Ethernet Ports
CPE100/CPE115 provides two independent Fast Ethernet LANs. LAN1 has only one port and is dedicated
to embedded Ethernet controller and whereas LAN2 is comprised of 3 switched ports configurable either
as a second embedded Ethernet controller or as an embedded PROFINET controller.
All the Ethernet ports of both the LAN1 and LAN2 are capable of automatically sensing the link data rate
(10 Mbps or 100 Mbps), communications mode (half-duplex or full-duplex), and cabling arrangement
(straight-through or crossover).
To establish Ethernet communications between the PME programming software and the
CPE100/CPE115, you first need to set a valid IP address.
Note: LAN2 will not be operational unless it is configured from the programmer with a valid IP
address.
The programming software 'Proficy Machine Edition' uses SRTP (Service Request Transport Protocol), a
proprietary protocol used primarily for communication with the controllers. The Ethernet port of LAN1
can be used to communicate with the PME software and is also a recommended option. Alternatively,
any port of LAN2 can also be used but first it should be configured with a valid IP address. Ethernet ports
of LAN2 can also be configured to be used as either a second embedded Ethernet controller or as an
embedded Simplex PROFINET I/O Controller.
