  1. Pair of typical Old Phfarts Jay - no patience - has to happen NOW! LOL
  2. Bugger! Too slow - never be quicker for mine. Came up with DOS software - typing in an I/O address wins hands down compared to symbols. Anyway! Must be getting old and grumpy!
  3. What a ruddy pain! IEC crap! Sticking to the CJ2M and CX-P for a lot of reasons. Bloody European requirements are a load of rubbish for mine. Way to slow to program. Studio is really a PITA. Give me CX-P anytime. Sorry - not helpful but how I feel - must be getting old and cranky! And I have to program a Schneider redundant system shortly - very painful also.
  4. Can't modify memory

    You can only write to the PLC and transfer data when in monitor mode or program mode. Put the PLC in monitor mode on start up and all will be good - monitor mode is the same as run mode except you can write to it and do online program changes. Settings as attached and write to PLC.
  5. Device Types, where are they?

    You can probably get it here https://industrial.omron.eu/en/services-support/technical-tools/downloads/download-software-cx-one-trial-version
  6. Update CX-One and it works fine. Been using it since Windoze 10 came out.
  7. Omron CJ1W-ETN21 Redundant

    No - Modbus only has one master. I have managed to organise 2 Modbus masters in a Red Lion protocol translator though - not the same.
  8. Your previous post about this has been answered.
  9. And people wonder why I will not use the new ones! Sticking with CJ2 and CS1 - oh and CP1. I program on the keyboard using numbers - symbols are stupidly slow! I have a job to program with Schneider - symbols - painful - if you want to use the keyboard %I. then rack number - then slot number - then bit number! Studio is not much better!
  10. Scale Encoder Reading to 0 to 359

    OK - it is just that the last encoders I used were scaleable in the encoder - made it easy.
  11. Scale Encoder Reading to 0 to 359

    In the encoder?
  12. Fatal Error?

    Perhaps the peripheral port is dead. Check the manual - you can set the serial port to a default value and try again with a serial cable? Just be careful - the Omron serial cable is not standard. cable is 2-3, 3-2, 4 & 5 tied together at the computer end and 9-9 if I remember correctly - check and make sure - I have not used a serial cable for many years.  
  13. Fatal Error?

    You need CX-Programmer. You will have have to re-create the I/O table.
  14. CX-Spervisor Dev V3 WANTED TO BUY

    Contact Omron or a distributor.
  15. When will I use CIO and Work bits?

    W or work bits are just non retentive internal bits - known as M bits in other PLCs. CIO is common I/O bits and are used as inputs, outputs, and non retentive work bits as well. I rarely use W bits but just use CIO for most of my programming. You can also use the W area as non retentive words, as you can with the CIO area. The ability to access the D area as bits is only fairly recent - CJ2M if my memory is correct. D and H areas are both memory retentive.
