PremierWave® EN Embedded System on Module User Guide

Notes:
To modify a CP, all groups in which it is a member must be disabled.
The changes to a CP configuration are not saved in FLASH. Instead, these CP
settings are used when the CP is added to a CP Group. When the CP Group is
saved, its CP settings are saved with it. Thus, a particular CP may be defined as
"Input" in one group but as "Output" in another. Only one group containing any
particular CP may be enabled at once.
CPM: Groups
The CP Groups settings allow for the management of CP groups. Groups can be created or
deleted. CPs can be added to or removed from groups. A group, based on its state, can trigger
outside events (such as sending email messages). Only an enabled group can be a trigger.
