Model 9200 Programmable Dual-loop Controller
Chapter 4 - SERIES 9200 “Opcode”s
Programmer Description
The SERIES 9200 series Atmosphere/Temperature Recipe Programmer provides a convenient operator interface and recipe programmer.
The programmer uses enhanced “Opcodes” that reduce the number of steps required for a program. Each step consists of an “opcode”, a temperature value, an atmosphere value, and an option value. The “opcode” determines how and if each of the three values are used.
“Opcode”s
ALARM This alarm function is used to notify the operator that an operation is complete or that a manual action is required. By use of the Passcode and Alarm Screen, up to 99 User Alarms can be assigned, with a short Text on each. Displayed during an active Alarm Condition. The program waits until the alarm is acknowledged to proceed.
ATM_INQ The atmosphere inquiry is used to wait for the actual atmosphere to reach the value specified in the “atm” (atmosphere) field.
The options are:
•wait, reach within band;
•wait up, reach or exceed the setpoint;
•wait down, reach or be less than the setpoint.
The default band can be set under the Configuration menu and is typically 10 (i.e. 0.10 percent carbon).
•The SET_WAIT “opcode” will change the band limit
•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.
BRANCH The Branch “opcode” can change program flow based upon an inquiry “opcode”. The temperature data is interpreted as a program step if the inquiry is true and the atmosphere data as a program step if the inquiry is false.DELAY This “opcode” is used when a short delay is needed. The option value is the delay time in seconds.
