9.0 LOCAL FACEPLATE OPERATION
Controller operation is described in this section. Each faceplate display, pushbutton, and knob will be discussed
first in normal operation mode and then in configuration mode. This section contains many references to function
blocks. As necessary, refer to Section 3 for details about a function block.
Most operator controls are shown on the faceplate below. Several additional pushbuttons are located behind the
flip-down door at the bottom of the faceplate. These will be discussed in the configuration mode portion of this
section.
9.1 NORMAL OPERATION MODE
•
6-Digit Numeric Display - displays the numeric value of the variable
identified by the 8-character alphanumeric display. Numbers can be
displayed from 0.00000 to 999999 or -0.0000 to -99999. Any input
exceeding these limits will be shown as the maximum or minimum
displayable value and cause the display to flash.
•
8-Character Alphanumeric Display - normally displays the loop tag with
the dot suffix of the variable currently showing in the 6-digit numeric
display (e.g. TC2053.P is the Process variable for loop TC2053). A loop
tag that is displayed is called the Active Loop and all operator controls
(e.g. PB1, PB2, A/M, ACK, D, UNITS, ALARM, TUNE, TAG, QUICK)
will affect the function blocks within the Active Loop.
•
PB1 Pushbutton - controls the operation of the PB1SW (PB 1 transfer
SWitch) function block when the block has been configured for use
within the Active Loop. See the function block details in Section 3 for
more information on PB1SW.
•
PB2 Pushbutton - controls the operation of the PB2SW (PB 2 transfer
SWitch) function block when the block has been configured for use
within the Active Loop. See the function block details for more
information on PB2SW.
•
A/M Pushbutton - controls the operation of an A/M (Auto/Manual)
function block when the block has been configured for use within the
Active Loop. See the function block details for more information on
A/M. When the A/M is switched to Auto the numeric display will show
the Setpoint value, as indicated by .S in the alphanumeric display, and
when switched to Manual, the Valve value and .V will be shown.
•
LOOP Pushbutton - One or more loops can be configured. When more than one loop has been configured, the
LOOP button will advance the operator display to the next Active Loop. All operator controls now affect the
Active Loop that is currently shown in the alphanumeric display (e.g. FC2367). When a loop is first displayed,
the loop tag will appear in the alphanumeric and the displayed variable will be the same as when the loop was
last viewed.
•
ACK Pushbutton - this button is used together with the L and S status LEDs to manage events (e.g. alarm,
status, and error conditions) within the controller. Events have user assigned priorities 1-5 (with 1 the highest)
and will be organized within the controller, first by priority and then by order of occurrence.
•
S Status LED - Indicates that event is active in the Station. A flashing LED indicates that the event needs
to be acknowledged.
•
L Status LED - Indicates that event is active in the displayed Loop. A flashing LED indicates that the event
needs to be acknowledged.
