NOTES:
*
The SPI I/O list defines the Processing bit as being cleared if the unit is not processing; otherwise it is SET.
Elsewhere on the chart:
●
If a bit is not shown to be SET, it is cleared.
●
The System Alarm bit is SET if an alarm is present. It is the logical OR of Process alarm and Machine alarm.
●
Processing, System Alarm, Process Alarm and Machine Alarm bits are repeated for Process Status, Machine 1
Status and Machine 2 Status.
