西门子PLC基本指令功能介绍
一、标准触点 LD、A、O、LDN、AN、ON、 LD，取指令。表示一个与输入母线相连的常开接点指令，即常开接点逻辑运算起始。 LDN，取反指令。表示一个与输入母线相连的常闭接点指令，即常闭接点逻辑运算起始。 A，与指令。用于单个常开接点的串联。 AN，与非指令。用于单个常闭接点的串联。 O，或指令。用于单个常开接点的并联。 ON，或非指令。用于单个常闭接点的并联。 二、正、负跳变 ED、EU ED，在检测到一个正跳变（从OFF到ON）之后，让能流接通一个扫描周期。 EU，在检测到一个负跳变（从ON到OFF）之后，让能流接通一个扫描周期。 三、输出 = =，在执行输出指令时，映像寄存器中的指定参数位被接通。 四、置位与复位指令S、R S，执行置位(置1)指令时，从bit或OUT指定的地址参数开始的N个点都被置位。 R，执行复位(置0)指令时，从bit或OUT指定的地址参数开始的N个点都被复位。 置位与复位的点数可以是1-255，当用复位指令时，如果bit或OUT指定的是T或C时，那么定时器或计数器被复位，同时当前值将被清零。 五、空操作指令NOP NOP指令不影响程序的执行，执行数N（1-255）。 福州卓凯电子科技有限公司联系人：小林 24小时咨询热线：17705012279 电话：0591-22983857 联系QQ：879520885 传真：0591-22989937 公司主营产品有：AB,ABB,GE,西门子,力士乐，施耐德,福克斯，等工业自动化控制配件及各种停产备件。诚信经营，质量可靠，请放心购买，我们将竭诚为您服务！ TDK RMX 24-C POWER SUPPLY KEPCO 24 VOLT OUTPUT TEC SIS 99-3453-1100 SERIAL 125403 LOAD CELL TENSIONMETER 50LB W/SAFE GUARD TEC SIS LOAD CELL TENSIONMETER 50LB W/SAFE GUARD TEC TECHNOLOGY FOR ENERGY 504A CHARGE CONVERTER TECAN 10 612 513 LIHA DISPOSABLE TIPS CONDUCTIVE 1000UL BOX OF 768 TIPS TECHNI-STAT TECHNI-TOOL 709ST300 IONIZING AIR BLOWER 435WATT *MP 115VAC 50/60HZ TECHNOLOGY FOR ENERGY CORP TEC MODEL 164 ALARM 1674-1-1 TECHNOVA BFVB2DN100 4" BUTTERFLY VALVE LOCKING LEVER HANDLE 8 THREAD HOLES TECHNOVA BFVB2DN80 3" BUTTERFLY VALVE LOCKING LEVER HANDLE 8 THREAD HOLES TEFLON MANIFOLD TEGAL 40-140-003 CERAMIC SHOWER HEAD SHOWERHEAD RING TEGAL 40-395-003B CERAMIC RETAINING RING 4" TEKEI TKW3632505SDP INCREMENTAL ENCODER TEKMAR 14-4619-090 REV E INTER CONNECT PWB (7000) VARIAN T1 446190 90 TEKTRONIX 020-2188-00 P6112 PASSIVE VOLTAGE PROBE 10X TEKTRONIX 3 COLOR TRANSFER ROLL 016-1262-00 TEKTRONIX DC 5009 UNIVERSAL TIMER COUNTER FREQUENCY 135MHz DC5009 PLUGIN TEKTRONIX P6137 PASSIVE VOLTAGE PROBE TEKTRONIX P6201 ACTIVE FET PROBE ATTENUATOR HEADS CASE TEKTRONIX TDS410A DIGITIZING OSCILLOSCOPE WORKING GUARANTEED TEKTRONIX TDS540 DIGITIZING OSCILLOSCOPE FOUR CHANNEL INSTRUMENT TEST MEASUREMEN TEKTRONIX TLA 510 LOGIC ANALYZER, 100 CHANNEL, 100 MHZ TEKTRONIX TLA 7N4 LOGIC ANALYZER OPTION 6S 136 CHANNEL TELEDYNE 605237003 COMBIFLASH 4X COMPANION EXPANSION MODULE FLASH CHROMATOGRAPHY TELEDYNE ANALYTICAL INSTRUMENTS MODEL 3000 BACK PAN TELEDYNE BROWN ENGINEERING A 9309 ALARM COMPARATOR BOAR TELEDYNE BROWN ENGINEERING B2422* PCB TELEDYNE BROWN ENGINEERING B30868 PROPORTIONAL TEMP TELEDYNE BROWN ENGINEERING B30927 PCB TELEDYNE BROWN ENGINEERING MODEL 3000 FRONT PANEL DISPLAY ASSY P/N C62371 TELEDYNE DV-4D-VCR THERMOCOUPLE VACUUM GAUGE TUBE TELEDYNE ISCO 60-5234-024 NORMAL PHASE COLUMN FOR FLASH CHROMATOGRAPHY TELEDYNE ISCO 69-2203-324 NORMAL PHASE DISPOSABLE COLUMNS 24 GRAM REDISEP RF TELEDYNE ISCO 69-2203-410 C18 2 REVERSE PHASE COLUMN 4.3 GRAM REDISEP RF TELEDYNE ISCO OPTICAL UNIT TYPE 11, PART # 601140002 TELEDYNE MICROWAVE R90-088-072 FLEXIBLE CABLE TYPE N -
