It is coupled to the execution sequence identification number, and the sequence state of the execution sequence is set as starting；
In embodiments of the present invention, if detection meets entry condition, the equipment shape body for being related to equipment setting is positive busy, it will
It is to open that the sequence state that the equipment that sequence is related to is associated with to the execution sequence identification number, and the execution sequence is arranged, which will be executed,
It is dynamic；If detection is unsatisfactory for entry condition, cancels and this time operating.
S13, based on the sequence state started, the equipment state of associate device is set on one by one in a designated order
Begin to start, so that associate device carries out start-up operation based on the equipment state for starting starting；
In embodiments of the present invention, based on the sequence state started, the equipment state of associate device is set on
Begin to start, associate device is themselves based on the equipment state for starting to start and carries out beginning start-up operation.
S14, when the equipment state for detecting all associate devices is normal operation, then by the sequence of the execution sequence
State is changed to be currently running.
Step S14 step specific as follows:
Successively detect whether the equipment state of associate device is normal operation；
If the equipment state of associate device is normal operation, the sequence state for executing sequence is changed to transporting
Row.
Fig. 3 is the flow chart provided in an embodiment of the present invention for stopping the dynamic corresponding equipment sequence control method of operational order,
When operational order is halt instruction, step S2 specifically comprises the following steps:
S20, determine that the corresponding sequence state for executing sequence is non-stopping；
In embodiments of the present invention, it is non-stopping referring to except just in halted state in addition to other sequences state, comprising:
Stationary state is currently running state, just in emergency stop state and execution sequence fault in production state, works as reception just in starting state
When to no-operation instruction, if sequence state, which is in non-, thens follow the steps S212 just in halted state, if sequence state is
Halted state illustrates that the no-operation instruction is therefore repetitive operation cancels this no-operation instruction.
S21, judge to be in the positive busy condition of equipment with the presence or absence of equipment in associate device, if judging result be it is no, meet
The corresponding operating condition of halt instruction；
Step S3 specifically comprises the following steps:
S22, to set the equipment state of associate device to equipment just busy, sets the sequence state for executing sequence to
Stop；
In embodiments of the present invention, if there are equipment to be in the positive busy condition of equipment in associate device, cancel and this time stopping
Operation thens follow the steps S22 if being in the positive busy condition of equipment there is no equipment in associate device.
S23, based on the sequence state stopped, release associate device associated with other execution sequences and currently hold
The association of row sequence, and be set as starting by the equipment state for executing the associate device of sequence onrelevant with other in a designated order
Stop, releasing and current execute being associated with for sequence and the associate device that remains static；
In embodiments of the present invention, other execution sequences refer to other execution sequences except when except preceding execution sequence,
All associate devices each mean equipment associated with sequence is currently executed.
S24, when being associated with of sequence is executed with current when releasing all associate devices, then the sequence state for executing sequence is changed
It is static.
In inventive embodiments, emergency stop operation instruction includes: artificial emergency stop operation instruction and the emergency stop operation based on failure
Instruction, artificial emergency stop operation instruction are that manual control machine system starts emergency stop, when encountering production accident on production line, need people
