)stores 

894, 16-bit words of arbitrary user data to non-volatile flash memory. A custom 
format can be designed for information storage. For example, the data could define 
a 32 by 28 word array to store information about each channel.

A Remote Signal Conditioning Unit’s Flash Memory has a finite lifetime of 
approximately 10,000 write cycles (unlimited read cycles). While executing 
DIAG:REM:USER:DATA once every day would not exceed the lifetime of the Flash 
Memory for approximately 27 years, an application that stored constants many times 
each day would unnecessarily shorten the Flash Memory's lifetime.

•

The <channel> parameter must specify a single channel only. The channel must 

be on an RSCU that supports the DIAG:REM:USER:DATA commands.

•

DIAG:REM:USER:DATA sends to the RSCU a definite length block of 894 

int16 values (1,792 bytes). The block must always be 894 words in length.

Use VXIplug&play function: hpe1422_sendBlockInt16(...)

extracts 894, 16-bit words of 

arbitrary user data from non-volatile flash memory (stored with the DIAG:REM 
:USER:DATA command).
