Communications Programs (SYSMAC C200HX/HG/HE PCs)Chapter 7
Note In this chapter, the bits, words, and data memory used in the ladder pro- grams are selected at random. When creating actual programs, modify the contents so that they do not overlap with other areas.
7-1 Standard Remote I/O Programming
When the following standard remote I/O programming is executed, the rotational speed reference data specified in the DM (Data Memory) Area of the PC is written to the 3G3FV Inverter and forward or re- verse operation is performed at the specified frequency when the Frequency Reference Input Bit is turned ON and the Forward Input Bit or Reverse Input Bit is turned ON.
