WIN2000 IPv6 Configuration 3: test network connectivity
In Windows NT operating systems, one network adapter can correspond to multiple interfaces), one interface corresponds to an ipv6 address, and the same applies to Windows 2000 Server. Therefore, when a network adapter usually has multiple ipv6 addresses, there must be at least a local link address, usually a site address, a global address, and a transitional address from ipv4 to

What is Modbus protocol?
What isModbus?Modbus is the first soft communication protocol proposed by modicon.Is gradually recognized as a standard communication protocol.Data communication or transmission, different systems can communicate. Currently, during RS232/RS485 communication,This Protocol is widely used.There are two common Modbus communication protocols: Modbus ASCII and Modbus RTU.Generally, the Modbus ASCII protocol is used for communication with a small amount of comm
After hard exploration, the configuration-driven development is finally integrated (maybe so, self-feeling). At present, we have completed all the ioserver design, using both com and TCP communication channels, you can develop a large number of device drivers. The following is a brief introduction:

Protocol Structure
This section describes the general formats of Modbus requests and response encapsulation carried by Modbus/tcp networks. Note that the structure of the request and response body (from the functional code to the end of the Data Section) has the same layout format and meaning as other Modbus variables, such: modBus serial port-ASCII encoded ModBus serial port-RTU (Binary) encoded Modbus plus network-data tunnel these other cases ar
