command parameter; valid values for this parameter are:
•PRE
Sends a PackML Prepare command, which represents the PackML state transition from
STOPPED to STARTING. In CLARiTY terms it is equivalent to pressing the button while
the system is in the Shut Down state. The success response is sent when the system state reaches
the target state. The failure response is sent if the state transition is rejected. If the system is
already in the target state when the command is received, a success response is immediately sent
without performing any action. If the system is in a state other than the source or target states for
this transition, the command is immediately rejected.
•STA

READY/HELD to STANDBY. In CLARiTY terms it is equivalent to pressing the button
while the system is in the Offline state. The success response is sent when the system state
reaches the target state. The failure response is sent if the state transition is rejected. If the system
is already in the target state when the command is received, a success response is immediately
sent without performing any action. If the system is in a state other than the source or target
states for this transition, the command is immediately rejected. This command may fail if there is
no job selected.
•STP

STARTING/HELD/READY/STANDBY/PRODUCING to STOPPING or ABORTED to
STOPPED. In CLARiTY terms it is equivalent to clearing any faults and then pressing the
button while the system is in the Offline, Starting up, or Running states, or equivalent to clearing
any faults while the system is in the Shut Down state and a fault has occurred. The success
response is sent when the system state reaches the target state. The failure response is sent if the
state transition is rejected. If the system is already in the target state when the command is
received, a success response is immediately sent without performing any action. If the system is
in a state other than the source or target states for this transition, the command is immediately
