F01LIA7,

Assign a blank command to

occur when logic input pin 7

changes from the inactive

state to the active state.

Assigning a blank command

means no action will take

place as a result of this state

change.

F01LIA7,

F01LIA4,?

Query the command

associated with the active

state of logic pin 4.

F01LIA4,<string> , where <string> is

the command string that will be executed

when logic input 4 is activated. If this query

was given after the example for logic input 4

above, the response would be

F01LIA4,MUTEI11 .

8.65. LID -- Assign Action for when Logic Input is Deactivated

This function assigns a single command to be executed when a given logic input changes from the active state to

the inactive state. Typically, the inactive state is logic high ('1') and the active state is logic low ('0'). This is

commonly referred to as active low. Acitve low is considered normal because a closed switch would ground the

input and a closed switch would normally be considered active. This polarity setting can be changed via the

LIP

command.

A single command can be assigned to each of three conditions occurring on the logic pin: a change to the active

state, a change to the inactive state, and a repeating command when the pin is held in the active state. The LID

command assigns a single command to the logic pin that is executed when the logic pin changes to the inactive

state.

Although only one command can be assigned to the state change, the command may be a

MACROX or MACROQ

command. Since up to 256 commands can be stored in each macro, this gives the effect of having up to 256

commands execute when the logic pin changes state. The command associated with the state change can also

be a

PRESETX or PRESETQ. This makes it easy to reconfigure the device for different rooms based on external

logic settings.

The

BROADA is also useful in logic pin assignments. The BROADA command transmits a command to another

device on the EF Bus, so you can effectively make a logic pin state change on one device cause an action to

occur on another device.

ERROR#074 will be generated if the assigned command is one that writes non-volatile memory, and the pin will

not actually be assigned.

See the description of the

LIA for examples on how to use the LID command. The syntax for this command is

exactly the same.

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.

8.66. LIH -- Assign Action for when Logic Input is Held

This function assigns a single command to be executed repeatedly when a given logic input is held in the active
