switched on.
2.4.4 Setting the operating mode
With the DIL switch element 1.1 on DIL switch 1 the operating mode of the bus node is set.
Operating mode Setting DIL switch 1
Remote I/O operating mode
All functions of the CPX terminal are controlled directly by the
Sercos controller or by a superordinate PLC/IPC. The bus node
takes charge of connection to the Sercos III network.
1.1: OFF
(factory setting)
Remote Controller operating mode
An FEC or CEC integrated into the CPX terminal controls all
functions of the CPX terminal, i.e. the FEC or CEC undertakes the
I/O control. The bus node takes charge of connection to the
Sercos III network.

Please Note
The diagnostics mode reduces the available address space.
 When planning your CPX terminal, consider that the number of input and output bits
available for communication is reduced with usage of the diagnostic mode.
Subsequent activation of the diagnostics mode requires a reconfiguration.
 Observe that the CPX-internal I/O image can be displaced during subsequent activa
tion of the diagnostics mode.
 In this case, repeat the network configuration.

2.5 Connecting to the network
2.5.1 General notes about Sercos networks
Please Note
A Sercos network must always be structured as as ring or line topology.
For this reason, the use of hubs or switches is not permitted.
Please Note
Connecting a PC to the Sercos network (e.g. to use the bus node with the CPX-FMT soft
ware).
– With line topology:
 Connect the PC to the free port of the Sercos slave.
– With ring topology:
 Use a network tap suitable for Sercos.
Please Note
Sub-assemblies with Ethernet interfaces should only be operated in networks if all con
nected network components are supplied by PELV circuits or integrated power circuits
with equivalent protection.
Installation guidelines
Installation guidelines can be sourced from the Sercos user organization
(èhttp://www.sercos.org).
2.5.2 Overview of connection technology and network plugs
Note
Faulty installation and high transmission rates may cause data transmission errors as a
result of signal reflections and attenuations.
 Note wiring specification (èTab. 2.8).
Transmission errors can be caused by:
– faulty screened connection
– branches
– transmission over distances which are too long
– unsuitable cables.
Connection technology Network connectors
2 x M12 bush, D-coded, 4-pin, in accordance with
IEC 61076-2, SPEEDCON compatible

2.5.3 Cable specification
 Use sheathed Industrial Ethernet wiring of category Cat 5 or higher.
The bus node supports the “crossover detection” function (Auto-MDI/MDI-X).
To connect the bus node to the network or to a PC, this means you can choose between
patch cables or crossover cables.
The circuitry for network connections X1 and X2 is adapted automatically.
