status on input pin XTRI, if not used for 3-state control, usable as hardware flag for software use
status on input pin ITRI, if not used for 3-state control, usable as hardware flag for software use
status of the internal ‘FIFO almost filled’ flag
status of the internal ‘FIFO overflow’ flag
copy of bit DPROG, can be used to detect power-up and start-up fails
error flag of scalers output formatter, normally set, if the output processing needs to be
interrupted, due to input/output data rate conflicts, e.g. if output data rate is much too low and all
internal FIFO capacity used
status of the field sequence ID at the scalers input
status of the field sequence ID at the scalers output, scaler processing dependent

Output field ID is field ID from scaler input
Output field ID is task status flag, which changes every time a selected task
is activated (not synchronized to input field ID)
