The
LIMIT
opcode immediately following this opcode sets a time limit on the wait.
A
BRANCH
opcode immediately following this opcode can be used to change the program flow
based on the inquiry results.
QTCSET
This is the
Quench Instrument Setpoint
opcode. This will allow the user to set the setpoint for a
quench cycle. The temperature data is the temperature setpoint.
QUENCH
The
QUENCH
opcode is used to start a quench cycle. The quench cycle is independent of any
program that is running. The temperature data is the quench temperature controller set point.
The atmosphere data is the quench time in minutes. The option data can be used to control the
agitator speed, high or low, by Event # 6. Event # 6 OFF equals low speed, and Event # 6 ON
equals high speed. The quench temperature controller must be
Aux Instrument # 4
. The quench
cycle starts when the opcode is executed. The set point is sent to the quench temperature
controller, the timer is started, and the high-speed event is turned on if it is selected. When the
quench timer times out, the end of quench cycle (Event # 7) is turned on for one minute and the
high speed event is turned off.
RAMP
This opcode changes the temperature set point and/or the atmosphere set point linearly over
time. The option data is the total ramp time in minutes. The temperature data specifies the final
set point for the temperature set point. The atmosphere data specifies the final value for the
atmosphere se point.
RAMPR
This opcode changes the temperature set point at a rate of degrees per minute. The option data
is the final temperature set point and rate of degrees per minute.
RUN_SLAVE
This opcode will change the temperature set point of an auxiliary instrument at a rate of
degrees per minute. The temperature data provides the final setpoint. The atmosphere data is
the auxiliary instrument to change the setpoint on (1 – 12). The option data is the rate change in
degrees per minute.
RESET
This opcode is used to clear all stacks and timers and start a program. The temperature data is
interpreted as a program number and the atmosphere data as a program step. The option data
is not used. The RESET is useful in a weekend shut down program to restart the normal
operating program.
SET_AUX
The
Set Auxiliary Instrument Setpoint
opcode is used with other instruments in the process
such as flow control or belt speed. The temperature data is the set point and the option data is
the instrument number.
SET_BP
This opcode is used to set the backpressure set point. The atmosphere data is the atmosphere
setpoint. The options are:
wait: the PV must be within the wait limit band specified to continue the recipe
wait up: the PV must be at or above the set point to continue the recipe
wait down: the PV must be at or below the set point to continue the recipe.
An explanation of wait, wait up, and wait down options can be found at the end of this chapter.
SET_FACT
This opcode is used to set the CO factor or the H2 factor of the atmosphere controller. If the
atmosphere type for the loop is set to dew point then the H2 factor is set; otherwise the CO factor
is set. The temperature data is not used. The atmosphere data is used as the factor with decimal
places ignored. The options are:
