    What cable do you have connected from your USB-Serial adapter to the PLC?

    You cannot connect directly to the PLC serial port. You'll need a Host Link cable. You can make this yourself.

    I only use direct converter cable. PC > USB-Serial Cable > PLC

    How do I get the pinout for this Host Link Cable?

    If the processor has a good battery, it will last as long as the battery.

    If no battery, it should last as long as the power supply capacitors hold a charge, typically about 5 minutes.

    So with good condition battery, how long in weeks or days?

    Hi,

     

    I have a self-bought usb-serial cable converter for CP1E. Currently can't connect to my PLC using PC.

    CX-One says "Failed to the PLC". I am supposedly to use "SYSMAC WAY" as my Network Type in PLC settings?  

    EDIT: The CPU type is N30

     

    I've checked the following settings:

    1) COM number is correct ( as checked from windows Device Manager side)

    2) Cable driver is installed, there is no "unknown" driver in my windows Device Manager

    3) My RS232C LED in PLC is not lighted up.

     

    Any other suggestions to check settings ive missed out would help, other than buying a new cable for the moment.

     

    Regards,

    The memory card is a compact flash card.

    You would need to transfer information to the card to save it.

    The CJ2M has a battery for program retention and certain memory areas are retained when the power is off.

    Battery life mostly depends on the ambient temperature.

    Hope this helps.

    Thanks for the respond,

     

    How long will the retained memory last if no power supplied to the PLC?

    Hi All,

    Just to verify if the "memory card" , in attached document Page 4 highlighted area ,  provides Omron CJ2M CPU21 to retain memory when powered off? If yes, for how long can the memory lasts without being charged? Isit capacitor or battery? Thanks in advance.

    Regards,

    Hello,

    I have a cp1h-y20dt-d (sinking output) plc supposedly to be wired to a servo controller. The pulse control method is Pulse/Direction. I've did some manual research on the PLC and found the following diagram attached Untitled.

    Since the diagram above doesnt show which terminals does it connect to in the CP1H side circled red, I want to ask if those connections belong to the following diagram attached Untitled1?

    If so, assuming im planning to use only Pulse Output1 (Pulse/Direction method) from the PLC side, is the connection from the first diagram no.1=CCW0- , no.2=CCW1- , no.3=COM (connected to -ve)

    *Note: these diagrams are from omron's manual SYSMAC CP Series CP1H-X40D_-_ CP1H-XA40D_-_ CP1H-Y20DT-D CP1H CPU Unit

    Your replies would greatly help.

    Thanks and best regards,
    Summer

    Hi! 

    I'm new and was wondering if anyone here has experience on Festo's PLC? I'm looking for recommendations and guides to start using their software. Any help will do.

    Thanks,
