STATus:ALARm:ENABle
Syntax
STATus:ALARm:ENABle <enable_value>
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:
34921A through 34925A Multiplexer Modules
34950A Digital I/O Module (digital input and counter channels only)
34952A Multifunction Module (digital input and totalizer channels only)

5 |
Queue Overflow |
32 |
Alarm data lost due to alarm queue overflow. |

6-15 |
Reserved |
Reserved |
Reserved for internal use. |
Use the <enable_value> parameter to specify which bits will be reported to the Status Byte. The decimal value specified corresponds to the binary-weighted sum of the bits you wish to enable in the register. For example, to enable bit 0 (decimal value = 1), bit 1 (decimal value = 2), and bit 4 (decimal value = 16), the corresponding decimal value would be 19 (1 + 2 + 16).
The *CLS (clear status) command will not clear the enable register but it does clear all bits in the event register.
The STATus:PRESet command will clear all bits in the enable register.
Return Format
The query command reads the enable register and returns a decimal value which corresponds to the binary-weighted sum of all bits set in the register. For example, if bit 1 (decimal value = 2) and bit 4 (decimal value = 16) are enabled, the query command will return "+18".
Examples
The following command enables bit 1 (decimal value = 2) and bit 4 (decimal value = 16) in the enable register.
STAT:ALAR:ENAB 16
The following query returns which bits are enabled in the register.
STAT:ALAR:ENAB?
Typical Response: +16
