*SRE?
*STB?
Service Request (SRQ) generation
The GPIB controller automatically handles the actions that
are triggered by the bit rsv in the status register STB.
After generating a service request and subsequent query
with *STB? from the host, the register is cleared.
The scheme is illustrated in the diagramm below.
A SRQ is generated as soon as the bit rsv in the Status Byte
register (STB) is set and the corresponding bits for events
that can cause a SRQ are activated in the Service Request
Enable Register (SRE).
Which events can cause a service request is selected with
the Service Request Enable Register by the command *SRE
<CHAR>.
The status register STB consists of these bits:
Bit 0:
Bit 1:
U = User defined
D = Set after power on
z = State of the indicated information
OPC = OPeration Complete bit
EXE= EXecution Error
QYE= QuerY Error
CME= CoMmand Errors
DDE= Device Depend Error

Legend:
CC/CV/CP/CR = currently active regulation mode
Reduce Power = power derating active (PSI 9000 series only)
Fct. at start/running/stepping = function manager status
Input
Output enable = auto-on for the output is activated
MODE_A/B/AB/BAT = actual operation mode, chosen by the rotary switch
MODE_CR1/CR = currently selected resistance range (CR1 is the smaller one)
LOCAL = device is in local mode, remote control is not allowed
REMOTE = device is remotely controlled by a digital interface card
EXTERNAL = device is controlled by the analogue interface card resp. the
built-in analog interface
Function mode = function manager active

The event bits of the various registers report to the STB, if
events have occured that are enabled to be reported, by the
corresponding bits in the enable registers (*ESE, *SRE resp.
STAT:QUES:ENAB, STAT:OPER:ENAB).

Output
err, Error queue full; this queue is cleared by reading
it and the bit is also reset. The list can hold up to 4

ques, Questionable status register is active (on or
more events have occured)
Not used
esr, the standard Event Status Register (ESR), mas-
ked by the Event Status Enable Register (ESE), is
signalising that one or more events have occured
rsv, always active
oper, signalises, that one or more events have
occured and are stored in the Operation Status
