T01LIN2,10,MACROX25
Configure logic input
group 2 to execute
MACROX25 when the
pins in logic input group
2 correspond to the
decimal value 10.
T01LIN2,10,MACROX25
T01LIN1,7,?
Query the command
associated with decimal
configuration 7 on logic
input group 1.
T01LIN1,7,<string>, where <string>
corresponds to the command that is associated
with decimal configuration 7 on logic input group
1.
8.51. LIP -- Set Polarity for Logic Inputs
This command sets the polarity for the 24 logic input pins. Setting the polarity for a given pin to 0
indicates that the polarity should be normal (active low). Setting the polarity for a given pin to 1
indicates that the polarity should be inverted (active high). Active low is considered normal because a
closed switch would ground the input, and a closed switch would normally be considered active.
This command affects the operation of the
LIA, LID, and LIH commands. If a logic input pin's polarity
is reversed, the operation of these commands is reversed.
By default, the polarity for all pins is set to normal (active low).
This command is saved to global non-volatile memory and is not part of a preset. Its value is saved
each time it is changed. It will retain its value after power-down. Since this command writes to non-
volatile memory, there will be a delay before an acknowledgment is returned.
Example Description Status Message
T01LIP000000000000000000001111
Set logic inputs 1-
20 to normal
(active low) and
logic inputs 21-24
to inverted (active
high).

8.52. LO -- Query or Set Status of Logic Output Pins
This command sets or queries the current state of the logic outputs. There are 20 logic outputs, so an
array of 20 boolean values is required or returned, with the first value indicating the state of the first
logic output, the second value indicating the state of the second logic output, and so on.
If a logic output pin has conditions driving it (via the
LOA and LOD commands), those conditions will
override any settings imposed by the LO command.
If a logic pin is masked via the
LOM command, its status will still be affected by the LO command.
