8.87. LOD -- Define Behavior for Logic Output Deactivated
Status
This command is used to define the conditions under which a given logic output pin goes into the
deactive state. The syntax and behavior of this command is identical to that of the
LOA command.
Please refer to the description of the
LOA command for more information, including examples.
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.
8.88. LOEN -- Enable Automatic Logic Output Status
Messages
This command controls whether or not logic output status messages are sent automatically. If LOEN is
enabled, then a logic output query (LO*?) is performed any time any of the states change on the
logic output pins. For example, if all logic outputs are currently in the low state ('0') and LOEN is
enabled, then if logic output 12 changes state to '1', the following status message will be generated:
S01LO*00000000000100000000
A status message is only generated if there is a state change. This helps keep data traffic to a
minimum.
This command is a boolean command. See
Section 6.1 for more information on this type of command.
This command is saved to non-volatile memory only as part of a preset. The state of this command
will be restored after power-up only if a preset is saved and that preset is set to be the power-on
preset.
Example Description Status Message
S01LOEN1
Enable automatic logic output status messages.
S01LOEN1
S01LOEN0
Disable automatic logic output status
messages.
S01LOEN0
S01LOEN2
Toggle automatic logic output status messages.
S01LOENx , where x is 0 or 1
depending on the current setting of
LOEN.
