5.8.2 Device Status Flags #2
The bits in this word indicate the current mismatch status for each data variable
which is verified. When the bit is set (1) the variable is in a mismatched condition.
The mismatch may be cleared by performing a download to the instrument or by
performing an upload (copying the read data base to the write data base). If the
PLC database is downloaded to the instrument, the mismatch condition will not
clear until the complete database has been read back from the instrument.
