VB MODBUS RTU complete
no vote
The communication protocol of Modbus RTU can be regarded as an industry standard protocol in fact, which is supported by many intelligent control devices such as instruments and PLC. KDN-K3 series PLC is independently developed by Beijing kaidean company. On the other hand, IEC61131 international standard is internationally recognized as the most adaptable PLC software model. All major international companies have recognized this standard and joined the open PLC organization to promote IEC61131 standard. However, due to its commercial interests, it is not willing to give up its original style completely, and the product conversion is not thorough. KDN-K3 series PLC software system from the beginning of the design is fully in line with the IEC61131 standard defined software model, for the subsequent development of the product has laid a solid foundation. Based on the consideration of supporting domestic PLC and IEC61131 international standard, although we have no relationship with cadion company, we still introduce the communication demo program of knd-k3 series PLC programmed by VB, hoping to give you some help and get some inspiration when compiling similar communication program.
