Sample Structure for MCH72 Unit


Introduction
 


CJ2 Family PLC's support Structure data types which can be used to access the data areas in SIO units like the MCH72


Using the structure


To use this structure in a program:

  1. Open the attachment. When using Notepad, turn off "Word Wrap"
     
  2. Copy the whole structure to the clipboard
     
  3. Paste into CX-Programmer's Data Type window (Note this is only available for CJ2 PLCs)
     
  4. Open the IO Table and add the MCH72 unit with the correct Unit address
     
  5. Note the SIOU address in the square brackets (e.g. [1500])
     
  6. Create a new Global Symbol, of type STRUCT MCH72COMMON and set the physical address (e.g. to 1500)
     
  7. The member variables of your new symbol can now be used in your programs to access the SIOU setup area
