HH Sets the SP ramp-up-rate
Syntax HH p1,p2,p3
p1: Loop number (1 to 6) (1 or 2 on the CX1000)
p2: Enable/disable SP ramp-up-rate setting
(Off, On).
p3: SP ramp-up-rate value (1 digit to EUS
(100%))
Query HH[ p1]?
Example Set the SP ramp-up-rate of loop 1 (whose input
type is set to RTD type PT) to the maximum
value in the selectable range.

HL Sets the SP ramp-down-rate
Syntax HL p1,p2,p3
p1: Loop number (1 to 6) (1 or 2 on the CX1000)
p2: Enable/disable SP ramp-down-rate setting
(Off, On).
p3: SP ramp-down-rate value (1 digit to EUS
(100%))
Query HL[ p1]?
Example Set the SP ramp-down-rate of loop 2 (whose
scale range is set to 100.00 to 200.00) to the
minimum value in the selectable range.
HL2,ON,1
HM Sets the loop tag and tag
comment
Syntax HM p1,p2
