Chapter 3. Using the DCON Protocol

3.1 The feature of using DCON Protocol

The DCON firmware which uses ASCII Command provided with the 8430/8830/8KE4/8KE8, is easy to use and most of application can be developed using toolkits supported by ICPDAS, such as DLL, ActivateX or OPC Server, which can shorten their development time.
