  1. Mitsubishi GTDesigner 3 Alarm Summary

    I believe alarm ID allows you to set up separate alarm histories, but all of my systems that is just left at 1 (and also set to 1 in the User alarm observation) Under the Alarm Display > Setting Tab > Make sure Display Target : ALL ALARM, this should show all current alarms
  2. GX Works 2 Menu Dragged off Screen

    You can either reset everything OR if possible connect to a larger resolution screen.  I have this issue all the time bc at my desk (QHD Sreen) i set the cross ref list on the opposite screen. But then line-side that list remains off screen. 
  3. instead of using FIND for the D10020 address, which will only show contacts or coils directly addressed as such.   use cross reference. That will show any place that address is used in Bulk moves See examples from my program. 
  4. serial input string

    OH yeah of course good catch.  I don't know why XOR was in my head.. 
  5. serial input string

    This function does exist, and its EVAL     You will have to clear that "G" with a XOR "FF00" D200 first
  6. serial input string

    OH going from ASCII String to numbers... not sure that happens without some ASCII lookup table    What control do you have on that the input field / method?  It would be better fix the data source than write a algo to convert
  7. serial input string

    will this string always start with "G" ?  If so, Change your HMI input to be Float input and just add the G as a prefix visually If not, then a block move (BMOV) starting at the second register of your string address would drop the first characters. 
  8. Unknown operations

    Yeah if a pointer is calculated/used in more that one place then monitoring is bascially useless for the pointer & the registers its pointing.  there are 20 Z available but it seems everyone only uses Z0.  lol.  I will share a Z only if the functions are related & exclusive i.e. reading & writing from a array. Where only 1 option is ON at a time. 
  9. PLC Reset?

    Yes, you would want to add a start/end address that would be retained always. If memory space allows, i would just set this to the entire range of D. If not I typically would use 10,000 - end, that way I know the data location is up out of range with the rest of my address mapping. I believe the HMI can have it's own memory, but I don't utilize that so i am not 100% sure.  
  10. PLC Reset?

    Project navigation  PARAMETER > PLC Parameter.  Then select the device tab. Any data points listed under Latch 2 Start - End will remain through power outages / reset.
  11. YASKAWA v1000 plc

    I would check the physical motor install, verify bearings are good, check runout / alignment, things like that would cause the drive to be working too hard. Also recommend plugging into the drive and using the software to monitor the drives performance. it might point you in the right direction.
  12. Rural public water system in TROUBLE

      With that low number of I/O  I would bet its mostly an order of operations & timer based system. It might be a good idea to try to create a map of the functions you KNOW it does and build from there.  A scope or meter on the outputs to get a timing and order. if there is a HMI look for any settings / parameters.
  13. Data register lost when the power is off

    Glad to help.
  14. Data register lost when the power is off

    PLC Parameters > Device Tab. Set a start / end address for the Latch 1 / 2 as needed.  Latch 1 is data retained during power cycles but reset with Latch clear command. Latch 2 retains data always.
  15. PLC to PLC

    I created this program to help me remember how to set this up. EthernetLink.gxw
