6.4.3 Application of the Status Reporting System
The purpose of the status reporting system is to monitor the status of one or several
devices in a system. To do this and react appropriately, the controller must receive and
evaluate the information of all devices. The following standard methods are used:

Operating Manual 1505.3896.12 - 14
Meaning
Operation Complete
This bit is set on receipt of the command *OPC after all previous commands have been executed.
Request Control
This bit is set if the instrument requests the controller function. This is the case when a hardcopy
is sent to a printer or a plotter.
Query Error
This bit is set if either the controller wants to read data from the instrument without having sent a
query, or if it does not fetch requested data and sends new instructions to the instrument instead.
The cause is often a query which is faulty and hence cannot be executed.
Device-Dependent Error
This bit is set if a device-dependent error occurs. An error message with a number between -300
and -399 or a positive error number, which describes the error in greater detail, is entered into the
error queue (see).
Execution Error
This bit is set if a received command is syntactically correct, but cannot be performed for other
reasons. An error message with a number between -200 and -300, which describes the error in
greater detail, is entered into the error queue (see).
Command Error
This bit is set if a command which is undefined or syntactically incorrect is received. An error
message with a number between -100 and -200, which describes the error in greater detail, is
entered into the error queue (see).
User Request
This bit is set on pressing the LOCAL key, i. e. when the instrument is switched over to manual
control.
Power On(supply voltage on)
This bit is set when the instrument is switched on.
