4.2.3 CS 20 STANDARD PID FCS DISPLAYS

The 53MC5000’s dot matrix display provides unequalled capability for presentation of information
to the user. The default CS20 FCS configuration includes ten displays as described below. The
user can easily incorporate additional displays if desired as described in the Instruction Bulletin
53MC5000.

The standard display list includes:

Two Loop Overview display - This display provides an overview of both loops. The
PV’s are displayed in bargraph form with a SP arrow. The Output (OP) is shown as
a horizontal bargraph. The tags of both loops are shown at the top of the screen.

Two Single Loop Displays (CON0 and CON1) - An individual display is provided for
each loop. The PV is displayed in digital and bargraph form (in engineering units)
with a SP arrow. Alarm limits are displayed as ticks on the PV. When in alarm
condition, the alarm line will flash. The PV bargraph is displayed with a scale
including the minimum and maximum range values. The OP is shown as a
horizontal bargraph with a digital display of output percent. Auto/Manual and
Remote/Local mode indications are displayed at the bottom of the screen.

Two Single Loop with Trend displays (CON0 and CON1) - An individual display is
provided for each loop. This display provides digital indication of the PV, SP and
OP associated with each loop, but adds a 40-value, process variable trend. The
sample rate of the trend is defaulted at 2 seconds. Sample rate may be changed by
setting B336 equal to the desired sample rate in seconds.

Two PID Parameter Display - An individual display is provided for each loop which
displays the tuning parameters; Proportional Band, Reset Time, and Derivative
time. Values may be changed by an operator as follows:

1. Use the Up/Down (SP) arrows to position the cursor at the value to be
changed. Press F3 to select.

2. Use the Increase/Decrease (OP) arrows to move the value to the digit to
be changed. Use the Up/Down (SP) arrows to page through the list of
alphanumerics.

3. When the number on the screen is correct, press F3 to enter the number.

Two Alarm Limits Parameter displays - An individual display is provided for each
loop which displays the alarm parameters; Alarm Limit #1 (HI), Alarm Limit #2 (LO),
and the Alarm Deadband.

Values may be changed as described above.

System status - Displays the control strategy (FCS=1), the control strategy scan
rate (3 = 150 ms), control strategy overruns, the display scan rate (1 = same as
Control Strategy Scan Rate), the display overruns, and the instrument address (0).
