Glossary
resolution – The smallest detectable change in a measurement,
typically expressed in engineering units (for example, 1 mV) or as a
number of bits. For example a 12-bit system has 4096 possible output
states. It can therefore measure 1 part in 4096.
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 – For inputs, 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.
update time – See module update time.
