Description
pressure_set_force
Scaling is 16-bit, fixed-
point binary with 1-bit sign
at MSB and 7-bit decimal
at LSB.
0x2096 When pressure_set_force = 0, the gas mode is set to Automatic mode at
the power supply.
When pressure_set_force > 0, the CNC controls the gas pressure and the
pressure controls on the power supply are disabled.
pressure_set_force value :01062096xxxxcc
Where xxxx equals the hex value of the PSI decimal value multiplied by 128
cc equals LRC (checksum)
Samples:
45 PSI :010620961680AD0D0A
45 PSI × 128 = 5760 = 0x1680
Response: :010620961680AD
70 PSI :010620962300200D0A
70 PSI × 128 = 8960 = 0x2300
Response: :01062096230020
fault_code 0x2098 Reads the fault condition.
Sample: :010420980001420D0A
Response: :010402006F8A
fault_code value :010402xxxxcc
where xxxx equals the hex value of the decimal fault code
cc equals LRC (checksum)
0x006F = 111
