The start/stop PLC method has the advantages that the equipment of the aggregate processing system can be started and stopped in an interlocking manner by the aid of a simple combination of bit logic instructions, instructions of timers and instructions of output coils, unexpected instantaneous power failure accident operating and responding abilities of the system can be guaranteed, the running safety of the system is greatly improved, and safety production of the aggregate processing system is guaranteed.
Description
Technical field
The present invention relates to PLC control method, the especially control of Preservation for Aggregate Production System equipment, belongs to PLC control technology field.
Background technology
In recent years, PLC(Programmable Logic Controller) control technology is more and more extensive in the application of large and medium-sized Preservation for Aggregate Production System, and PLC is simple with its programming, stable performance, the advantage such as easy to maintenance, has substituted the relay control mode in the past adopting.The core control section that PLC controls automatically as Preservation for Aggregate Production System, PLC program has determined the stability of whole system running to a great extent.The rational program design of logicality can make the production run of Preservation for Aggregate Production System safer, stablize.At present, most of Preservation for Aggregate Production System engineering projects are in the program design of PLC control system, adopt set-reset instruction to realize equipment interlocking start/stop function, in engineering application in the past, this program design often causes following accident to occur, once Preservation for Aggregate Production System runs into the situation of electrical network instantaneous power-off (several seconds～tens seconds), after electrical network instantaneous power-off is sent a telegram here again, after stopping, the most of equipment of sandstone system can start suddenly operation, because system loading is larger, distribution system is caused to great impact, there is unsafe factor simultaneously, personal safety is threatened.
Summary of the invention
For the problems referred to above, the invention provides a kind of PLC control method that combines to realize equipment interlocking start/stop with position logical order, timer instruction and output winding.
The technical solution adopted for the present invention to solve the technical problems is:
Preservation for Aggregate Production System equipment opens/stops PLC control method, comprises the following steps:
A.I0.0 connects, and PLC starts, and position input I0.1 connects, and 0.1 output of position storage command M keeps;
B. storage command M 0.1 in position is often opened a logical order connection, timer T1 time delay 10 seconds, and a position output Q4.0 connects, 2# sealing-tape machine S2# driver output, 2# sealing-tape machine S2# enters running status;
C. output Q4.0 in position often opens bit instruction connection, 2# sealing-tape machine S2# feedback, and a position input I0.2 connects, timer T2 time delay 10 seconds, an output Q4.1 output, 2# sealing-tape machine S2# is driven into operation;
D. when equipment stops, 1# sealing-tape machine S1#, 2# sealing-tape machine S2# feedback, position input I0.6, position input I0.2 connect, and 0.3 output of position storage command M keeps;
E.PLC stops automatically, and position input I0.5 connects, and often opens bit instruction M0.4 output and keeps;
F. often open bit instruction M0.4 and connect, timer T3 time delay output in 10 seconds, the normally closed bit instruction action of timer T3,1# sealing-tape machine S1# stops;
G. timer T3 often leaves bit instruction connection, timer T4 time delay output in 10 seconds, and the normally closed bit instruction action of timer T4,2# sealing-tape machine S2# stops.
The invention has the beneficial effects as follows, can guarantee system the ability of running reply burst instantaneous power-off accident, greatly improved the security of system operation, ensure that sandstone security of system produces.

Embodiment
Below in conjunction with embodiment, the present invention is further described.
Below taking Siemens S7-300 PLC and programming software STEP7V5.5 as basis, to realize the interlocked startup of 2# sealing-tape machine S2#, 1# sealing-tape machine S1# and hold function as example.
Referring to Fig. 1-5, Preservation for Aggregate Production System equipment opens/stops PLC control method, comprises the following steps:
A.I0.0 connects, and PLC starts, and position input I0.1 connects, and 0.1 output of position storage command M keeps;
B. storage command M 0.1 in position is often opened a logical order connection, timer T1 time delay 10 seconds, and a position output Q4.0 connects, 2# sealing-tape machine S2# driver output, 2# sealing-tape machine S2# enters running status;
C. output Q4.0 in position often opens bit instruction connection, 2# sealing-tape machine S2# feedback, and a position input I0.2 connects, timer T2 time delay 10 seconds, an output Q4.1 output, 2# sealing-tape machine S2# is driven into operation;
D. when equipment stops, 1# sealing-tape machine S1#, 2# sealing-tape machine S2# feedback, position input I0.6, position input I0.2 connect, and 0.3 output of position storage command M keeps;
E.PLC stops automatically, and position input I0.5 connects, and often opens bit instruction M0.4 output and keeps;
F. often open bit instruction M0.4 and connect, timer T3 time delay output in 10 seconds, the normally closed bit instruction action of timer T3,1# sealing-tape machine S1# stops;
G. timer T3 often leaves bit instruction connection, timer T4 time delay output in 10 seconds, and the normally closed bit instruction action of timer T4,2# sealing-tape machine S2# stops.
In above process, when 2# sealing-tape machine S2# driver output, feed back input all satisfy condition, 1# sealing-tape machine S1# could delayed startup.PLC program is in service, once there is instantaneous power-off accident, owing to adopting a position logical order, each equipment is because power-off does not have the feed back input of contacts of contactor, in new scan period of PLC program, can not cause the unexpected startup of equipment.
