Dynamic, make charger cylinder be heated to preheat desired temperature；Before machine to be fed, electronic scale has sent material signal, time delay a period of time
After, enter head material state, start and add water and front end charging electromagnetic valve and regulating loop；After time delay a period of time, material is full of whole again
Individual cylinder, system enters production status, starts front and back end charging electromagnetic valve and regulating loop, and before treating damping machine, electronic scale sends disconnected
Material signal, if the fracture time is shorter, charger enters head material state, if the fracture time is longer, then enters tailing state, and front end adds
Material stops, cylinder Accelerating running.After batch terminates, damping machine is automatically into preparing or the state of cleaning.Can by the flow chart of Fig. 1
Relatively complicated to find out the State Transferring of cylinder, particularly at the State Transferring of SBR, can according to different conditions
To be transformed into pre-Warm status, head material state and cleaning state.It is all according to different conditions that whole state controls process, selects one
The sequential control of definite sequence action.
Such as Fig. 2, a part for actual control program sectional drawing.The thinking using branching step carrys out sequential control application, according to
Different conditions selects different branches to carry out action executing, and the execution priority level of previous branch is higher than next branch.
Such as Fig. 3, roller equipment needs pause function, when equipment peripheral components breaks down when entering normal production status
When (such as disconnecting switch disconnection, air switch tripping operation, motor loop operation irregularity etc.) need to suspend, can be stopped by pause button
Live corresponding part automatically；Peripheral cell troubleshooting is complete, and suspend releasing is can to recover this auto-programming group at once
Automatically, this function is that Interlock is often walked by controlling the Interlock of each step interlocking condition realization
Individual condition able to programme, it affects the implementation status of each independent step.If interlocking condition (Interlock) meets, then with interlocking
The instruction of conditional combination will be performed；If interlocking condition is unsatisfactory for, then the instruction with interlocking conditional combination will be not carried out, with
Time interlocking rub-out signal will be 1.If interlocking condition is empty, the most not programming, system then thinks that interlocking condition meets.
Such as Fig. 4, equipment has needed to walk control command accordingly in each state, reaches under this state to equipment
Other system controls accordingly, in S7-GRAPH, it is provided that following control command is for programming personnel.
(1) order S；When step is movable step, output set is made to be 1 state and keep.
(2) order R: when step is movable step, make output be reset to 0 state and keep.
(3) order NC: when step is movable step, output is set to 1；When this step becomes inertia step, output is reset to
0。
(4) order L: be used for producing the pulse of restricted width, be equivalent to pulse timer.
(5) order CALL: be used for calling block, when this step is movable step, calls the block specified.
(6) order D: making the execution time delay of a certain action, delay time is arranged in the bottom-right square frame of this order.
Order NC and order L is employed in a large number in super roller equipment state controls.
Such as Fig. 5, after the source program programming that the state of equipment controls program terminates, can be in other functions of STEP7
Or in functional device calling corresponding GRAPH program, call method is as the call method of other programs, such as figure institute
Show.Must be noted that when calling concrete GRAPH program among these, must be corresponding for corresponding program name (such as FB100) same
The DB block (such as DB100) of sample, so can directly monitor when on-line monitoring, otherwise, due to sequence number and the DB of GRAPH program name
The sequence number of block is different, will need to check the name of DB block when monitoring every time.
