Configuring the
Inputs to a Reflex
Block
Every block requires that you configure a set of input values. The block diagram that
appears in the center pane of the reflex editor displays the input fields in a column
on the right (as in item 6 below). The following example shows a two-input AND
block:
This example shows a block with three inputs—an Enable and two operational
inputs (Input 1 and Input 2). Each input has its own pull-down list, from which you
will configure the source of each input. Generally, inputs can be derived from one of
four sources:
from another input module on the island bus
from a constant value that you specify (e.g., always enabled, up-count direction)
from the fieldbus master, in the form of the virtual module (See The Virtual
Module, p. 28) or the action module (See Using the Action Module as an Input to
a Block, p. 32)
