8–2 MM300 MOTOR MANAGEMENT SYSTEM – INSTRUCTION MANUAL
FLEXLOGIC™ OVERVIEW CHAPTER 8: FLEXLOGIC™
Each timer may only be used once within any given starter.
A maximum of thirty (30) one-shots are allowed.
512 lines are executed during every 50 ms.
The operators available in FlexLogic™ are shown below.
Table 1: FlexLogic™ operators
The FlexLogic™ operands available in the MM300 are listed below.
Control operands: auto/manual
Auto...............................................Asserted when auto mode is enabled.
Comms Ctrl Actv .....................Asserted when the communication start controls have all
required supervision enabled.
Field Ctrl Actv............................Asserted when the field start controls have all required
supervision enabled.
Field Trip......................................Asserted when a trip resulting from a field control contact input
has yet to be reset.
Hard Wired Ctrl Actv..............Asserted when the hard-wired start controls have all required
supervision enabled.
Hard Wired Trip .......................Asserted when a trip resulting from a hard-wired control
contact input has yet to be reset.
Manual.........................................Asserted when manual mode is enabled.
MCC Ctrl Actv............................Asserted when motor control center (MCC) start controls have
all required supervision enabled.
MCC Trip......................................Asserted when a trip resulting from a motor control center
(MCC) stop has yet to be reset.
Operator Inputs Description
<operand> none The output value is the value of the named <operand>.
NOT 1 The output value is “on” if and only if the intput value is “off”.
OR 2 to 16 The output value is “on” if and only if any of the input values are
“on”.
AND 2 to 16 The output value is “on” if and only if all of the input values are
“on”.
NOR 2 to 16 The output value is “on” if and only if all of the input values are
“off”.
NAND 2 to 16 The output value is “on” if and only if any of the inputs values are
“off”.
XOR 2 The output value is “on” if and only if one input value is “on” and
the other input value is “off”.
TIMER 1 The output value is “on” if the input value has been “on” for the set
pickup time. Once the output value is “on”, it remains “on” until the
input value has been “off” for the set dropout time.
LATCH 2 The output value is the state of a reset-dominant volatile bi-stable
latch, where the first input value is the set input, and the second
input value is the reset input.
Positive one-shot 1 The output value is “on” for one processing cycle following an off-
to-on transition of the input value.
Negative one-shot 1 The output value is “on” for one processing cycle following an on-
to-off transition of the input value.
Dual one-shot 1 The output value is “on” for one processing cycle following either
an on-to-off or off-to-on transition of the input value.
ASSIGN <operand> 1 The input value is assigned to the named operand. There is
otherwise no output value.
END none The first END encountered terminates the current processing
cycle.
