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.

This allows the control loop to recover from the change before continuing the program.


SET_FCM

This opcode sets the gas flow control mode. There are four options: Individual trim, Flow

control adjusts two valves, Ratio control – Maintains constant ratio between NH3 +, Auto switch –
Switches between Options 1 & 2 based on the DA switch point.

Individual Trim will adjust the Gas flow of a valve if Trim is enabled.

Flow Control adjusts the flows of all enabled valves by the same percentage.

Ratio Control maintains a constant total flow of gas into the furnace by adjusting only the
Ammonia and Dissociated Ammonia flows. This does not apply to the Nitrogen or Aux Valves.

SET_LP3

This opcode will set the Loop 3 setpoint, if applicable. The temperature data is the setpoint.

Set Loop 3 functionality is similar to the SET_BP opcode, except that there is no decimal place
applied on Set Loop 3.

SET_SL_VAL

This opcode will set the setpoint on an auxiliary slave controller. The temperature data is

the setpoint. The atmosphere data is the register to set. The option data is the instrument
number.

SET_VALVE

This opcode will set one of four valves. The temperature data is the setpoint. The

atmosphere data is the trim range. Setting the trim range to any positive number will enable the
trim for the selected valve. Setting the trim range to a 0 will disable the trim for the selected
valve.

Note: leaving the trim disabled will make no changes to the current trim configuration

.

The option data is the valve selction. The valve can be: Nitrogen, Ammonia, Disassociated
Ammonia, or Endo.


SET_WAIT

This opcode sets the band limits for the wait option or

Inquiry

opcodes. The temperature data

specifies the temperature band (i.e. +/- the value) and the atmosphere data specifies the
atmosphere band.

SETPT

This opcode is used to set the temperature and/or atmosphere set points. Either or both of the

set points can be specified. 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.

If both set points are specified the Wait applies to both.


SL_PV_INQ

The slave process variable inquiry is used to determine whether or not the auxiliary

instrument has reached the target input for its specific process variable.

SOAK

This opcode is an unconditional soak for the time (in hours and minutes) specified in the option

data.
