Batch Command-State Sequence

Sepasoft MES Module Suite

Transition Handling

This section demonstrates the command-state handling of a phase configured with Exposed set to True and State_Transition_Handling parameter set to Auto Mode

When State_Transition_Handling is set to PLI , make sure the input parameters follow the sequence outlined in this section.

To sync state to command in PLI mode, see:

system.mes.batch.queue.syncPLIStepState(batchQueueEntry, path)
enableSyncStepState property on the Batch Monitor and Batch Controller components

State_Transition_Handling parameter

State_Transition_Handling parameter values: PLI and Auto.

If State_Transition_Handling is set to PLI, the Batch Engine drives the Command, and the equipment PLC drives the State .
If State_Transition_Handling is set to Auto, the Batch Engine drives the Command and the Command drives the State.

Command = Command Number

None	=	0
Start	=	1
Pause	=	2
Resume	=	3
Hold	=	4
Restart	=	5
Stop	=	6
Reset	=	7
Abort	=	8

State Number = State

1	=	Idle
2	=	Running
3	=	Complete
4	=	Restarting
5	=	Resetting
6	=	Pausing
7	=	Paused
8	=	Holding
9	=	Held
10	=	Stopping
11	=	Stopped
12	=	Aborting
13	=	Aborted
17	=	Permissive Start

The batch engine writes Start and Command_Number 1. The PLC sets State_Number to 2 (Running). The batch engine writes that same value to State_Number_Ack. The batch engine then sets Command to None and Command_Number to 0. When the PLC sets State_Number to 3 (Complete), the batch engine writes 3 to State_Number_Ack. The batch engine writes Reset and Command_Number 7. When the PLC sets State_Number to 1 (Idle), the batch engine writes 1 to State_Number_Ack.
