    NETLink Switch can be installed in any position. Minimum clearance Minimum clearances must be observed because • Then it is possible to insert and remove NETLink ® Switch with- out having to remove other system components. • There is enough space to connect existing interfaces and other contacts using standard commercial type accessories.

  • Page 11: System Overview

    Switch with the pro- ® grammable controller is to be connected to the front of NETLink Switch. In case of a branch line it is to be executed actively (acces- sories, see chapter 3.5). When a node is integrated in the bus, the connection can be carried out via a common PROFIBUS plug (ac- cessories, see chapter 3.5).

    Any value between ‘0’ and ‘31’ can be specified for the station ad- dress if this address does not yet exist on the bus. The local timeout of the NETLink-S7-NET driver can be param- eterized in the station-related settings. If the driver does not re- ceive a response to a request within the set timeout, a communi- cation error is signaled to the Simatic application.
