsolete (and overpriced $100-$300), I ended up buying a "universal"/laptop ccfl inverter for <$10. Should be a smooth sail from here: some hand soldering then securing the universal inverter (no mounting holes on the pcb).
  4. Hi, I have a mostly functional v570 that I would like to refurbish to build a demo machine. Unfortunately, the LCD ccfl backlight inverter is shot and the screen does not turn on but the rest of the PLC is fully functional - which I confirmed by connecting over COM1, updating the OS, downloading a new project, monitoring/controlling registers/IOs, reading touch coordinates/toggling the onboard buzzer, etc). I am very interested in ideas how any of you were able to resurrect dead LCDs. (This is not a question about the boot / blank screen issue, I know how to recover from that. This is a hardware issue with a bad ccfl backlight inverter (or bad LCD). and/or If any of you happen to have a functional v570 CCFL backlight inverter (hitachi invc695) or an LED backlit LCD/driver combo and willing to donate or exchange it for a fully functional V120-22-UN2 model, please let me know. Thanks
