module; otherwise, they will not appear in the
oPEr prompt list.
7. Discrete output logic blocks (Logic 3 and 4) -
p a r a m e t e r i n p u t s t o b o t h l o g i c m o d u l e s
(LG3.A, LG3.b, LG3.A, and LG3.b) have the
same parameter prompt list selections ([1] -
LG2). The outputs of both logic modules can
be accessed by the do1.i - do8.i parameters of
the discrete output registers 1 - 8 (DO1 - DO8).
8. Analog Outputs (AO1-3) - the one analog out-
put associated with the standard hardware is
shown at Ao1. The input prompt list (nc - dV)
is identical for the Ao1.i - Ao3.i parameters of
the analog output registers 1 - 3 (AO1 - AO3).
Values in analog output registers AO2 and
AO3 can be looped-back to the math function
block and/or control scheme block.
Notice, that the input prompt list includes Ai1 -
Ai8 path connections for analog input re-trans-
mission.
9. Discrete Outputs (DO0-8) - digital outputs as-
sociated with the standard and optional hard-
ware are shown as DO1, DO2, DO3, and DO4,
respectively. The input prompt list (nc - LG4)
is identical for the do1.i - do8.i parameters of
the digital output registers (DO1 - DO8). Val-
ues in discrete output registers DO7 and DO8
can be looped-back into the characterizer and
math function block digital inputs. Only the
DO8 value can be looped-back into logic
blocks 1 and 2 (LG1 and LG2).
Notice, that the input prompt list (nc - LG4)
does not include any discrete input path con-
nections; therefore, to re-transmit a discrete
input logic condition, it must first pass through
one of the input logic modules (LG1 or LG2)
which is connected to a discrete output 1-4.
For example, to connect DI1 to LG1 and LG1 to
DO1:
•
LG1.M = A OR B
•
LG1.A = di1 (connects DI1 to LG1 input)
•
LG1.b = 0 (so any input on LG1.A is
passed through unaltered)
•
do1.i = LG1 (connects DO1 to LG1)
NOTE: Many different process control strategies
can be implemented through the interconnecting
path variations, the five control schemes, and the
large array of configuration prompt selections that
are available in the 53SL6000 controller.
However, to expedite configuration, the eight
control strategies mentioned in Section 1 can each
be invoked very quickly by using the factory
parameter default values and one of the
ProG-cS-SchM parameter selections (for example,
the factory default values and the cASc prompt
from the SchM menu selects Single Station
Cascade Control operation with dual PID control).
These eight control strategies are covered in
Section 8.
