Using Nicknames for the %P References
If you want to use the %P nicknames listed in the table, add them to the Variable
Declaration Table (see page 24).
Global (%G) References for the I/O Link Program Blocks
The %P references listed in the previous table are used for link configuration, control, and monitoring. They will be included in the application program as explained on subsequent pages.
An I/O Link Program Block also uses certain %G references for its own operations. These %G references should not be included in the application program. They should be reserved for the exclusive use of the Program Block.
