Faceplate The entire visable front of the
controller casework that con-
tains the push buttons and
LEDs.
Final
Control
Element The actual device used to al-
ter the process medium (e.g.,
flow, heat, gas density, etc.)
level under control.
Integral
Action (tr) Integral action (tr) produces a
value that is a function of the
deviation from setpoint and
the %PB setting. It augments
proportional action to drive
the process final control ele-
ment until the deviation is
nulled. Integral action is set
as the time between repitition
i n t e r v a l s f r o m 0 . 0 2 m i n-
utes/repeat (maximum action)
to 200 minutes/repeat (mini-
mum action); 0 is off.
Light
Emitting
Diode
(LED) A diode that emits photon en-
ergy in response to electrical
impulses. In the 53SL6000
contr oller, an LED can be
used as an indicator, in which
case it appears on the display
as a single light point source
(e.g., the "1" LED on the dis-
p la y t ha t i nd ic at es loop 1
when active); or LEDs can be
grouped together for a spe-
cific function (e.g., each char-
acter position of a dro has
seven LEDs that are available
to create the displayed char-
acter and one LED for the
decimal point).
Logic
Block A logic block can perform any
one of eight Boolean func-
tions on two inputs. The func-
tions are: A OR B, A AND B,
A XOR B, A OR NOT B, A
AND NOT B, NOT A OR B,
NOT A AND B, and NOT A
XOR B. There are four logic
blocks in the 53SL6000 con-
troller as part of the discrete
input/output decision path.
As determined by path con-
nection capabilities, two of
the logic blocks are primarily
for the discrete inputs (DIs)
and two are for the discrete
outputs (DOs). The discrete
output logic blocks can be
connected with path selec-
tions to accept logic decisions
from the discrete input logic
blocks.
Loop
Control
with
Remote
Setpoint A control strategy whereby a
continuous analog output sig-
nal or discrete output logic
signals are calculated based
on the difference between a
process variable input and a
setpoint. The setpoint can be
set locally or received from a
remote source. This control
strategy is implemented in the
53SL6000 controller with the
factory default settings and
by selecting the SnGL prompt
for the Pr oG- cS- SchM pa-
rameter.
Math Function
Block The math function block pro-
vides nine different equations
capable of computing from a
maximum of six Fnc parame-
ter constants (K 1-K 6) and
four analog inputs (A-D) to
produce an augmented ana-
log output. A logic output is
also provided as a state indi-
cator for the limiter equations.
It can also accept two logic
inputs to choose any one of
four selector equations.
Menu One of three prompts: oPEr,
conF, and ProG that can be
invoked on the display in en-
g i n e e r m o d e . T h e o P E r
menu provides operator ac-
cess to commonly used pa-
rameters that must first be
enabled from the conF-oPr
module. The conF and ProG
menus each provide a suite of
modules that contain parame-
ters used to configure control-
ler operation.
Module An optional unit (e.g, RS-232
module) that can be installed
at the rear of the 53SL6000
controller case.
