Background
Scan Index
This parameter directs how often the display is renewed and when activated with Background
Program (BACK - B008), the period for executing the EASY-TUNE algorithm. The period
realized equals
B006 X B003 X 50 mS
.
BSCAN B006 1
Background
Overrun
Counter
This parameter is incremented whenever the execution time of the display program and
background program exceed the repetition rate realized by SCAN X BSCAN. Each time an
increment occurs, one pass of the display update and background program is skipped. In order
to stop overruns, increase the value of the Scan Index (SCAN - B003) or the Background Scan
Index (BSCAN - B006).
BOVR B007 0
Power-Up
Status
This datapoint is forced to 1 whenever a unit power-up sequence is initiated. If the value is
cleared to 0, it may be monitored to detect unexpected power cycling or restart activity.
PWRUP L066 0
Link List
Load
This parameter loads the Control Strategy Wirelists. Configuring this value forces the FIX to
0
and installs the selected wirelist and any associated database changes, then returns the value
to
0
. If a non-existent control strategy is selected, the default wirelist is loaded.
LLD B016 0
Model
Number Low
This datapoint contains the first 10 characters of the controller model number. A190
Model
Number High
This datapoint contains the remaining controller model number characters starting from the
eleventh character.
A191
Unit
Identifier
This parameter contains the unique identifier code assigned to the unit. The value is obtained
from hardware.
UID A318
License Key
This atom contains the key code to activate functionality. The value is initially assigned at the
factory.Upgrade keys may be loaded in the field.
LKEY A319
Process
Control
Station
This atom indicates which processor controller hardware is attached. It is assigned by internal
code and must not be overwritten.
0 - Standard
1 - Enhanced
PCS B093
Display
Type
This atom indicates which display hardware is attached. It is assigned an internal code and must
not be overwritten.
0 - Standard Display [48 x 96]
1 - HiRes Display [96 x 192
