mally, a 0 value of STATUS means that the command
completed OK and a non-zero status indicates some

Command
Operation
Step 1. To start a command, place the command
number into the first word of the output
table.
Step 2. The Input Table contains the response for
that command.
Step 3. If a selected command needs other data
with it, the other words in the output table
should be filled in first, then the command
number. Example:
• WRITEPARAM0, should have
PARAMETER0 Data placed into the
output table before the command
number is written, otherwise the com
-
mand will fail.
