LIN command specifies which logic group to be affected. The second number specifies the configuraion. In this

case, the number '10' translates to '01010' in binary. There are zeros in the positions for the first, third, and last

bits -- these correspond to logic inputs 6, 8, and 10 for our case. Similarly, the ones in the second and fourth

positions correspond to bits 7 and 9. The last part of the command specifies the command to be executed with

the pins enter this configuration.

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

F01LIN2,10,MACROX25

Configure logic input group

2 to execute MACROX25

when the pins in logic input

group 2 correspond to the

decimal value 10.

F01LIN2,10,MACROX25

F01LIN1,7,?

Query the command

associated with decimal

configuration 7 on logic

input group 1.

F01LIN1,7,<string> , where <string> corresponds

to the command that is associated with decimal

configuration 7 on logic input group 1.

8.72. 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

F01LIP000000000000000000001111

Set logic inputs 1-20 to

normal (active low) and

logic inputs 21-24 to

inverted (active high).

8.73. 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
