| 摘 要： | 触摸屏内部通常可以识别各种型号PLC,用户在触摸屏软件中可以直接针对PLC的变量地址进行读写编程,但是触摸屏和PCC产品的兼容无法像PLC那样简单,针对此问题介绍了如何通过Modbus通讯协议使HITECH触摸屏监视和修改PCC的变量数据.解决方案的提出不仅解决了PCC和HITECH触摸屏相搭配的数据交换问题,同时更为PCC的用户提供了一种编程思路和设计方法.

| Abstract: | Usually,the type of PLC could be identified by touch screen,so touch screen can read and write data directly toward variable address of PLC.Because of the complexity about compatibility between touch screen and PCC,a scheme which could implement that HITECH touch screen monitor and modify variable data in PCC according to Modbus communication protocol was introduced.The scheme not only settles the data exchange between PCC and HITECH touch screen,but also supplies new program idea and design method to users... |
