7 AK Host Operation
•
If the system is occupied by executing a previous function, the new start of a control
command will lead to the response 'BS' (busy) in the data block of the response. The
running function will not be disturbed. Exception: The command was a software reset.
•
If the system is operated in manual operation mode, also the command 'remote' will be
responded with 'BS'. In this mode only read commands can be used. All control and write
commands will be responded with 'BS'.
•
If the data or parameters transfer is not complete (i.e. not expected format) in the
command telegram of the system, the host computer will get a 'SE' (Syntax Error) in the
data block of the response.
•
If the system doesn't work with data or parameters of the command (data error,
parameter error) the host computer will get a 'DF' (Data Failure) in the data block of the
response.
•
All setpoints set with write 'E' commands will be saved when testo CU-2 will be shut
down and they will be restored after rebooting and set to standby or measurement mode.
