  1. It's connected to a 90-30 series plc, I think it uses an ADC 311 COPROC in the rack.

    Looks like I need to recreate it all on a modern HMI.


  2. Hi

    Can anyone tell me what programming software is required to extract a program from this GE Fanuc HMI?

    Any manuals available for it?

    Thanks in advance

  3. Hi

    Does anyone know anything about the attached panel PC which communicates with a GE 90/30 PLC.  Any information about how it was programmed would be useful.  It seems to be a SCADA type application that runs on Windows 3.11 and is way past its replacement date!

    Thanks in advance

  4. Hi

    I'm using TIA 16 and S7 1200 and have a DB block set up with 20 bytes of data which I want to move to QB100 for 20 bytes.

    I've done it with individual MOVE instructions e.g MOVE DB3.DBB0 -> QB100, MOVE DB3.DBB1 -> QB101 etc which is working OK but feel there must be a better way with MOVE_BLK or MOVE_BLK_VARIANT.

    I can only find examples where data is moved from DB to DB and can't seem to get anything to compile with MOVE_BK or MOVE_BLK_VARIANT.

    Any ideas?

    Thanks in advance


  5. Hi, I have the following STL code in an old S5 processor, can someone tell me if I've transcribed it to ladder correctly please?

    :O    F11.0
    :O    F11.1
    :(    I81.6
    :AN    F11.2
    :AN    F11.2
    :O    I81.6
    :A    Q64.3
    :)
    :A    I64.6
    :A    I64.0
    :AN    F3.6
    :=    Q64.3


    F11.0    I81.6   F11.2   F11.3    I64.6    I64.0    F3.6                  Q64.3

  6. Have a word with your local vendor about logic master 90, it's also bundled on the versapro and profiecy software disks I think.  Get a trial copy of either.

  7. Step 0 is set to a type N - non-stored which means the code in the step is continually scanned, so every time you set BACKWASH_START_PB to a 1 the code in step 0 sets it back to a zero. 

    If you click the square box next to the N you can set the Qualifier to Pulse (Rising Edge) which means the code in step 0 will only be scanned on the rising edge of the step becoming true.

     


  8. Thanks for the info, I sorted it out this morning.

    The software is XBT L100 which runs on a windows 98 machine (in dos mode), its downloadable from the Schneider website.  The cable is:

    2-2, 3-3, 5-7 plus 6+4 linked, 7+8 linked at the 9 pin (pc) end.

    As you say its well obsolete but the client had purchased a spare from ebay and I needed to get the program from another unit to download into this one.


  9. I need to catch an input changing state which has a very short duration and I'm currently missing it due to scan time.  Is there a way in Siemens to improve the chances of catching a change by programming e.g. using something similar to a Selectable timed interrupt (STI) from the Allen-Bradley world or maybe a FAST TASK?

    Thanks in advance for any suggestions

     


  10. Hi, I'm replacing a system I did 10 years ago with Allen-Bradley with a new Mitsubishi system using a GOT hmi.  I'm basically recreating what I did previously so the operators don't have to learn something new.  In the old system I had a list selector where the operator would use arrow keys to scroll down the list of tanks (e.g. Tank A, Tank B etc etc) to select the destination tank, this would return a number to the PLC which would then open the appropriate valve for that tank.  I can't seem to find anything like that in the Mitsubishi software (GT Designer3), can it be done?


  11. I've backed up two machines with Proficy ME 8.5 and both show a red X on the project name. I think this maybe due to the processors containing software written in LM90 can anyone shed some light on how to resolve this. Do I need to download from Proficy ME to resolve this?
