Operation
• AND
An AND gate output asserts when ALL of its enabled inputs are asserted.
Disabled inputs are ignored. If only one input is enabled, the logic gate
output copies the input state.
• NAND
A NAND, or Not-AND, gate output asserts except when ALL of its
enabled inputs are asserted. Disabled inputs are ignored. If only one input
is enabled, the logic gate output inverts the input state.
• OR
An OR gate output asserts when ANY of its enabled inputs are asserted.
Disabled inputs are ignored. If only one input is enabled, the logic gate
output copies the input state.
• NOR
A NOR, or Not-OR, gate asserts when NONE of its enabled inputs are
asserted. Disabled inputs are ignored. If only one input is enabled, the logic
gate output inverts the input state.
• XOR
An XOR, or exclusive-OR, gate asserts when only one of its two inputs is
asserted. An XOR gate must have two and only two inputs enabled. Both
inputs must be configured at the same time or an error results.
• XNOR
An XNOR, or exclusive-NOR, gate asserts when either both of its two
inputs are asserted or both are de-asserted. An XNOR gate must have two
and only two inputs enabled. Both inputs must be configured at the same
time or an error results.
In general, a logic gate is disabled and its output is de-asserted if none of its inputs
are enabled. Except for XOR and XNOR gates, any combination of enabled and
disabled inputs is accepted. The output of a logic gate is not permitted to be used
as the input to a logic gate.
Setpoint Setup
The tags listed below configure the operation of each setpoint, and are found in
the
Configuration.Setpoints_1_5 and Configuration.Setpoints_6_10 tables in
the M5 model. The M6 model also has two additional tables for setting up
setpoints 11 thru 15 and 16 thru 20 and a Relative_Setpoint_Interval tag in the
Configuration.PowerQuality table for configuring the sliding reference for all
setpoints..
Parameter Selection n
Selects a power monitor parameter to track. See Setpoint Parameter Selection
List on page 164 .
