Project parameter/demand/solution
As for HCB that, a unified automatic control concept and a complete standardized automatic control constitution is extremely important. The high usability, the security, the easy start, the easy maintenance as well as the wrong diagnosis ability is this concept important constituent.

The signal is transmitted through the very long distance and must pass through some high electromagnetic radiations areas for example to approach the converter the place. In shaft also
The existence is struck by lightning danger. Company's network topology is composed by several optical fiber rings and some star webpages. The data output rate is 187.5 Kbits/s to 1.5 Mbits/s. because of the security aspect reason, the redundancy is extremely important.

After the breakdown occurs, OZD the Profi equipment produces a failure report immediately and carries on the transmission through the network. Had like this prevented the operation severance, has guaranteed the error correction actual effect.

Selects the Hess graceful product the reason
The following factory should choose and Si's graceful product:
. Possibly selects annular, the star, the main line topology, may carry on the redundancy disposition
After. needs the breakdown to report to the police the fast breakdown localization and processing
. The installment is simple, because the Rail series product is the guide rail type installment
. The start fast is simple
. Strong and compact design
. The working life is long
