Automatic reference update for local variables

Renaming a local variable in the
Micro800
 program automatically updates the references to the local variable with the new name. The new variable name must be unique within the
Micro800
 program.
Automatic name changes are reflected in references to local variables in:
  • Ladder diagram Program Organization Units (POU)
  • Function block diagram POUs
  • Structured text POUs
  • User-defined function blocks (UDFB) in POUs
  • User-defined functions (UDF) in POUs
  • Controller configurations
    • Modbus mapping (L20E, L50E, and L70E controllers)
    • MicroLogix mapping (L50E and L70E controllers)
    • DNP3 mapping (2080-L70E-24QBBN and 2080-L70E-24QWBN controllers)
    • Data log (L20E controllers)
    • Recipe (L20E controllers)
After renaming a local variable:
  • References to the variable are updated with the new name.
  • If the local variable is used in a password-protected POU, UDFB, or UDF that is not already open, a message appears stating that it is password-protected.
