  1. NS Screens Using The Buzzer

    Hi lostcontrol - do you mean as in a macro or something like that?
  2. 2 x CJ2M-CPU31 and Ethernet IP

    Silly question time. I am looking at a job where I will have to use Hirschman or some other brand of switch for Ethernet IP I/O that will form a ring - they are about so that is OK - have done it before. The other issue is that I have to have 2 x PLCs in 2 different cabinets on the network. Each will be in the ring and the standby PLC will have a dry contact input from the duty PLC to turn the outputs off - warm standby. They will not accept the CS1D as there is only 1 rack in 1 cabinet. Question is can I have 2 PLCs scanning the Ethernet IP I/O at the same time? I can see no reason why not but may be wrong. Another issue I would have is that there is to be monitoring by a BMS system Modbus TCP. Each PLC would have an Ethernet card with the same IP address which would cause a clash on the network. Is it possible to make the Ethernet card in the standby PLC 'invisible' while in standby mode when the dry contact is on from the duty PLC and then when the dry contact turns off make it visible and make the Ethernet card in the duty PLC 'invisible'? Schneider do this internally in the M580 hot standby system. My only other option is the very expensive Schneider M580 system. Any help appreciated.
  3. 2 x CJ2M-CPU31 and Ethernet IP

    Thanks Michael - I think I will have to go to a dedicated PLC for this unfortunately. Schneider have the M580 and Emerson appear to have one as well. Will investigate further today.
  4. 2 x CJ2M-CPU31 and Ethernet IP

    Sadly I did not know Jay had passed away. We have had discussions over a long period of time - since I joined this group actually. I have run Ethernet switches in a ring before - no issue there. Will have to dig further I guess. Thanks.  
  5. 2 x CJ2M-CPU31 and Ethernet IP

    Will rephrase - original post is all over the place like a mad woman's breakfast! Old Aussie saying. I want to put 2 x CJ2M processors on the same Ethernet IP network - both will be scanning - they will have different IP addresses. I will have to use a standard CJ2M and an Ethernet IP card due to the final configuration - too many drops for the onboard Ethernet IP - over 16. Each PLC will also have an ETN card for access by a building management system via Modbus TCP - need the ETN for that as the FB uses sockets. A dry contact to go from the duty PLC to the standby PLC to disable outputs but not disable scanning. Also need to disable the Ethernet card as both ETN cards will have to have the same address eventually for the building management system. When the duty PLC is in control its ETN card will have address 192.168.250.3 for example. If the duty PLC falls over the standby PLC ETN card will also need the address 192.168.250.3 for the building management system. It would be possible to write the address to the DMs for the IP address but the problem I see here is the rotary switch on the front of the ETN would have a different last octet number than the number written to the DMs and would cause an error. Is it possible to turn on a bit to tell the PLC to ignore the rotary switch so there is no error? Also is it possible to have 2 x CJ2Ms in the same Ethernet IP ring scanning all the I/O? Eventually there will be 23 x Ethernet IP drops back to the processors. Michael Walsh? Jay Anthony? Hi old fella from another old fella.    
  6. 2 x CJ2M-CPU31 and Ethernet IP

    After reading some more documentation it appears that the M580 actually swaps Ethernet addresses to N and N+1. Is there a way to do this at all please?
  7. CX-One V1.1

    You will not - that was in 2006!
  8. CX-One V1.1

    I have finally downloaded CX-One V1.1 from the European website. 3 files approx 600 meg each. The files have an iso extension. How the devil do I install V1.1 from these iso files? PDL, I understand you have done it. Very keen to see what they have fived - hopefully the "hanging" problem with the I/O setup module.
  9. It is dead! The bus has a problem. Replace it with a CJ2M.
  10. Error while opening .cxp file

    Second go with a post - please post once. I commented on your other post - crap file - will not open here either.
  11. Have spoken to our local Guru and I understand I can hook in to a SCADA network where there is either and SNTP or NTB time clock server. The PLCs can be setup to automatically update time from the server. The problem is I then have to update the time clock in NS screens automatically from the PLCs. The SAP for this is operated by a button press but I have to do it automatically. Currently there are 13 PLCs on my network and this will eventually increase to 19 PLCs. Each PLC has an NS screen attached serially. Have a heap of info floating around peer to peer set up with the excellent network configurator software. Has anyone figured out how to automatically update the time, and possibly date, in an NS screen from a PLC? The PLCs are mostly CJ2M-CPU33 but one PLC is a CS1D duplex jobby. That one is the interface to the other network.
  12. I hope so - have to do things for the lowest common denominator here and that means easy ladder LOL. And I/O numbers. I have enough trouble here with my largest client trying to get him to understand a bit counter and screens? Painful sometimes. The main reason I have not bothered venturing into 'the dark side' with the new stuff. I once used Network Variables - never again - had him on the phone for many hours trying to sort him out. LOL
  13. CX-P PLCs being phased out? That is news. The CS1D redundant processors with FB programming are pretty new!
  14. Cpu dulpex notwork

    Have you tried pressing it again?
  15. Cpu dulpex notwork

    I recently completed a job with a CS1D using the 67HA processors and the peripheral port for programming and the program was transferred to both CPUs every time. It appears you have the switch set to duplex - have you tried pushing the INIT button at all? I cannot remember what it does.
  16. Cpu dulpex notwork

    I do not know if you can write to both CPUs using a serial cable. I normally use the peripheral port and it works OK.
  17. Cpu dulpex notwork

    Check the DIP switch settings in the manual.
  18. Omron PLC diagnostics

    Which HMI? If Omron NS have a look at smart active parts.
  19. I have not ventured into SS yet but I find CX-One is absolutely no issue in straight Windows 10 x 64 bit at all. It has always worked well.
  20. I have a CJ2M having the time and date being updated from an SNTP time server - working fine. There is an NS15 and an NB10 screens in the system. Both have to have their time and date updated from the PLC automatically. Any ideas? Have not been able to get it to work. By the way I have not even been able to update the time in the NB screen at all - I do not usually use these but it is for a customer who has used one. Any idea how to update the time and date at all even without this method?
  21. Update Screen Time And Date From PLC

    Thanks Michael - I do remember that post now LOL. Will have a look - still cannot remember what I did.
  22. Windows 10 and CX-Programmer

    Ha ha! PITA hey?
  23. Windows 10 and CX-Programmer

    Yes - Smart Mode - turn it off and all is good.
  24. CJ2 has long real so does the CP1L.
  25. Time display formatting question

    Thanks for the reply. I will probabaly eventually have to tackle 'the dark side' and just trying to get my head around it a bit. The Schneider M580 is a very different beast to the predecessors as well - still have not got my head around that properly after doing a large job with the redundant processor one. It is all changing I guess.
