  1. 2 PV800s controlling one PLC

    One HMI is commanding the bit to be OFF and the other HMI is commanding the same bit to be ON. The general convention would be to use two separate bits. One bit for the Push Button (Value) and one for the Indication (Indicator). Further more, you may want to perform your 'Maintained' condition in the PLC.
  2. Error on the Rung - Quick Question

    This is one of the less intuitive functions in CX Programmer. Place the cursor as shown in the picture below then perform Insert > Function Block Parameter.  
  3. Starting with Omron CX-P

    You can change the Program Check Options under the PLC menu.
  4. Keyence plc's

    KV series PLC's are not supported in the US. They do have English software. Download KV Studio Trial Version from their website. If the PLC is very old then you may have to contact your local Keyence representative and ask them for a copy of Ladder Builder.
  5. unknown text

    I'm not aware of any setting in CX Programmer for language. I had this problem with Japanese text. If you have the language installed on your PC then you can export the comments and change them in MS Excel.
  6. Starting with Omron CX-P

    This is correct. Siemens precedes a memory location with the data type. Omron precedes it with the type of memory. 'CIO' will be the physical I/O. Anything out of range of the physical I/O may be freely used. 'A' memory is generally used for system memory. (Always ON, Clock Pulses, instruction feedback, etc...) 'W' memory is yours. This is what you may freely use for most of your programming. 'D' is retentive. Generally used in WORDS. (INT, DINT, REAL, etc...) 'H' is retentive. Generally used as bits. May be used as WORDS. 'E' is retentive. It extends 'D'. The amount will be determined by the CPU type you purchase.    I believe the manuals that come installed are pretty good. When I'm programming, I tend to right click on an instruction and choose 'Instruction Help'.
  7. Can not set a password

    Can you post a screen shot?
  8. Hi There IO_Rack i need your help here

    i have one c200hw-mc402-e and i try to connect with a cs1w-cpu44h i cant realise how connect this 2 .

    can you please write one sinple plrogram to connect the cpu and this card becouse i try to connect with motion perfect and i cant connect the card have 2 Flashing liths the run and disable.

    One of the following errors occurred in the configuration of MC Unit and CPU Unit: Illegal unit number Unit number duplication Cyclic initial error Unit number setting error
    the unit is 0 is the a way to remove the program from the unit

  9. Connection with a CPM2A PLC

    I was unaware of the Chinese model "E". Did you try the Auto Online > Direct Online feature in CX Programmer using the CIF01 cable? Is the HMI an Omron? If so, it's possible the 9 pin port may be set to NT Link and you will not be able to connect CX Programmer.  
  10. Connection with a CPM2A PLC

    This is referring to the 9 Pin port. Did you try this? Be sure to find the correct cable. The HMI cable will not work with CX Programmer.
  11. In the PLC Settings, there is a Startup tab where you can change the Mode the PLC will start with.
  12. Retained tags

    There are many ways. It depends on your application. Typically a retained tag will be a variable setting for your application. Example would be a speed setting for a VFD or a temperature setting. Typically they would be written to from an HMI. If the 'Initial Value' field is blank and there is no PLC code writing to this variable then the last setting value will be retained after power loss.
  13. Multiple word values in a union?

    If you don't want them to affect each other then create a Structure containing Union A and Union B. A Union is specifically designed to share the same memory locations.
  14. Can't modify memory

    The Transfer To PLC and Transfer From PLC are Offline (Monitor OFF) functions. If you are Online and write a 0 in the box, then you have already written to that memory location in real time. Be sure to save all your memory first.  
  15. Double check Motoman's definition of Input and Output instance values. Generally the Inputs and Outputs are referred to from the Master's (NX) perspective. If this is the case then you have them reversed.
