  • Create global variables and change their attributes.
  • Change the following attributes of global variables that are added before entering RMC:
    • Comments
    • Alias
    • Retained
  • Change or remove local variables that are not referenced by
    Micro800
     controller configuration.
  • Delete or change the following attributes of local variables that are referenced by
    Micro800
     controller configuration:
    • Comments
    • Alias
    • Retained
  • Create, change or remove defined words.
  • Export global and local variables.
  • Delete or change the attributes of local variables that are referenced by
    Micro800
     controller configuration, excluding
    Comments
    ,
    Alias
    , and
    Retained
    .
  • Delete existing global variables.
  • Change variable attributes or add or delete variables in a user-defined function block (UDFB) that is referenced by a global variable.
  • Create, remove, or change the attributes of user-defined arrays and structures, excluding
    Comments
    .
  • Change or remove the project value of variables.
  • Change the data type of dimensional variables.
Projects and POUs
  • Change logic in Program Organization Units (POUs).
  • Copy/paste POUs within or between sessions.
  • Rename or delete POUs whose variables are not referenced by
    Micro800
     controller configuration.
  • Reset initial values of UDFB instances.
  • Synchronize updates to references from UDFBs or UDFs.
  • Save or export projects.
  • Change the order of POUs in
    Project Organizer
    .
  • In the
    Parameter

  • RMC changes that add comments to arrays or structures not referenced by the
    Micro800
     controller configuration cannot be downloaded to the controller.
  • After changing the project value of global or local variables in RMC mode, when reconnecting to the controller, you cannot enter RMC mode again.
