    4 position control axes... position control axes are basic motion axes, and do not support group motions.  The instruction set in the manual shows which instructions can be used on a single axis positioning axis.

    The HMI already has a security system and if someone attempts to access a page that has security, it will prompt for a user name and password automatically.

    You need to set security for a page, and then create the users and assign them the proper security levels.

    I have a Schneider Electric M258 with no lights on the CPU. I have verified that I have power going to it. I also have a spare unit that I removed from another location because I only got red lights on that one. I put this one it and I did get lights although they were all still red. I did that to verify that I did have power going to the CPU. Is there something that you know that I can check? Does anyone repair this model? I understand that it is now obsolete.

     

    Thanks all,

    If it has no lights at all, likely something has failed internally.  Most PLCs have at least a power LED that should be on.  Not familiar with that unit, but doesn't sound good...

    Not sure what you meant by 'the 10 input'.  But that's 2 digits. 

    BCD is 0-9 only.  So each group of 4 inputs MUST make a valid number 0-9.  K5X460 means 5 digits, X460-463, X464-467, X468-X46B, X46C-X46F, and X470-473

    0001 through 1001

    If for example your inputs are 1010, that's 10,  that's not legal for a single digit of BCD.

    Make sure the data on those 2 inputs makes 5 valid BCD values.

    I find it interesting that it is possible to do a function like this 

    It's a programmable controller, you can program it to do anything you like. Every controller out there can do it, not just these...  Even a PC, it's all in the code you write...

    I've been asked to write exactly the same thing one, and I refused.

    4100 is a generic operation error... in your case it has nothing to do with a memory card or a network...

    Look at the FIRST line of the error message... THE INSTRUCTION CANNOT PROCESS THE CONTAINED DATA.  When it gives you a program name and step number, it's a program error.

    The instruction it is highlighting is having an error with the input data... so what is put in via K4X460 does not work in the DBIN instruction... check the status of your inputs starting at X460 and see what it is trying to do.  And look at the help for DBIN to see what about it can cause the 4100 error.

    Thanks for the responses.
    Definitely puts a hurdle on development time/development consistency for Sysmac Studio projects where there's large portions of device replication, meaning we're unlikely to recommend them to any end users asking for advice. 

    A lot of copy/paste looks to be the solution for this current jobs requirement though.




     

    There are options in Studio that allow you to inherit information from one project to another.  I personally have never used them, but that should allow you to make a master project and then make new projects by selecting parts of that master project.  I asked around, nobody has ever heard of an EXPORT function for XML, only the IMPORT from the IEC XML type.

    the only thing annoying is that you cannot see the status of coils and contacts from the buffer memory in monitoring mode.
    I wonder when Mitsubishi will fix this "problem".
    Is this still the case with the Q, L and IQ-R systems?

    GX Works2 and GX Works3 both had means to monitor buffer memory.  Haven't touched either in a number of years, so I forget the actual name of the window.

    Global variables only.

    When you make the HMI variable on the Variable Mapping screen, it inherits the data format of the PLC variable.  Make sure you go to the Variable Mapping tab in the HMI project and map an HMI variable to the controller variables.  The HMI is a separate device, and has its own variable table.

    Also check that you added your program to a task in Task Settings.  When you add new programs to a project (as you must have, since the default is a ladder program) you must go into Task Settings and assign it to a task like the primary task so that it executes.  The software doesn't assign them automatically.

    The media's sole purpose is to sensationalize and scare.  Years ago, back when people like Walter Kronkite were alive, they reported the news.  Now everyone has to be the first to report even if they have nothing to report, and they are all about giving each other awards.  They have no reason whatsoever to actually give truth anymore.  And if they do get caught, the retraction is done so quietly that nobody sees it, so the lie persists.

    And the sheeple believe every word of it, without even so much as a fact check.

    The Tesla issue is 100% verifiable human error.  Someone did not follow proper lock out tag out procedures.  Safety systems are designed to prevent these types of accidents, but some people just do not follow directions.  No robots attacked anything.  But that doesn't make the news media any advertising revenue.  And let's face it, if it was anywhere other than Tesla we wouldn't hear about it...

    Has any configured a remote ethernet rack using the CJ Platform?
    Scenario:
    Local Rack: PSU + PLC + Ethernet Card
    Remote Rack: PSU + Ethernet Card + IO...
    Then using network configurator, I make an input output map for the remote rack. To send and receive the data from the remote rack.
     
    I have found this link which I think relates to my question, But I just want to see if any out there has done it and has some more detail, to another doc that they can link.
     
    The final stage would be to set us up to migrate to the NJ platform when the time comes using the existing IO.

    There has never been a remote rack solution for Ethernet on the CJ Series.  You cannot simply slot an Ethernet module into a rack and expect it to control the rack.  Rack control is the job of the CPU.  Closest you can come would be get another low end CJ CPU for that remote.
