Physical Output The block produces as its output a Boolean 1 when the input value is less than
threshold - ∆ and a Boolean 0 when the input is greater than or equal to
threshold + ∆. 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 block. Specify the channel as None.
When the output of 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.
