Requests the hard arc count limit; the returning
packet contains 4 data bytes (a 32-bit value)
indicating the limit.
This value is set with command 9.

request
active recipe
step, ramp/
run status,
and ramp/run
time
remaining
Requests the active recipe step number, the
ramp/run status, and the ramp/run time
remaining; the returning packet contains 4 or 6
data bytes depending on the recipe type.
• First byte = Active recipe step number
• Second byte = Ramp/run or recipe type
status (1 = ramp, 2 = run, 4 = continuous
recipe, 5 = discrete recipe)
• Third and fourth bytes = Ramp/run time
remaining (in tens of milliseconds, or 0 if
a ramp or recipe has run to completion) if
timed recipe is running
OR
• Third, fourth, fifth, and sixth bytes =
Joules remaining if discrete or continuous
joule recipe is running
Note: If output is shut off either through a fault
or an off command, the active recipe step
number, ramp/run status, and ramp/run
time remaining will all maintain their
last value. A subsequent off command
will set recipe step number to 1 (or 0 if
recipes are not active) and set ramp/run
time remaining to 65535 if the time is
nonzero. If the run segment of the last
recipe step is 0, ramp/run time
remaining is set to 65534 and never
counts down.
