PACSystems PROFINET Managed Industrial Ethernet Switches User Manual
GFK-3030
Ethernet Devices on an Ethernet Network
The GLM switches contain a number of features which cannot be accessed over PROFINET, but are available
over Ethernet. The user may choose to install a separate Ethernet network for this purpose, or run both
PROFINET and Ethernet on the same physical network. Refer to Appendix B,
Caution
Care needs to be taken that connection to an Ethernet networks does not expose
the application to outside interference or monitoring, and does not impose heavy
traffic on the PROFINET network, which is intended to service IO-Devices in a timely
manner. Refer to the
PACSystems RXi, RX3i, RX7i and RSTi-EP Controller Secure
Deployment Guide,
GFK-2830.
Within the RX3i, the user may install an ETM001 module in a rack controlled by the host PLC CPU, or may use
an embedded Ethernet port within the CPU itself to provide the Ethernet features. .If none of the Ethernet-only
features will be used, no dedicated Ethernet function is required.
The following features, which are outside the scope of this manual, may be accessed over Ethernet, but may
not be accessed over PROFINET:
•
Virtual LANs (VLANs)
•
Access Control List Security (ACL)
•
Quality of Service (QoS) features
•
