7.5  Configuration with SILworX - CPU OS V7 and Higher 
This chapter describes how to configure communication using SILworX for processor operating 
systems V7 and higher. 
Depending on the application, the following elements must be configured: 
  Ethernet/safeethernet. 
  Standard protocols 
Refer to the SILworX communication manual (HI 801 101 E) for more information on how to 
configure the standard protocols. 
7.5.1  Configuring the Ethernet Interfaces 
Ethernet interfaces are configured in the Detail View of the communication module (COM). If the 
remote I/Os have no communication module, the Ethernet interfaces are configured in the Detail 
View of the processor module (CPU). Refer to the manuals of the HIMatrix systems for more 
details. 
SILworX represents the processor system and the communication system within a device or 
module as processor module and communication module. 
For HIMatrix systems, set the Speed Mode [Mbit/s] and Flow Control Mode to Autoneg in the 
Ethernet switch settings. 
The parameters ARP Aging Time, MAC Learning, IP Forwarding, Speed [Mbit/s] and Flow 
Control are explained in details in the SILworX online help. 
Replacement of one controller with identical IP address: 
If a controller has its ARP Aging Time set to 5 minutes and its MAC Learning set to 
Conservative, its communication partner does not adopt the new MAC address until a period 
of 5 to 10 minutes after the controller is replaced. During this time period, no communication is 
possible with the replaced controller. 
The port settings of the integrated Ethernet switch on a HIMatrix resource can be configured 
individually. In the Ethernet Switch tab, an entry can be created for each switch port. 
In F*03 controllers, VLAN is available and allows one to configure the connection of the ports to 
CPU, COM and one another. VLAN is important for proper configuration of redundant 
safeethernet.
