This bit is set when a trigger event occurs on a 1260-114
digital IO card.
Waiting For Arm
Bit 6, Bit weight = 64 decimal = 40
hexadecimal
This bit is set when a Scan List has been defined, but the
1256 is not armed. Use the INIT:IMMEDIATE or
INIT:CONTINUOUS command to arm the 1256
Waiting for Trigger
Bit 5, Bit weight = 32 decimal = 20
hexadecimal
This bit is set when a Scan List has been defined,
and the 1256 has been armed, but is waiting for a
trigger. The TRIGGER:SOURCE command may be
used to select a trigger source. If the trigger source
is “BUS”, then the *TRG command will satisfy a
trigger
Settling
Bit 1, Bit weight = 2 decimal = 2
hexadecimal
This bit is set when the relays are settling due to a
CLOSE, OPEN, or SCAN operation. This bit is
cleared after the settling time has elapsed.
All of the other bits of this register are not used by the 1256. These
bits will return a value of 0 when read.
The
Operation Status Enable Register
enables individual bits to
pass through to the Operation Status Event Register. The bits of
the
Operation Status Enable Register
are ANDed with the bits of
the
Operation Status Condition Register
. If both bits are set, then
the corresponding bit in the
Operation Status Event Register
is set.
For example, if bits 1, 5, and 6 of
the Operation Status Condition
Register
are set, and bits 5 and 6 of
the Operation Status Enable
Register
are set, then bits 5 and 6 of the
Operation Status Event
Register
will be set.
The
Operation Status Event Register
latches the status
information. Once a bit is set in the
Operation Status Event
Register
, it remains set until the bit is cleared by reading the
register with the STATUS:OPERATION:EVENT? query, or by
sending the *CLS command.
When any of the bits of the
Operation Status Event Register
are
set, bit 7 of the
Status Byte Register
will be set.
The
Questionable Status Register
is not used by the 1256. When
the
Questionable Status Condition Register
or
Questionable Status
Event Register
are read, they will return a value of 0. The
