SPINDLECONTROL ARRAY[1..50]
OF BYTE This output control which spindles to run when the station is started.
Takes one of the following values:

0: Connect normally. The bolts connected to the spindle will run
the tightening program specified in the mode table when
station is started.

1: Disconnected with OK status

2: Disconnected with NOK status

3: Do not run during next cycle
The difference between "Disconnected" and "Do not Run" is that in
the first case the bolt connected to the spindle will be reported with
the given status and in the latter nothing is reported for the bolt. In
neither case will the bolt start when the station is started.

OF REAL Reports current motor temperature in centigrade for all spindles.
Updated at cycle start and end.
CYC_TO_SERVICE ARRAY [1..50]
OF DINT Reports number of cycles before service should take place.

True False
True
Cycle data is dropped for this device
