M4557 - Model 9210 Nitriding Controller
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.
