Interference in industrial control software program

The data for errors caused by the stack is destroyed possible. RAM area for the recovery of the approach in different application systems should be based on the specific situation of choice. 6 Control measures in the state of abnormal conditions of the software control system, the question is whether people's attention to ensure the normal control state. If the interference into the system, it will affect a variety of controlled conditions, resulting in control of the output errors. To ensure system security software can take the following anti-jamming measures. 6.1 software were the conditions of redundant control system, a sampling control conditions, process control output, to loop sampling, process control output. This method is great for the inertia control system has good resistance to accidental factors interfere. 6.2 set the current output state storage unit when the output channel interference caused by invasive damage output state, the system can query the current output state in time the output of status information storage unit, in a timely manner to correct the output state. 6.3 Setting the system self-test program on the computer or some specific portion of the state flag memory cell located in the continuous cycle of testing operation to ensure that the system information storage, transmission, operation of high reliability. 7 Conclusion (continued on page 23) such as dust Xiao Department of Computer stitch burning oyster plant bore five with 23RUNFCHK2OPENCLOSlFll74.4183.075.375.4Segment1NameICHK86ETvDecltPSI/Q/D/B/T/C, lDecl: CSI / Q / D / B / T / C, lDecl: AUToI / Q / D / B / T / C: lDecl: ALAMI / Q / D / B / T / C; lDecl: FAULIIQID / B / T / C, lDecl: DB-UI / Q / D / Bfr / c; BDecl: SWIIQID / B / T / C: lDecl: RUNZ1/Q/D/B/T/C; lDecl: CHK1IIQID/B/T/C, lDeclzRUNFIIQID / B / T / C ; lDecl: CHK2I/Q/D/B/T/C: lDecl: OPENI / Q / D / B / T / C: lDeclCLosI / Q / D / B / r / C: l4 the conclusion of the sintering plant level control system already leading in the country, its debugging success for the future management of the centralized control of large multi-sintering plant dust Taipower provides a model system.

(Continued from page 12) iron ore produced by the country's quality of view, as long as the finely ground, deep selection can satisfy the technology of pellet production requirements. And some of mine also has a special metallurgical properties, such as vanadium-titanium magnetite concentrate pellets. It should also be emphasized is. \powder, is very unfavorable to the smelting process. which are now rare in the domestic and international promotion.
