9.3.3 The state transitions in detail
The "Init" status is reached immediately after mains switching/device reset.
• The module application executes the initialisation. After the initialisation phase, the state
machine is to be set to the "Ready" status by setting the xEnableInitToReady input.
• The following input conditions must be met so that the respective state transition is reached:
Number State transition Condition
1 "Init""Ready" • SetState request by the master
baseChannelSetNominalState(MM_Address:= 0,
eState:=L_EATP_SMStates.Ready)
; and
• State transition is enabled by the module application
(xEnableInitToReady input = TRUE)
Note: When this method is passed through by every machine module (MM) during
the initialisation phase, all MMs are in the "Ready" status.
2 "Ready"
 "Manual"
• SetState request by the master
baseChannelSetNominalState(MM_Address:= 0,
eState:=L_EATP_SMStates
.Manual); and
• State transition is to be enabled by the module application in every subordinated
machine module (xDisableReadyToManual input = FALSE)
3 "Ready"
 "Service"
• SetState request by the master
baseChannelSetNominalState(MM_Address:= 0,
eState:=L_EATP_SMStates.Service);
and
• State transition is enabled by the module application
(xDisableReadyToService input = FALSE)
4 "Ready"
 "Automatic"
• SetState request by the master
baseChannelSetNominalState(MM_Address:= 0,
eState:=L_EATP_SMStates.Automatic);
and
• State transition is enabled by the module application
(xDisableReadyToAutomatic input = FALSE)
5...7 "Ready"
 "Mode(1...2)"
• SetState request by the master
baseChannelSetNominalState(MM_Address:= 0,
eState:=L_EATP_SMStates.Mode
(1...2));and
• State transition is enabled by the module application:
(xDisableReadyToMode(1...2) input = FALSE)
8 "Manual"
 "Ready"
• SetState request by the master
baseChannelSetNominalState(MM_Address:= 0,
eState:=L_EATP_SMStates.Ready); and
• Enable of the state transition by the module application
(xDisableManualToReady input = FALSE)
9 "Service"
 "Ready"
• SetState request by the master
baseChannelSetNominalState(MM_Address:= 0,
eState:=L_EATP_SMStates.Ready);
and
• State transition is enabled by the module application
(xDisableServiceToReady input = FALSE)
10 "Automatic"
 "Ready"
• SetState request by the master
baseChannelSetNominalState(MM_Address:= 0,
eState:=L_EATP_SMStates.Ready);
and
• State transition is enabled by the module application
(xDisableAutomaticToReady input = FALSE)
11 ... 13 "Mode 1...2"
 "Ready"
• SetState request by the master
baseChannelSetNominalState(MM_Address:= 0,
eState:=L_EATP_SMStates.Ready);
and
• State transition is enabled by the module application:
(xDisableMode(1...2)ToReady input = FALSE)
