  1. No. That is why there is a CPU backplane.
  2. Difference between RUN and MONITOR modes

    Monitor mode allows online program changes - run does not. I start all mine in monitor mode anyway.
  3. DT function for month and year comparison

    That is why the suggestion to do it on 1st at 00:00:00 - does not matter how many days then.
  4. Sysmac Studio won't load

    Yes - just the update program. Still not working - have to reinstall I guess.
  5. Is anyone having issues with the latest version of Sysmac Studio (1.24)? Updated today and it will not load.
  6. Add Fonts to Sysmac Studio

    Thanks Woody - I am not using the NA screens so did not know that. Maybe an improvement request?
  7. Add Fonts to Sysmac Studio

    Have you installed the font on the computer? CX-Designer uses the Windows fonts. I like using Khmer UI - nice and clear. It is not in Windows 10 but can be installed and utilised.
  8. Lost Data Memory and SCU Settings

    Is it possible the machine is shaking the PLC causing the bus connectors to disengage? Have you taken the PLC apart and reconnected the bus? Is it possible that the connector slides are not made properly? I/O Bus Error is often a mechanical issue like this.
  9. Lost Data Memory and SCU Settings

    No - the data memory is backed up by a battery.
  10. MOVD

    I thought you could use MOVD to move digit 2 to digit 4 in another word and so on. Just have to do one at a time? I also thought you could use MOVB to move multiple bits in the same way? Have not used either for many years so not sure but worth a look?
  11. Yes - but if not powered down not a problem. Can be re-written from the screen anyway.
  12. Here is a bit more - this is to turn pumps to night speed and day speed. The hour and minute values are written to D2020, 21, 22 and 23 from a touch screen. the SWAP function is used to swap the minute bytes to make the comparison easy. ANDW is really very easy to use and I use it here as a mask to block hours and let through minutes and to block minutes and let through hours. While the settings are in HEX they are actually read in binary - HEX is a leftover from older Omron PLCs to allow those programs to be easily converted to newer PLCs I believe. The settings in D2020, 21, 22 and 23 are actually HEX values. Time Clock.cxp
  13. Here is how to extract minutes and hours to separate channels with a mask.
  14. Declare an Alarme

    That is the HR area - holding relays. If in CIO select CIO from the drop box then the channel and bit number on the right - easy as.
  15. Declare an Alarme

    Just type in the address e.g. 300.01.
