STATus:ALARm:ENABle <enable_val>

STATus:ALARm:ENABle?

Description

This command enables bits in the enable register for the Alarm Register group. The selected bits are then reported to the Status Byte.

Used With:

• 34901A   20 Channel Multiplexer (2/4-wire) Module
• 34902A   16 Channel Multiplexer (2/4-wire) Module
• 34907A   Multifunction Module (digital input and totalizer channels only)
• 34908A   40 Channel Single-Ended Multiplexer Module

Parameters

Name	Type	Range of Values	Default Value
<enable_val>	Numeric	An integer from 0 to 65535, specifying the alarms to enable as a bit sum.	This is a required parameter.

Remarks

• The following table lists the bit definitions for the alarm enable register.

Bit #	Bit Name	Decimal Value	Definition
0	Alarm 1	1	An event has occurred on Alarm 1.
1	Alarm 2	2	An event has occurred on Alarm 2.
2	Alarm 3	4	An event has occurred on Alarm 3.
3	Alarm 4	8	An event has occurred on Alarm 4.
4	Queue Not Empty	16	The alarm queue is not empty.
5	Queue Overflow	32	An alarm queue overflow event has occurred.
6	Alarm 1	64	Alarm 1 is triggered.
7	Alarm 2	128	Alarm 2 is triggered.
8	Alarm 3	256	Alarm 3 is triggered.
9	Alarm 4	512	Alarm 4 is triggered.
10-11	Not Used	1024-2048	0 is returned.
12	Lower Limit	4096	A lower limit alarm has occurred.
13	Upper Limit	8192	An upper limit alarm has occurred.
14-15	Not Used	16384-32768	0 is returned.

Return Format

The query reads the enable register and returns a decimal value that corresponds to the binary-weighted sum of all bits set in the register. For example, if bit 1 (decimal value = 2) and bit 2 (decimal value = 4) are enabled, the query will return +6.

Examples

The following command enables alarm registers 0 through 3.

STAT:ALAR:ENAB 15

The following query returns a the binary sum equivalent to the enabled registers.

STAT:ALAR:ENAB?

Typical Response: +15
