GM8802数字变送器使用要求与注意事项
GM8802数字变送器使用要求与注意事项一、变送器与传感器相关参数1、变送器参数：GM8802是一款将0-10mv传感器模拟信号转换为0-10000数字信号的信号转换模块，工作电压为DC24V，激励输出电压为5V（即给传感器供5V电压）。
2、传感器参数：搅拌站所使用的称重传感器的信号类型为2mv/V，即激励电压为5V时，信号输出为0-10mv，激励电压为10V时(例如PLB-2E系列的模拟变送器)，信号输出则为0-20mv。
二、组网注意事项1、地址设置：GM8802采用RS485总线方式通讯，要求每个变送器具备唯一的节点号，可通过1-4号拨码进行调节。
节点号从1开始，采用“二进制值+1”的计算方式。
例如，4个拨码全部为OFF是，二进制为0000，“0+1”即表示1号节点；1、2号拨码为OFF，3、4号拨码为ON是，二进制为0011，“3+1”即表示4号节点，以此类推；同一通讯网络内不可出现节点号重复。
2、组网方式：RS485通讯应使用总线型组网方式，即首尾相连的连接方式，且通讯距离较长（300米以上加装，搅拌站通讯距离约为100米，一般可不加终端电阻）时，需在网络的两端分别安装120欧的终端电阻（跨接在RXD-A 、TXD-B 端子之间），以消除信号在线路中的反射效应，保证通讯的稳定可靠，如图1所示：120欧电阻120欧电阻(PLC图1：正确的组网方式图2：错误的组网方式3、电缆连接：GM8802通讯采用两芯双绞屏蔽线，模块有RXD-A 、TXD-B 、GND 三个接线端子，其中GND 是信号公共端，并不是真正意义上的大地。
不能将GND 端子与大地相连（不能使用黄绿端子），否则可能导致通讯中断或通讯缓慢！为提高信号传输的抗干扰能力，两芯双绞屏蔽线的屏蔽层须采取可靠地单端接地，且屏蔽层不与变送器的GND端子以及PLC的FG端子连接。
三、升级型号与旧款的区别为提升变送器的可靠性以及人性化操作，GM8802变送器于2013年8月进行了产品升级，升级后的型号未作改变，且功能上与旧款保持兼容，使用方法与旧款略有差别，对比如下：站类事业部电控开发所2013-8-30。

最终，虽然抱回家的是个名牌产品，但难免遇到其性能不及自己的期望、机型落伍等状况，要是再碰到一两个懂行伴侣“激情〞评价一番，那可真该算是“火上浇油、雪上加霜〞了。
家用摄像机市场的三大巨头——ＳＯＮＹ、松下、ＪＶＣ目前还是消费者的主要选择对象，尽管其他品牌也有同类产品，且在技术和价格上各有所长，但照旧没能在这一领域打破“三足鼎立〞的局面。

have two big-terms,F1and F2,and have several mini-terms under each big-item,the choice between item and item is used to go on;press the to go on the mini-term from big-item,and pressed the key

way;CONT:continual way.6.OperationWhen the instrument gets on power,it examines by oneself at first,the buzzer rings,the showing window mainly show and pair show flashes8,the state indicator lamp of the instrument glimmers at the same time.After examining and passing,the instrument goes into the normal working state, mainly show is the present weight value.When the weight value at present of the instrument changes the range in0±1/4d,the LED【ZERO】is on;When it changes in the steady range,the LED【STAB】is on;6.1The operation of zero clearingUnder the normal working state,press the key,it can do zeroclearing to the instrument(the weight showing at present should be within the zero clearing range,otherwise not do zero clearing).7.Serial portGM8802F batching controller has one serial port of RS232/RS485(chooses through the hardware switch within the instrument),in order to go to communication with munication way adopts the way of replying(namely the computer sends an order frame to instrument,after getting the order,the instrument returns a respond frame upward computer to realize communication),and also adopts the continual way(namely the instrument sends the weight data and the status data to the computer continually,do not get any order from the computer).7.1Serial modesPotter rate：1200、2400、4800、9600、19200、56700可选Available Byte form：Initial location---------1bitlong of

RS;F2.2is CONT.The instrument sends the data of weight and state continually from the serial port. The data form is as follow:STX State+/-DDDDDDD CRC CR LFAmong them:STX——Initial symbol(02H)State——M(4DH)Steady;S:(53H)Unstable;O:(4FH)Overflow+/-——Symbol，+（2BH）-（2DH）DDDDDDD——7bits of weight including decimal point,the highposition is in front.R——（52H）S——（53H）CRC——Sum of the value of check-up.All its number value summation in the front is changed into the decimal system in the check-up,then fetch the last two and transfer to ASCII.CR——(0DH)Returning symbolLF——(0AH)Sign that change a new line7.2.2Ordering way that under RS communication formIn working parameter setting up,F2.1is RS;F2.2is READ.The data form is as follow:T he computer reads the state of the instrumentSTX Addr.R S CRC CR LFAmong them:STX——Initial symbol(02H)Address——Number of the balance,2bits;If the number of the balance is 01,that is30H31HR——（52H）S——（53H）CRC——Sum of the value of check-up.All its number value summation in the front is changed into the decimal system in the check-up,then fetch the last two and transfer to ASCII.CR——(0DH)Returning symbolLF——(0AH)Sign that change a new lineFor example:When reading the state of the No.2balance,the data form that it sends is:023032525336350D0AThe instrument’s responding:STX Addr.R S000State DDDDDD CRC CR LFAmong them:STX——Initial symbol(02H)Address——Number of the balance,2bits;If the number of the balance is 01,that is30H31HR——（52H）S——（53H）000——3bits（30H30H30H）State——M(4DH)Steady;S:(53H)Unstable;O:(4FH)OverflowDDDDDDD——Mainly show value(6bits),if the value is negative thenthe high position is negative.For example,the mainly show of the instrument is-1.345,then,that is2DH30H31H33H34H35HAmong them,2DH is mean negative.the mainly show of the instrument is1.345,then,that is30H30H31H33H34H35HCRC——Sum of the value of check-up.All its number value summation in the front is changed into the decimal system in the check-up,then fetch the last two and transfer to ASCII.CR——(0DH)Returning symbolLF——(0AH)Sign that change a new lineThe data form of state returning:0230315253303030532D303331343834340D0AIt means the present state of No.1balance is:the instrument is in the unstable state,mainly show shows-3148Reading the decimal pointSTX Addr.R P CRC CR LFSTX——Initial symbol(02H)Address——Number of the balance,2bits;If the number of the balance is 01,that is30H31HR——（52H）P——（50H）CRC——Sum of the value of check-up.All its number value summation in the front is changed into the decimal system in the check-up,then fetch the last two and transfer to ASCII.CR——(0DH)Returning symbolLF——(0AH)Sign that change a new lineFor example:Data form that send an order of reading the decimal point to the instrument:023031525036310D0AThe instrument’s responding:STX Addr.R P DDDDDD CRC CR LFAmong them:STX——Initial symbol(02H)Address——Number of the balance,2bits;If the number of the balance is 01,that is30H31HR——（52H）P——（50H）DDDDDD——000000～000004,Correspond0,0.0,0.00,0.000,0.0000。
