Integer Compares

Physical Output The block produces a Boolean 1 when the input value is outside the window and a
Boolean 0 when the input value is not outside that window. The physical output (See
Configuring the Physical Output from a Reflex Block, p. 27) needs to be mapped to
an action module:
The action module may be a digital output module on the island bus. In this case,
you need to specify one of the digital output channels as the destination for the
reflex output.
If the compare is the first block in a nested reflex action (See Nesting Two Reflex
Blocks, p. 36), the action module needs to be the same action module as the one
specified for the second reflex block. Specify the channel as None.
When the output from a block is mapped to a channel on a digital output module,
that channel becomes dedicated to the reflex action and can no longer use data from
the fieldbus master to update its field device. The fieldbus master still has the ability
to write data to this bit address in the NIM, and the reflex action editor lets you use
this data from the fieldbus master as an input to the block.
