三菱梯形图转成51单片机HEX文件。 三菱软件写好梯形图，再运行转换软件，设定好51单片机的输入输出， 打开写好的梯形图，转换出的就是hex文件，烧录到51单片机，51单片机 就可以执行PLC的动作了。51单片机控制板价格便宜，可以代替简单场 合的PLC，控制成本降低。 1：把PWM转换后，在PWM文件下生成一个HEX文件。 2：生成的文件很大，51单片机要选用8K以上(AT89S52就是8K)储存量的。 3：把HEX文件下载到单片机就可以用了。 -Mitsubishi ladder into 51 single-chip HEX file. Mitsubishi software written ladder, and then run the conversion software, set 51 single-chip input and output, open ladder-written, conversion is a hex file, burn to 51 single-chip, 51 single-chip microcomputer can be implementation of the action of PLC. 51 Single-chip panel prices, can replace the simple occasions PLC, control and lower the cost. 1: after the PWM converter, PWM documents generated in a HEX file. 2: generate a lot of paper, 51 single-chip 8K to choose more than (AT89S52 is 8K) storage capacity. 3: The HEX file can be downloaded to a single-chip microcomputer used.
