Glossary 3
output image - The output from the SLC processor to the 1746-NI16
module. The output image contains the module configuration
information. Each output word configures a single channel.
remote configuration - A control system where the chassis can be
located several thousand feet from the processor chassis. Chassis
communication is via the 1747–SN Scanner and 1747-ASB Remote I/O
Adapter.
resolution - The smallest detectable change in a measurement,
typically expressed in engineering units (e.g. 1 mV) or as a number of
bits. For example a 12–bit system has 4,096 possible output states. It
can, therefore, measure 1 part in 4096.
scaling - The process of changing a quantity from one notation to
another.
status word - Contains status information about the channel’s current
configuration and operational state. You can use this information in
your ladder program to determine whether the channel data word is
valid.
step response time - This is the time required for the channel data
word signal to reach a specified percentage of its expected final value,
given a large step change in the input signal.
transducer - A device that converts one energy form to another (e.g.,
mechanical to electrical). When a transducer is actuated by signals
from one system or medium, it can supply a related signal to the other
system or medium.
