    ALWAYS use transition contacts to call HMI screens.
  2. Flex727
    The only way I know of is to use the "List of Images by Pointer" HMI element.

    SB 2 will activate any ladder rung it's placed in on first scan, no matter where (as long as it's called). It doesn't have to be the Main Routine.

    All registers and coils are retained through a power cycle if there is a working battery in the PLC. Just make sure that power-ups do not interfere with what you are trying to do.

    It would be lost either way. Reading the filename from the field in INFO Mode onto the HMI screen does not solve the problem you present.

    Download first. This is not necessary, but with a new PLC I like to download a blank project first, do an Initialize & Reset, then download my project. This makes sure all memory in the PLC is cleared out.

    That would definitely be cool!

    I agree with JohnR, but if I knew any English I wouldn't spend my day talking to computers.

    Agreed, but I believe this is a real business and this is a real controller in operation. The business is called Dark Matter in Chicago (a coffee house and roaster). If there are any forum members near, it might be fun to drop by and take a look.

    If you're using Vision PLCs, Remote Operator on the PC is probably your best option.

    @Joe Tauser, did you get that from my video file or from your own TV? I thought the camera lingered a bit on the V570 and gave a momentary thought that this might be "product placement", but I seriously doubt it.

    We need to know which PLC, what version of VisiLogic, what communications method, and what physical connection you are using. It would also be helpful to know if you've tried other connection methods and if you were able to connect previously, and if so, what changed? Also, are you trying to connect to a new PLC or one that already has a project loaded?
  13. Flex727
    Which PLC are you using? If it has an SD card slot, that might be your best option.
  14. Flex727
    You're not calling the subroutine "Run logic" in your Main Routine (which you ill advisedly renamed to "Inputs").

    I totally agree with Ausman and NEVER upgrade the firmware of a working system. However, it's not likely to hose things, but my motto is the same as the engineer's creed: "if it ain't broke, don't fix it".

    If you have access to Netflix, find the series "Easy", go to Season 1 Episode 3 about a minute in.

    This will NOT provide the values of those operands, however.
  19. Flex727
    Do you see a download link in my post just above?
  20. Flex727
    That is a HUGE program. It would take hours to go through it in detail. You will need to identify the settings you're asking about. As a general rule, any value entered from the HMI is either stored in a register (or Memory Bit) or a Data Table. Both will be retained as long as either 24v power is applied or the battery is good. Review the Help file regarding Operands to familiarize yourself with Unitronics PLC operational memory. If you have any concerns, then do as Gabriel Franco suggested above.

    The way you set the IP parameters in ladder is to use the TCP/IP Card Initialization Function Block. In that function block you can hard code the IP parameters with actual numbers that do not change, or you can enter MI addresses which allow you to change the IP parameters at any time by changing the values in the MI vectors. You can change those values via HMI or enter the values through INFO Mode. Once you have entered the values into the MI vectors, then the PLC will retain them unless the battery dies with power removed from the PLC (battery lasts about 10 years). You can also set the IP parameters directly via INFO Mode if there is no TCP/IP Card Initialization Function Block in ladder. Even if there is a TCP/IP Card Initialization Function Block, you can change the IP parameters via INFO Mode, but they will only stay in effect until the PLC is rebooted (if the FB is activated by SB 2).
  22. Flex727
    You've lost me now. Maybe you could post your program or explain again in different words what you're trying to do.
  23. Flex727
    If you initialize the TCP/IP card with MIs, then you only need to enter the data once, not every time you start up. You can also enter the MI data through INFO Mode if you wish instead of with HMI user input.
  24. Flex727
    Do you have the .vlp files?

    The Snap-In I/O module snaps directly onto the back of the V570 PLC. It's a convenience. The I/O Expansion modules offer more flexibility and a greater number of I/O points but must be mounted on a DIN Rail. Otherwise there isn't much difference - the biggest difference being that the I/O expansion modules have lights for each digital I/O which can make troubleshooting a bit easier. Your first task in identifying I/O modules is to list all your needed I/O points, both digital and analog, and any communication requirements.
