MOLBOX1+™/MOLBOX1+S, MOLBLOC TERMINAL OPERATION AND MAINTENANCE MANUAL
4.4.1.2
The molbox1+ contains an 8 bit Standard event register that reflects specific
molbox1+ events that are not RPT dependent. Enabled events in this register
will set or clear the ESB bit of the status byte register.
This register can be read using the "*ESR?" query. Each of these status bits can set
the ESB bit of the status byte register, causing a SRQ to occur IF the ESB bit is
enabled to do so. The Standard Event Status Enable Register ("∗ESE" program message)
determines which of these flags are able to assert the ESB bit. The description
of these bits are given as:

PON: Power On (Bit 7)
Indicates that the molbox1+ power has been cycled since the last time this
bit was read or cleared.
URQ: User Request (Bit 6)
Indicates that the molbox1+ was set to local operation manually from the
front panel by the user (pressing the ESC key).
CMD: Command Error (Bit 5)
Indicates that a remote command error has occurred. A command error is
typically a syntax error in the use of a correct program message.
EXE: Execution Error (Bit 4)
Indicates if a remote program message cannot be processed due to device
related condition.
DDE: Device Dependent Error (Bit 3)
Indicates that an internal error has occurred in the molbox1+ (e.g., a transducer
time-out).
QYE: Query Error (Bit 2)
Indicates that an error has occurred in the protocol for program message
communications. This is typically caused by a program message being sent
to the molbox1+ without reading a waiting reply.
RQC: Request Control (Bit 1)
This bit is not supported as the molbox1+ cannot become the active
controller in charge.
OPC: Operation Complete (Bit 0)
Indicates that the molbox1+ has completed all requested functions.
