AO845A-eA输入模块,3BSE045584R2中文说明
MODBUS RTU地址与GForce-200的地址对应关系 MODBUS地址总是以00001、30004之类的形式出现。GForce-200内部的数据存储区与MODBUS的0、1、3、4共4类地址的对应关系如附表所示: 附表 MODBUS地址对应表说明:其中T为GForce-200中的缓冲区起始地址，即HoldStart。如果已知GForce-200中的V存储区地址，推算MODBUS地址的公式如下: MODBUS地址=40000+(T/2+1) 其中T为偶数。
AO845A-eA输入模块,3BSE045584R2中文说明5 结束语 Modbus RTU作为一种工业控制器的网络通讯协议，其在如今众多的控制器之间进行联网、监控、相互通讯等方面发挥着重大作用，本文以典型的GForce-200控制系统为例，详述了如何应用Modbus RTU通讯协议以及检测方法，使得控制器之间的通讯变得更加简易和清晰。 系统组成
2.1 TDAM系列数据采集终端
TDAM7018模块包括8个输入通道,CPU采用ARM 32位处理器，AD采用24bit实现模拟数字转换，运算能力强大， RMS 噪声为5 μV ,零点偏移小于20 μV。每个数据采集器在板上带有一个稳定的参考电压,采用多重积分算法确保在任何环境下不需额外考虑就可得到精确测量
2.1 通信隔离模块
隔离器用来将数据采集器的数据电缆通过串行口接入PC主机,即将数据采集器的RS485信号转换PC主机所需的RS232信号,隔离器也将系统与主计算机进行了电隔离。
2.3高精度温度传感器
a) 0-1200℃部分采用铠装型K型热电偶探头，实现防腐 防酸碱性；延长线采用台湾进口耐高温不锈钢网线，实现信号的长距离传输。固态硬盘,宽温硬盘,高速硬盘,电子硬盘,数据存储卡,工业SSD固态硬盘1、HDD Hard Disk Drive的缩写，即硬盘驱动器的英文名。最基本的电脑存储器，我们电脑中常说的电脑硬盘[C盘、D盘为磁盘逻辑分区]都在硬盘驱动器中。硬盘一般常见的磁盘容量为40G、80G、120G、160G等等，目前最高的桌面级硬盘为2TB。硬盘按体积大小可分为3.5寸、2.5寸、1.8寸等，按接口可分为PATA、SATA、SCSI等，PATA、SATA一般为桌面级应用，容量大，价格相对较低，适合家用；
curve recording of programming software, and third-party general wave recording software. Variable recording of HMI Software (also referred to as SCADA software) is to add all variables to be recorded in HMI and set them to continuous recording, and then use waveform viewing control to playback waveform. This method is extremely inconvenient for temporary fault detection, because it is necessary to stop the HMI screen for screen development, and then run it again. The workload is not small, and it affects the use of operators. In addition, the variable refresh speed of HMI is generally low, such as 0.5s refresh cycle, and the program execution cycle of PLC is generally within 100ms. Therefore, many details will be omitted.
Not many PLC programming software can record curves, and it is not easy to operate. For example, STEP7 cannot record the curve. Botu has the track function (limited to s7-1200, s7-1500, etc.), but its essence is to record in PLC and then upload the display. The advantage: it can realize the recording of each cycle.
