Result of a Reflex
Block Depending on the type of reflex block that you use, it will output either a Boolean or
a word as its result. Generally, the result is mapped to an action module, as shown
in the following table:
The result from a block is usually mapped to an individual channel on an output
module. Depending on the type of result that the block produces, this action module
may be an analog channel or a digital channel.
When the result is mapped to a digital or analog output channel, that channel
becomes dedicated to the reflex action and can no longer use data from the fieldbus
master to update its field device.
The exception is when a reflex block is the first of two actions in a nested reflex
action.
Reflex Action Result Action Module Type
Boolean logic Boolean value digital output
integer compare Boolean value digital output
counter 16-bit word first block in a nested reflex action
timer Boolean value digital output
digital latch Boolean value digital output
analog latch 16-bit word analog output
