5 SETTINGS
The summator performs the following operation:
where: X represents the programmed input of summator N (determined by the
S represents the programmed scale of summator N (determined by the
P represents the programmed position of summator N (determined by the
The resulting Y value can be set as absolute or signed, allowing switching between the signed and absolute values of the
summator.
A user-programmable threshold is available to compare the Y value with a constant when driving the output operand:
where: Op is an output FlexLogic™ operand (for example,
D is the user-programmable threshold (for example,
Y is the operating value derived earlier (for example,
The Y value becomes a FlexAnalog parameter itself. As such, it can be used by other summators, FlexElements™, and
user-programmable displays.
The settings for summator 1 are described below. The description applies to all six summators.
•
SUMMATOR 1 FUNCTION: When set to "Enabled", this setting allows summator functionality.
•
SUMMATOR 1 INPUT MODE: This setting how the output data is formatted. When set to "Signed", the sign (positive/
negative) of the input data summation remains intact. When set to "Absolute", the absolute value of the summation is
used as the output value.
•
SUMMATOR 1 HOLD: The output value to the summator is frozen when the FlexLogic™ operand assigned to this set-
ting is active (on).
•
SUMMATOR 1 PICKUP: When the output value of the summator is greater than the value assigned to this setting, the
FlexLogic operand is activated (set to on).
SUMMATOR 1 OP
•
SUMMATOR 1 HYSTERESIS: When the output value of the summator falls below the
value, the
TOR 1 HYSTERESIS
is "1.000" and the
MATOR 1 PICKUP
set to off when the resultant output value falls below 0.970.
•
SUMMATOR 1 UNITS: This setting creates a character label for the summator output value display.
•
SUMMATOR 1 PU BASE: This setting defines the per-unit base factor when using the
alog™ quantity in other N60 features, such as FlexElements™. This value is used to normalize the
FlexAnalog™ quantity (that is, change it to a per-unit quantity). Refer to the FlexElements™ section for additional
PUT
details on per-unit base values.
•
SUMMATOR 1 INPUT1(6): These settings select the FlexAnalog quantity to use as a summator input.
•
SUMMATOR 1 SCALE1(6): These settings apply a scale factor to their corresponding FlexAnalog input quantity as it
is evaluated.
•
SUMMATOR 1 POS1(6): These settings determines if a selected input is used during an evaluation of the summation
process. When the FlexLogic™ operand selected by this setting is activated (set to on), the summator will use the
item multiplied by it's corresponding
MATOR 1 INPUT
•
SUMMATOR 1 EVENTS: This setting is used to generate events for the summator. The
is created on the rising edge of the
