  1. Barcode string parsing

    The basics are: 1) Use the FIND$(660) command to return the position of the first comma in the string in hex 2) Use the LEFT$(652) command to extract the characters to the left of the comma to another string You will probably want to subtract 1 from the hex value returned by the FIND$ command so that you don't get the trailing comma when you use the LEFT$ command. You may also want to use the DEL$ command to clean up the data left in the receive buffer.
  2. ZCP Instruction

    Try using the mnemonic  P_EQ which CXP interprets as the Equals Flag.
  3. CJ1W-AD041-V1 - Damaging Channels

    I suspect that the signal coming from that transducer is not DC but is an AC signal and that the high voltage peaks on the signal are destroying the AD041 module input channels.
  4. IP/ Subnets and communication between subnets

    Your problem is the subnet mask. With a mask of PLC1 can only talk to other devices in the 10.125.34 subnet. If you set the mask to like the other two PLC's it will work. You really should do a little research into how subnet masks work. subnet tutorial
  5. Moving values to memory

    Take a look at the BSET(071) instruction. It should do what you want.
  6. PLC' down?

    It appears that they are having the same problem again today. I am unable to access the site.
  7. PLC' down?

    It's working now. Apparently they went down around 3:00 AM and came back up around 2:45 PM.
  8. New content Icon???

    It is working OK again.
  9. New content Icon???

    The exact same issue is back again after being gone for over a year.
  10. CP1E Allocation I/O

    That depends on which model of the CP1E you have.
  11. HR AND W

    "H" bits retain their state when the cpu is stopped or powered off. "W" bits are reset to OFF when the cpu is stopped or powered off.
  12. MicroLogix 1400 to Maple Systems HMI

    Yeah, version 2.10 is quite old. I'm a bit surprised that tech support didn't have you check the version. There were a few serious bugs in those early versions of EBplus. Version 5 seems to be pretty stable.
  13. MicroLogix 1400 to Maple Systems HMI

    Have you talked to Maple Systems tech support??? My guess would be that there is a problem with the DF1 driver.
  14. unknown text

    You might try checking the font settings under Tools/Options/Appearance to see if they somehow defaulted to the wrong font setting.
  15. Trace Function?

    You need to display the "Address Reference Tool" window on the CX-P screen. Each time you select an object in the program by clicking on it that window will display every program rung which references it. When you click on a reference in that window it will take you to the corresponding rung in the program.
