What is VxComm Technique?
"VxComm" stands for "Virtual Communications Ports".
The VxComm Driver creates COM port(s) and maps them to the ethernet port(s) of the 7188E/8000E controllers. The user's RS-232 client programs only need to change to different COM ports to gain access to serial devices over Internet or Ethernet networks via the 7188E/8000E controllers.
What is SCADA?
SCADA stands for Supervisor Control And Data Acqusition. It is a production automation and control system based on PCs.
It is widely used in many fileds like power generation, water systems, oil, chemistry, and automobile industries. Different fields need different functions, but they use the following features:
When you buy an I-7188E -MTCP controller, it already has the default Modbus firmware installed in Flash memory. The default firmware has the follows features:
