MX_WRITE – Write a Matrix/Vector to the console/system log

Block SymbolLicensing group: STANDARD

Function Description
The function block MX_WRITE can write a vector or matrix to the console or the system log. The severity of the console/system log output is set by the parameter mode. The function block is very useful for debugging purposes of matrix/vector algorithms.

The output references yMV is always set to the input reference uMV. If RUN = off then nothing else is done otherwise matrix or vector is written to the system log if the configured target logging level for function blocks contains the configured mode. Format of each matrix/vector element is determined by parameters mchars and mdec.

The error flag E is set to on if:

the reference uMV is not defined (i.e. input uMV is not connected),
$3 > mchars > 25$ ,
$0 > mdec > mchars - 2$ .

This block does not propagate the signal quality. More information can be found in the 1.4 section.
