Private NetworkThe Private Network has a static configuration with IP address 192.168.125.1/24and hosts a DHCP server. The purpose of the Private Network is to connect thecomputers within the robot controller as well as I/O networks and process equipmentlocal to the robot. Many IP addresses are reserved on this network, so it isrecommended that new units get their IP address from the DHCP server.NoteNever connect another DHCP server to any of the ports connected to the PrivateNetwork. There cannot be two DHCP servers on the same network. It might causean erroneous behavior of both internal and external units.Ability NetworkConfiguration of the IP settings for the Ability Network shall be done manuallywhen the controller is equipped with a wired Connected Services Gateway(DSQC1041) that is connected to an Internet gateway, using an IP address providedby the network administrator.NoteOn OmniCore E line controllers, the WAN2 port is equivalent to a wired ConnectedServices Gateway (DSQC1041).The IP address configuration is done either in RobotStudio or on the FlexPendant.As an exception to the reserved ranges mentioned in section Reserved IP addresseson page 81, the Ability Network is allowed to configure IP addresses within thereserved range 192.168.126.0 - 255, but not within 192.168.125.0 - 255 or192.168.127.0 - 255.For security reasons, only outbound access on port 53 DNS and 443 HTTPS areallowed. The inbound access is blocked by an internal firewall and cannot beunblocked.NoteFor more information about connecting the Ability port to the internet, seeApplication manual - Controller software OmniCore.Public NetworkThe Public Network interface is typically connected to the factory network with apublic IP address provided by the network administrator. The Public Networksegment can be used for:• Connecting a PC running RobotStudio. For more information see Operatingmanual - RobotStudio.• Mounting FTP or NFS disks from the controller.• Running Industrial Ethernet protocols.Most protocols are disabled by default in the controller firewall. See Firewall settingson page 84 for information about how to enable these protocols.Continues on next page82 Product manual - OmniCore E103HAC079399-001 Revision: C© Copyright 2019-2022 ABB.
