Y_PK22_PackML22_StateDiagram

The Y_PK22_PackML22_StateDiagram function block handles the operation of the state machine, including mode and state transitions, as defined in the OMAC PackML specification TR88.00.02 - 2022. This function block, when first enabled, initializes the machine to be in Mode 3 (Manual Mode) and in the Aborted state.

Parameters

*	Parameter	Data Type	Description	Default
VAR_IN_OUT
V	Cfg_ModeNames	#19497	An array of strings containing the names of the different Unit modes of operation
V	Cfg_ModeTransitions	#19492	An array of acceptable mode transition states. Mode changes into the NEW MODE can only be performed at the chosen states. Each element in the array represents a mode, and each bit in the array element represents a state. (Ex. To allow Mode Transitions for Mode 1 at Aborted (bit 9), Stopped (bit 2), and Idle (bit 4) states 0000 0000 0000 0000 0000 0010 0001 0100 = 16#0000_0214 = DINT#532 = Cfg_ModeTransitions[1] )
V	Cfg_StateNames	#19497	An array of strings containing the names of all the PackML states
V	Cfg_DisableStates	#19492	An array representing each mode and their states. Each mode can disable certain states.(Ex In Manual Mode (Mode 3) disable Holding(10), Held(11), UnHolding(12), Suspended(5), Suspending(13), UnSuspending(14),Completing(16), Complete(17) = 0000 0000 0000 0011 0111 1100 0010 0000 = 16#0003_7C20 = DINT#228384 = Cfg_DisableStates[3])
V	UnitMachine	#60397	Structure containing all the information about the machines current state of operation for all EMs and CMs

B	Cmd_Suspend	BOOL	Setting this bit sends the ‘Suspend’ command to all enabled and active EMs if it is a legal transition from the current machine state, otherwise the command will be ignored	FALSE
B	Cmd_UnSuspend	BOOL	Setting this bit sends the ‘UnSuspend’ command to all enabled and active EMs if it is a legal transition from the current machine state, otherwise the command will be ignored	FALSE
B	Cmd_Abort	BOOL	Setting this bit sends the ‘Abort’ command to all enabled and active EMs if it is a legal transition from the current machine state, otherwise the command will be ignored	FALSE
B	Cmd_Clear	BOOL	Setting this bit sends the ‘Clear’ command to all enabled and active EMs if it is a legal transition from the current machine state, otherwise the command will be ignored	FALSE
B	Cmd_Complete	BOOL	Setting this bit sends the ‘Complete’ command to all enabled and active EMs if it is a legal transition from the current machine state, otherwise the command will be ignored	FALSE
VAR_OUTPUT
B	EnableOut	BOOL	Indicates that the outputs of the function are valid
B	Clearing	BOOL	When this bit is set, the machine is in the ‘Clearing’ state
B	Stopped	BOOL	When this bit is set, the machine is in the ‘Stopped’ state
B	Starting	BOOL	When this bit is set, the machine is in the ‘Starting’ state
B	Idle	BOOL	When this bit is set, the machine is in the ‘Idle’ state
B	Suspended	BOOL	When this bit is set, the machine is in the ‘Suspended’ state
B	Execute	BOOL	When this bit is set, the machine is in the ‘Execute’ state
B	Stopping	BOOL	When this bit is set, the machine is in the ‘Stopping’ state
B	Aborting	BOOL	When this bit is set, the machine is in the ‘Aborting’ state
B	Aborted	BOOL	When this bit is set, the machine is in the ‘Aborted’ state
B	Holding	BOOL	When this bit is set, the machine is in the ‘Holding’ state
B	Held	BOOL	When this bit is set, the machine is in the ‘Held’ state
B	UnHolding	BOOL	When this bit is set, the machine is in the ‘UnHolding’ state
B	Suspending	BOOL	When this bit is set, the machine is in the ‘Suspending’ state
B	UnSuspending	BOOL	When this bit is set, the machine is in the ‘UnSuspending’ state

B	Completing	BOOL	When this bit is set, the machine is in the ‘Completing’ state
B	Completed	BOOL	When this bit is set, the machine is in the ‘Complete’ state
B	ModeChangeNotAllowed	BOOL	When this bit is set, the requested Mode change isn’t allowed and the machine will remain in the current mode and state.
V	Sts_StateCurrent	DINT	Number in decimal corresponding to the current state of the machine
V	Sts_StateCurrentName	STRING	The name of the current state of the machine
V	Sts_StateCurrentBits	DWORD	DWORD indicating the current state the machine is in (Ex. If Sts_StateCurrentBits[x] = 1, then the machine is in State x)

Notes

Should always be enabled when program is running to ensure proper operation of the state machine.
