1 Use for intended purpose
The module described in this document is intended for use as a participant in net
works with the protocols EtherNet/IP or Modbus TCP in an industrial environment.
The module is intended exclusively for use in CPX terminals from Festo for installa
tion in machines or automated systems and may be used only in the following
ways:
– in an excellent technical status
– in original status without unauthorised modifications, except for the adapta
tions described in this documentation
– within the limits of the product defined through the technical data.
Outside of industrial environments, e.g. in commercial and mixed-residential
areas, actions to suppress interference may have to be taken.
You will find detailed information in the following documentation:
– Description on the module (èCPX-FB36-…)
– CPX system description (èP.BE-CPX-SYS-…).
EtherNet/IP®, MODBUS®, SPEEDCON®are registered trademarks of the
respective trademark holder in certain countries.
2 Safety
Before assembly or installation work, switch off the power supply, switch off the
compressed air supply, exhaust any pneumatic components.
For the electrical power supply, use only PELV circuits in accordance with
IEC 60204-1/EN 60204-1.
Observe the handling specifications for electrostatically sensitive devices.
Seal unused connections with cover caps to achieve the required degree of
protection.
Use connection hardware with the required degree of protection.
Observe specifications in the description for the module and the CPX system
description.
Place only a completely mounted and wired CPX terminal into operation.

3.1 Network connections
There are two 4-pin, D-coded M12 sockets on the bus node for the network con
nection. The sockets are compatible with SPEEDCON plugs. Both connections have
Auto-Negotiation and Crossover Detection (factory setting).
When crossover detection is activated, the bus node automatically
exchanges the transmitted and received data.
If Crossover detection is deactivated, assignment of the pins for transmit
ted and received data at the XP2 connection is crossed. As a result, several
bus nodes in a row can each be connected with a patch cable.

3.2 LED indicators – normal operating status
Behaviour of the LED indicators in normal operating status:
– The green LEDs [PS], [PL], [MS] and [NS] are illuminated.
– The green LEDs [TP1] and/or [TP2] light up or flash.
– The red LED [SF] is off.
The yellow LED [M] lights up only when “System start with saved paramet
erisation and CPX extension” is set.
