temperature
SC 1 30 mS An Output of Signal
Characterizer block is
a non-linear function of
the respective input. The
function is determined by
a table
IT 1 30 mS Integrator block integrates
a variable as a function of
the time or accumulates
the counts
IS 1 30 mS Input Selector block
provides selection of up to
eight inputs and generate
an output based on the
configured action
AR 1 30 mS Arithmetic block permits
simple use of popular
measurement math
functions
PID 1 45 mS Works as a field PID
controller in conjunction
with other function blocks.
LM Function:
LM function is supported.
LM function is disabled when shipped.
