Limit Command Field is filled with the value that corresponds to the limit or operation that is
to be executed, along with the Vertical or Horizontal Absolute Position to be Set Field if needed,
and then issue the appropriate CIP command from the PLC. CIP Setup is similar to the Move
Command, except that the attribute field is set to 0xc0ff and the source element field points to
the above Limit Command Buffer. The following is a list of commands that can be executed.

3-5.1 TORQUE LIMIT COMMANDS
Torque Limit Commands are used to set operational safety limits and calibration commands
to the cannon. There are separate torque limits for the horizontal, vertical up and vertical down
movements, along with limits for vertical and horizontal detection of movement stoppage. The
structure of the PLC buffer for the Torque Limit Commands is as follows.
Figure 3-5.1.1 PLC Torque Limit Command Buffer
Torque Limit Command Field is filled with the value that corresponds to the operation that
is to be executed, along with either the 16 bit integer value or the 32 bits IEEE 754 floating
point value, and then issue the appropriate CIP command from the PLC. CIP Setup is similar
to the Move Command, except that the attribute field is set to 0xb3ff and the source element
field points to the above Torque Limit Command Buffer. The following is a list of Torque Limit
Commands that can be executed.
