Ethernet Ports
CPE100 provides two independent Fast Ethernet LANs. LAN1 has only one port and is
dedicated to the embedded Ethernet controller. LAN2 is comprised of 3 switched
ports, each configurable either as a second embedded Ethernet controller or as an
embedded PROFINET controller. Use PME to configure the operation of the ports.
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, you first need to set a valid IP address.
CPE100
LAN1
LAN2
Default IP Address:
192.168.0.100

Subnet Mask:
255.255.255.0
0.0.0.0
Gateway:
0.0.0.0
0.0.0.0
Note:
•LAN2 will not be operational unless it is configured from the programmer with a valid
IP address.
•Care must be taken when assigning IP Addresses and subnet masks to each LAN so that
an overlapping IP subnet is not created. Intermittent or no Ethernet communication may
result if an overlapping IP subnet is created and the two interfaces are NOT connected
(cabled) to the same physical network.
•By default, PME prohibits configuring both LAN interfaces on an overlapping IP subnet.
(This may be changed by going to Controller General Options and changing the Multiple
Embedded LANs on Same Subnet to Show as Warning.)

Typical Network Application
A typical application will take advantage of the two independent LANs. The dedicated
LAN1 port will be used for communications with plant-level or supervisory layers. The
switched LAN 2 will be used to communicate with devices over PROFINET within the
manufacturing cell or process.

Module Start-up
Power-Up Time
The CPE100 requires at a minimum 35 to 40 seconds to complete power-up. When
power is applied, all the Ethernet Port LEDs blink once. When power up is complete,
the OK LED turns on and remains steady whereas the RUN LED indicates the current
run mode.
Whenever the internal super capacitors are completely discharged, the CPE100
might take approximately 105 seconds to complete the power-up sequence.
Typically, this occurs when the unit is without power for a few days.
You Will Need:
•This PACSystems standalone controller RSTi-EP CPE100.
•An external power supply 9-30 VDC provided by a Class II power
supply marked as "double insulated", Limited Power Source
(LPS), or a SELV source with a minimum 32 VDC listed fuse with
3 A max rating is required to power the CPE100.
•The 3-Way pluggable terminal block which is a mating
connector for the power input terminal block header located on
the front panel of CPE100 comes along with the package. This
mating connector accepts wire sizes 22 to 16 AWG. Screw
torque: 2 in-Ib. Temperature rating for copper wire: 80 °C.
Wiring should be stripped prior to connecting to the mating
connector and cannot exceed 30 m in length.

Programming the CPE100
To configure the CPE100, connect the computer running the PME programming
software to an Ethernet port of LAN1 using the default IP address 192.168.0.100. PME
9.5 SIM 1 or later is required.
Configuration will either start out using the RSTi-EP CPE100 template when creating
a new project or will convert an existing project to the CPE100 using the Family
Conversion feature in PME.
Backwards Compatibility
To convert an existing project which uses any other PLC, use the Family Conversion
feature in PME. Be aware of the constraints involved, as will be notified in PME. For
instance, the first PROFINET Controller in an RX3i CPU320 application will be assigned
to the embedded PROFINET Controller feature of the CPE100.
PROFINET Controller Configuration
An Embedded PROFINET Controller may be configured on LAN2. To enable the
PROFINET Controller in a CPE100 project, select the CPE100 target in the PME
Navigator (Figure 11) and open the Hardware Configuration.
On the Settings tab, change the LAN2 Mode of the selected port to PROFINET. The
PROFINET Controller node description then displays that a PROFINET node exists on
the selected LAN (under the CPE100). For further details, refer to the PACSystems
RX3i & RSTi-EP PROFINET IO-Controller User Manual, GFK-2571.
