Accessing the Reflex Editor
Overview The reflex editor allows you to configure reflex actions in your island configuration.
Reflex actions are small routines that execute dedicated functions directly on the
island bus. These actions allow output modules on the island bus to act on data and
drive field actuators directly, without requiring the intervention of the fieldbus master.
A typical reflex action might be:
a Boolean AND or exclusive OR operation
a comparison of an analog input value to a user-specified threshold value
an up- or down-counter operation
A timer operation
the triggering of a latch to hold a digital value high or low
the triggering of a latch to hold an analog value at a specific value
An island configuration can support up to ten reflex actions.
Procedure The reflex editor can be accessed by either:
clicking the button
selecting the Reflex Editor command from the Island pull-down menu.
