[Sample 3]

Network consists of EHV-CPU and Web controller as follows, and the Control Editor sets the ASR communication of

EHV-CPU. ASR communication of Web controller is set using the Web browser. The setting information of

EHV-CPU4 and Web controller is as follows.

The connection is established between EHV-CPU4 and Web controller in two seconds later after RUN of EHV-CPU4,

16-word data from WR0 to WRF of EHV-CPU4 is transmitted from EHV-CPU to Web controller at one second

interval. In Web controller, the received data is stored in WR0 to WRF. And 16-word data from WR10 to WR1F of

Web controller is transmitted from Web controller to EHV-CPU4, and the received data is stored in WR10 to WR1F

in EHV-CPU4.
