Here are the meaning of some of the values:
MachMd: machine mode, the state of the machine: 1: not yet started, 2: program running, 3: paused, 5: delayed start, 7: finished
DelVal: the delayed start time, in minutes
RemTime: the remaing time, in second (on my machine it’s always a multiple of 60)
FillR: fill ratio (I guess is a value between 0 and 100, stay at 0 for some program)
CheckUpState: the state of the check up test (I think you can run that from the application, didn’t check). 0 means the test wasn’t run, 1 the test is running and 2 the test ended or the test failed (I don’t know).
The various Pr values indicate which program is selected/running. You can get a json describing the program (and mapping the program number to names) with the cloud api.
