CHAPTER 5: SETTINGS
Six identical summators are available in each N60 device.
Each summator has six inputs and a scaling factor is provided for each input. The scaling factors can be set to +1 and –1,
allowing straight addition and subtraction of the inputs. A FlexLogic operand provided for each input can dynamically
include/exclude the input from calculations.
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 as follows. The descriptions apply to all six summators.
— When set to "Enabled," this setting allows summator functionality.
SUMMATOR 1 FUNCTION
— Determines how the output data is formatted. When set to "Signed," the sign (positive/
SUMMATOR 1 INPUT MODE
negative) of the input data summation remains intact. When set to "Absolute," the absolute value of the summation is used
as the output value.
— The output value to the summator is frozen when the FlexLogic operand assigned to this setting is
SUMMATOR 1 HOLD
active (on).
— When the output value of the summator is greater than the value assigned to this setting, the
SUMMATOR 1 PICKUP
FlexLogic operand is activated (set to on).
