Data corresponding to area.
On the basis of above-mentioned technical proposal, the instruction execution module decision instruction information is the status command that resumes operation
When, stop control operation logic, running status file is recovered to the corresponding data of controller by data type and form
In region.
On the basis of above-mentioned technical proposal, the system also includes instruction sending module, for sending command information, refers to
Information is made to include preserving running status instruction and the status command that resumes operation；And it is capped timestamp for command information.
A kind of method for the access of nuclear power station DCS controller states, comprise the following steps：
Send command information and be capped timestamp for instruction, decision instruction information is effective, decision instruction information type：Work as finger
When to make information be running status store instruction, obtain the current all running state datas for obtaining control configuration task and simultaneously save as
Corresponding running status file；When command information is that running status recovers instruction, by running status file by type and lattice
Formula is recovered into the corresponding data area of controller, and the title for the status command meeting designated state file that resumes operation and road
Footpath.
On the basis of above-mentioned technical proposal, whether the decision instruction information effectively concretely comprises the following steps：Analysis instruction
The timestamp of information, judge the time difference between the timestamp and controller within the same cycle of operation.
Compared with prior art, the advantage of the invention is that：
(1) a kind of system for the access of nuclear power station DCS controller states of the invention, can be in system operation
Random time point receive preserve running status instruction, obtain Logical Configuration task running state data simultaneously store to corresponding
Running status file in.
Therefore the work condition state of multigroup Logical Configuration engineering can be pre-saved, operating mode is preset before saving different code debugging
The manpower and time cost of condition, simultaneously so that in the case where there is debugging task interruption, when can be from from interrupting nearest
Between point start to debug, avoid task from restarting, reduce debugging cost, shorten debugging cycle.
Brief description of the drawings
Fig. 1 is to be used for the structured flowchart that nuclear power station DCS controller states access system in the embodiment of the present invention；
It is used for the flow chart of nuclear power station DCS controller state access methods in Fig. 2 embodiment of the present invention.
