The USS_DRV instruction exchanges data with a drive
by creating request messages and interpreting the drive
response messages. A separate function block should
be used for each drive, but all USS functions associat-
ed with one USS network and PtP communication port
must use the same instance data block. You must cre-
ate the DB name when you place the first USS_DRV
instruction and then reference the DB that was created
by the initial instruction usage.
STEP 7 automatically creates the DB when you insert
the instruction.
