Appendix 1. Function Block Parameters
NOTE: Throughout the following tables, the Write column shows the modes in which the respective
parameters can be written. The legends of the entries are as follows:
O/S: Can be written when the corresponding block is in O/S mode.
Man: Can be written when the corresponding block is in Man mode.
Auto: Can be written when the corresponding block is in Auto, Man, or O/S mode.
— : Can be written in no mode of the corresponding block.
Blank: Can be written in all modes of the corresponding block.

the point from which an alert is issued; normally
used by an upper-level system to select alerts
to provide to a particular operator who covers a
specific area of the plant.
