4.3.6 State machine
Every machine module features one state machine.  State machine ( 77)
• If a machine module is integrated in the machine module tree (if it is not decoupled from the
MMT), the state machine of the master module controls all state machines of the lower-level
machine modules.
• When all slave modules have changed to the requested state, the master module also changes
to the requested state.
Exception: During the initialisation, all machine modules are in the "INIT" state and,
independently of the slave or master, change to the "READY" state if it is enabled:
State transitions - overview
The following status diagram illustrates the possible operating states of the state machine:
• After the start (switch-on / re-initialisation), the module is in the "Init" state.
• In standby/waiting mode, the module is in the "Ready" state.
• "Warning" is a special status (independent, "orthogonal" state), which does not influence the
operational performance of the machine module.
