Message Available Bit 4 (16)
Indicates that at least one reply message is waiting in the RPM4 IEEE-488 output
queue.
Indicates that at least one reply message is waiting in the RPM4 IEEE-488 output
queue.
ERROR
Error Queue Not Empty Bit 2 (4)
Indicates that at least one command error message is waiting in the RPM4 IEEE-488
error message queue. Use the “ERR?” query to get this message.

RSR
Ready Summary Bit 0 (1)
Indicates that an enabled bit in the Ready Status Register became set.
Indicates that an enabled bit in the Ready Status Register became set.
4.5.3
STANDARD EVENT REGISTER
The RPM4 contains an 8 bit Standard event register that reflects specific RPM4 events.
Enabled events in this register will set or clear the ESB bit of the Status Byte Register.
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:

User Request Bit 6 (64)
Indicates that the RPM4 was set to local operation manually from the front panel

CMD
Command Error Bit 5 (32)
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 (16)
Indicates if a remote program message cannot be processed due to device
related condition.

DDE
Device Dependent Error Bit 3 (8)
Indicates that an internal error has occurred in the RPM4 such as a transducer time-
out.

QYE
Query Error Bit 2 (4)
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 RPM4 without reading a waiting reply.
communications. This is typically caused by a program message being sent to
the RPM4 without reading a waiting reply.
RQC
Request Control Bit 1 (2)
This bit is not supported as the RPM4 cannot become the active controller in charge.
OPC
Operation Complete Bit 0 (1)
Indicates that the RPM4 has completed all requested functions.
