Micromod Micro-DCI: 53MC5000 Multi-Loop Process Controller Installation - Manual (Page 74)

4.1.3 CS 1 STANDARD PID FCS DISPLAYS
The 53MC5000’s dot matrix display provides unequalled capability for presentation of information
to the user. The default CS1 FCS configuration includes five displays as described below. The user
can easily incorporate additional displays if desired as described in Section 4.2 of the Instruction
Bulletin 53MC5000 .
The standard display list includes:
•
Single Loop Display (CON0) - The loop 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).
•
Single Loop with Trend display (CON0) - This display provides digital indication of
the PV, SP and OP associated with the loop, but adds a 40-value process variable
trend. The sample rate of the trend is defaulted every 2 seconds. Sample rate may
be changed by setting B336 equal to the desired sample rate in seconds.
Acceptable values of B336 are 0, 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, and 60
seconds. Any other value will be reduced to the closest of these values.
•
Parameter display (PID parameters - Displays the tuning parameters for the loop;
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 al-
phanumerics.
3. When the number on the screen is correct, press F3 to enter the number.
•
Parameter display (Alarm limits) - Displays the alarm parameters for the loop;
Alarm Limit #1 (HI), Alarm Limit #2 (LO), and the Alarm Deadband. Values may be
changed as described above.
•
System status - This 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).
