FB被CPU執(zhí)行的條件是必須是在組織塊（OB）中被調(diào)用，同時(shí)FB和FC也能實(shí)現(xiàn)子程序的嵌套。FB與FC的區(qū)別在與它們的變量聲明表中能夠定義的參數(shù)類型不同。當(dāng)FC的程序執(zhí)行完成后，F(xiàn)C的參數(shù)不能被保存；當(dāng)FB的程序執(zhí)行完成后，F(xiàn)B的參數(shù)能被保存。在OB1中調(diào)用FC時(shí)，只需直接調(diào)用，如：CALL FC1；而調(diào)用FB時(shí)，必須為其分配一個(gè)背景數(shù)據(jù)塊，用來(lái)保存FB的參數(shù)，如：CALL FB1，DB7。背景數(shù)據(jù)塊的數(shù)據(jù)格式與相應(yīng)FB的變量聲明表的數(shù)據(jù)格式相同，不允許用戶進(jìn)行修改。 用戶基本程序

PLC程序的編制全部按照正邏輯的設(shè)計(jì)，即不論物理信號(hào)是高電平還是低電平有效，邏輯“1"表示信號(hào)有效。所有物理輸入輸出信號(hào)都需經(jīng)過(guò)邏輯處理好，才能進(jìn)行邏輯運(yùn)算，也就是先要定義輸入輸出的信號(hào)有效和輸入輸出信號(hào)的邏輯，再將輸入輸出的物理信號(hào)和邏輯參數(shù)異或，其結(jié)果與有效參數(shù)（使能參數(shù)）與，后送入輸入輸出緩沖區(qū)中?，F(xiàn)就工作臺(tái)的運(yùn)動(dòng)控制為例加以說(shuō)明。

圓網(wǎng)印花機(jī)技術(shù)指標(biāo)procedures. This paper introduces the overall structure of the automatic cleaning machine, the working condition requirement, the hardware realization of the system and the thinking of the program design. This paper explains how to use PLC function to achieve automatic positioning of cleaning machine, automatic travel protection and other automatic processes, lists some important procedures. Introduction automatic cleaning machine is the company's production line on the important after-process processing equipment, the company mainly produces automotive engine internal products, products after the car, milling, after drilling and other multi-process, the surface is covered with a large number of dirt such as aluminum chips of cutting fluid. Such dirt must be cleaned before it can be assembled and packed. If manual cleaning is used, it will result in low efficiency, high labor intensity and can not realize automatic production, as well as product scratches, even scrap and so on. Because the company's cleaning machine is a special-purpose machine, there is no ready-to-buy product on the market, such as equipment factory custom-made, there will be long delivery time, affect the launch of new products on the market, high price, can not well meet the working condition requirements and other restrictions, in the above conditions, decided to make their own automatic cleaning machine. 2. GENERAL STRUCTURE OF AUTOMATIC CLEANING MACHINE GENERAL STRUCTURE OF AUTOMATIC CLEANING MACHINE: running system (running motor, driving device, positioning device of conveying position, conveying device, etc.) , water spray system, air jet system, electrical control system. The overall structure is shown in figure 1. The hardware part 1) the walking system is the key part of the automatic cleaning machine, its stability directly affects the reliability and continuity of the whole equipment operation. Because of the consideration of cost, the walking motor does not need stepping motor, but uses three-phase asynchronous motor produced by Beilun speed-regulating Motor Factory. The Motor has the advantages of power-off brake and reducer, reliable performance, small input power and large output torque. The conveyor belt adopts stainless
