MCA527

Command name CMD_QUERY_STATE

Compatibility Compatible to the MCA166 command.

Execution right Not necessary

Description The command reads the state.

Format integer integer integer long integer

Parameter preamble command 0 0 end flag

Byte string (HEX) A5 5A 5A 00 00 00 00 00 00 00 B9 9B

Result data array

Byte offset 0 MCA acquire mode unsigned short MODE_MCA = 0

MODE_MCS = 1

Byte offset 2 Preset (automatic stop condition)

unsigned short PRESET_NONE = 0

PRESET_REAL = 1

PRESET_LIVE = 2

PRESET_INT = 3

PRESET_AREA = 4

Byte offset 4 Preset value unsigned long

Byte offset 8 MCA mode: elapsed preset

MCS mode: elapsed MCS channels

unsigned long

Byte offset 12 Repeat value unsigned short

Byte offset 14 Elapsed sweeps unsigned short

Byte offset 16

MCS time per channel [ * 10 msec]

unsigned short

Byte offset 18 Elapsed time per channel [ * 10 msec] unsigned short

Byte offset 20 Real time [sec] unsigned long

The fractional digits of the real time are

returned by CMD_QUERY_STATE527_EX,

byte offset 80.

Byte offset 24 MCA mode: counts per second

MCS mode: counts per channel

unsigned long

Byte offset 28 Dead time [msec] unsigned long

Byte offset 32 Busy time [msec] unsigned long always 0 at MCA527

Byte offset 36 MCA channels unsigned short

Byte offset 38 Threshold [%] unsigned short

See CMD_QUERY_STATE527 and

CMD_SET_THRESHOLD

Byte offset 40 LLD unsigned short

Byte offset 42 ULD unsigned short

Byte offset 44 ROI begin (preset integral/area) unsigned short

Byte offset 46 ROI end (preset integral/area) unsigned short

31 For general mode 3 and 4 (see CMD_SET_GENERAL_MODE), only PRESET_REAL is supported, PRESET_LIVE,

PRESET_INT and PRESET_AREA are unsupported and mean the same like PRESET_NONE.

32 Since firmware version 13.00.

33 Older applications for the MCS mode used the counts per channel to calculate the counts per second. However, this is inexact.

For this reason, since firmware version 13.00, the 'counts per second' for both modes are (additionally) returned at byte offset

116. Newer applications for the MCS mode should use this parameter.
