M4557 - Model 9210 Nitriding Controller
SSi Manual SERIES 9210-M4557-Nitriding Page 44 of 44
values are within the deviation limit band. If the temperature falls outside of the band, the ramp
will wait until the temperature is within the band.
GZRAMP
This is a
Guaranteed Ramp
opcode for a zone. The process value must be within the deviation
band to allow the ramp timer to run. The temperature data is the temperature set point, the
atmosphere data is the atmosphere setpoint, and the option data is the ramp time in hours and
minutes. The band limit can be changed by the
SET_WAIT
opcode.
GZ_SOAK
This is a
Guaranteed Soak
opcode for a zone. The temperature process value must be within the
deviation band to allow the soak timer to run. The option value is the soak time in hours and
minutes. The band limit can be changed by the
SET_WAIT
opcode.
HIGH_AL
This opcode is used to enable a high limit alarm on the temperature process and/or the
atmosphere process. The temperature data is the high limit point for the temperature process.
The atmosphere data is the high limit point for the atmosphere process. This alarm remains active
until the program ends.
HIGH_PO
This opcode is used to enable a high limit alarm on the temperature percent output and/or the
atmosphere percent output. The temperature data is the high limit point for the temperature
percent output. The atmosphere data is the high limit point for the atmosphere percent output.
This alarm remains active until the program ends.
ID_SET
This opcode is used to set the ID number to the value specified in the temperature data. The
atmosphere and option data are not used. The ID number is provided as a feature to track loads
or jobs and is not used by any controller.
ID_INC
This opcode increments the ID number by one. No data is required.
ID_INQ
This opcode is used to compare the ID value to the value in the temperature data. The option
data is equal, high, or low. 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.
IN_inq
The
Input Inquiry
opcode will allow the user to check one of the inputs for a specific value. The
temperature data is the value to check for. The atmosphere data is the input to check. The
options are wait, wait up, or wait down.
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.
JUMP
The
JUMP
opcode is used to go to another program when no return is needed. The option data is
the program number to execute next. This differs from the
GOSUB
opcode in that the
JUMP
will
not return to the calling recipe when the next recipe has finished.
LIMIT
This option is used to place a time limit on a wait or inquiry step. The option data is the time limit
to wait in hours and minutes. Should the time run out before the wait or inquiry is satisfied an
alarm occurs.
LOW_AL
This opcode is used to enable a low limit alarm on the temperature process and/or the
atmosphere process. The temperature data is the low limit point for the temperature process. The
atmosphere data is the low limit point for the atmosphere process. This alarm remains active until
the program ends.
