The USS_Drive_Control instruction exchanges data
with a drive by creating request messages and inter-
preting the drive response messages. A separate func-
tion block should be used for each drive, but all USS
functions associated with one USS network and PtP
communication port must use the same instance data
block. You must create the DB name when you place
the first USS_Drive_Control instruction and then refer-
ence the DB that was created by the initial instruction
usage.
STEP 7 automatically creates the DB when you insert
the instruction.
