Outline of operation
● This instruction requests to start the logging trace function for the number specified by [n].
● There is no problem even if the logging trace start request is made while the logging trace is
being started or the logging trace start is being processed.
● The logging trace is set using the configuration menu of the tool software FPWIN GR7.
● For setting the logging trace to be automatically started, or starting it with the tool software
FPWIN GR7, there is no need to execute the LOGST instruction.
