Background technology
In industrial control field, need according to on-the-spot condition and the different controlling schemes of operational characteristic design for realizing control procedure.The process of access control scheme correctness, be that the physical quantity that the scene characterizes various characteristics is collected in the controller by input channel, and, be transported in the scene by output channel according to the different control program of feature establishment separately, drive topworks, thereby finished a control procedure.The correctness of control program, performed control is vital to controller, these control programs can be checked the correctness of its grammer when compiling, but the correctness of logic then need realize by other means.Yet, in the proving program logical process, always production run is caused disturbance, cause damage.Therefore controller need be reduced in the program verification process interference to production run, thereby reduces the loss, and raises the efficiency.
Controlling schemes in controller is made up of control section.Control section is to realize one section program of fixed function, and it has code and data, has characterized operation method, operating procedure and the operation result of program respectively.Permutation and combination by various control sections realizes different controlling schemes and control strategy.
Access control scheme correctness comparatively commonly adopts emulation technology.Emulation technology is exactly a simulated field ruuning situation, with the correctness of test controlling schemes.All kinds of emulation technologies emerge in an endless stream, the ruuning situation of these technology or simulated field, or with program run in emulation controller, importantly the input of program is also carried out the emulation input and output, isolated with on-the-spot gets in touch.Emulation technology to a certain extent can simulator program the situation of operation, find some problem of programmed logic, can not cause disturbance to the scene yet.
But because on-the-spot operating mode is Protean, setting up a correct simulated environment relatively wastes time and energy.If there is deviation in environment, just can't guarantee that program can adapt to actual field.Operate in the program of emulation controller for those, the signal of input is a simulate signal, exists certain difference with on-site signal, and the carrier of working procedure is not the environment of final operation.Because on-the-spot state is ever-changing, can not be comprehensive during design, if the problem that designing institute causes adopts this emulation mode to be difficult to detect, and the control program of one section logic complexity, its operation result is all linked with one another.If program has many places to make mistakes, emulation mode just can not be carried out the checking of follow-up interrelated logic, has found a mistake, must can carry out searching of next problem by update routine.Can not skip error routine, carry out the debugging of next section program, influence the debugging efficiency of system.
Along with being gradually improved of control technology, online download technology also moves to maturity, and when on-the-spot technology is improved, can adopt the method for online download usually, to reduce the influence to the equipment that runs well.These controlling schemes that obtain changing by online download need checking equally, if adopt emulation technology, need the simulation process before repeated plant is opened again, become inconvenient more on the contrary.Particularly when the input of newly-increased program be during certain data in the middle of the working procedure, old program roll back one time just can need be finished the whole debugging flow process of program again, process is loaded down with trivial details.
Therefore, for the improvement project of this class download, when debugging, the on-line debugging technology of employing, it forbids the operation of program segment by forbidding means.When program runs into the program segment of forbidding, skip the operation that this section program is carried out the next non-program segment of forbidding.This debugging method can be investigated program error, but can not debug the execution of program segment inside based on program actual motion environment on certain program.

Embodiment
For after the controlling schemes in the controller in the scene of solving changes, when new controlling schemes is debugged, can not be to the problem of its scheme implementation debugging.
The present invention proposes controlling schemes debugging technique based on the information flow shielding.In debug process, after shielding, realize this functional block debugging to the input traffic of functional block and output stream to controlling schemes.After debugging all functions piece of controlling schemes successfully, again controller is put in the work.Functional block among the present invention is meant control program is divided according to its logic, is divided into each program area.
Describe specific embodiments of the invention one in detail below in conjunction with accompanying drawing.
Referring to Fig. 1, the engineer station is connected with controller, and controller is connected with equipment in the factory.In the present embodiment, the engineer station is a terminal, when adding new controlling schemes or the controlling schemes moved when changing to the equipment in the factory, need carry out configuration to controlling schemes the engineer station, the process of configuration is with the instrument that provides in the application software, method, finishes the process of specific tasks in the control engineering.Configuration compiling forms new controlling schemes and downloads in the controller, debug qualified after, by controller shop equipment is controlled.
As other debugging method, the present invention need be provided with some special sign in program, need carry out some special processings when program runs into these signs.In a lot of high-level language programs these signs are called breakpoint, when the code line of carrying out these sign places is the operation of time out program.And the distinctive mark that is proposed among the present invention is different from breakpoint, and the present invention is referred to as to shield a little.When the program execution runs into the shielding point, skip the program segment that the shielding point is identified, carry out the operation of next section program.
The present invention logically carries out subregion by the method for shielding point is set with program, according to demand program is divided into a plurality of districts when debugging, and makeing mistakes in certain program area, can cut off this program area, carries out the debugging of next program area.Wherein, the particular flow sheet of embodiment is referring to Fig. 2,
Step S201: shielding is set in the program area characterizes point;
When the engineer station carries out the configuration compiling, shielding is set respectively in loading routine district, written-out program district, complicated process district characterizes point.The program that shielding characterizes in this program area of some expression can be skipped, and directly moves the program in the next program area.
Step S202: set up shielding and characterize point and the mapping table that shields point;
By Ethernet, mapping table is set up in the data field in the control program district the engineer station, the shielding of creating in each maskable program area is characterized point store in the mapping table, also will store and shield the corresponding shielding point of sign point in mapping table.The information of shielding point includes the pairing physical address in controller of this shielding point.
Step S203: the shielding point is set;
After will shielding the mapping table that characterizes point and shielding point and creating successfully, need be provided with shielding.When the shielding point that each complicated process district, loading routine district, written-out program district comprised is set, send the Ethernet order by the engineer station to controller, controller sends to the Ethernet data treatment region in the ethernet controller, controller carries out write operation by this order to the pairing physical address of shielding point, the storing value in this physical address is changed to opens or close.After being set to open, the pairing loading routine of this shielding point district, written-out program district or complicated process district can't move.
Referring to Fig. 1, in the present embodiment, maskable program area is 1 to N, and non-maskable program area is 1 to M.
Step S204: move each program area;
After mapping table is set up successfully, each state setting that shields point of needs shielding is finished, move each program area, there is shielding to characterize point, then execution in step S205 if find in the process of operation.
Step S205: judge the shielding dotted state;
In mapping table, find out this program and characterize the pairing shielding point of point, judge in the pairing physical address of shielding point to shield dotted state,, continue each program area of operation if closed condition is then returned step S204; If opening, then execution in step S206.
Step S206: debug the program in this program area.
Be transferred to the data test stage this moment, if what shielded is a loading routine district in the functional block, then during these functional block operation input data, can't go to gather measured value from signal input and output treatment region.Like this, protect the measured value that is not subjected to of this functional block to influence, can directly debug, assignment in functional block, and the output valve by this functional block detects this functional block whether in normal range.
When output valve after within the normal range, remove the shielding point again, the state that is about to the shielding point is set to close.The program of this functional block of operation realizes the control to equipment in controller.
