S01LOEN?
Query automatic logic output status messages.
S01LOENx , where x is 0 or 1
depending on the current setting of
LOEN.
8.89. LOK -- Delete One or All Logic Output Pin Commands
This command "kills" or deletes all commands for a given logic output pin. In other words, the
commands associated with
LOA and LOD will be deleted for the specified logic output. A wildcard
character can also be specified for the logic output pin, in which case the commands for all logic
output pins will be deleted.
Using this command is more efficient than deleting one command or pin at a time since this command
deletes them all at once and requires fewer writes to non-volatile memory.
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
S01LOK5
Delete all the commands associated with logic output pin 5. This one
command is equivalent to executing the commands ' S01LOA5, ' and '
S01LOD5, ' except that this command is more efficient.
S01LOK5
S01LOK*
Delete all the commands associated with all logic output pins. This one
command is equivalent to executing the commands ' S01LOA1, ' and '
S01LOD1, ' for each logic output, except that this command is much
more efficient.
S01LOK*
8.90. LOM -- Mask Logic Output Pins
This command is used to mask (i.e., disable) logic output pins. The mask consists of 20 fields (one for
each logic output) that can each be set to 0 or 1. If the mask bit for a given logic output is set to 1,
then the logic output pin works normally. If the mask bit for a given logic output is set to 0, then the
logic output is disabled. When a a logic output is disabled, it is "frozen" in whatever state it is in when
it is disabled. The output pin's state will not change when the condition that drives it (via
LOA and
LOD) changes. However, any changes to that pin caused by setting the values with an LO command
will affect the output pin value. For instance, you could disable (mask) a pin and then explicitly set its
value to low with the
LO command.
When a logic output pin is re-enabled, it will be updated to the current status of whatever condition
drives it (via (
LOA and LOD).
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.
