4.1 Mounting
Note
Material damage due to incorrect mounting
Select screws that are suitable for the material of the interlinking block:
– Plastic: Thread-cutting tapping screws
– Metal: Screws with metric thread.
When ordering a single module, all required screws are supplied.
1. Check seal and seal surfaces. Replace damaged parts.
2. Push the module carefully and without tilting into the interlinking block up to the
stop.
3. Turn the screws into the existing thread.
4. Tighten the screws in diagonally opposite sequence. Tightening torque: 0.9 …
1.1 Nm.
4.2 Dismantling
5. Unscrew screws.
6. Pull the module without tilting out of the interlinking block.

Power supply
The operating and load voltage supply is fed in via the interlinking block

Remote I/O
All functions of the CPX terminal are controlled directly by the
Sercos controller or a higher-order controller.
DIL 1.1: ON
Remote controller
An FEC or CEC integrated into the CPX terminal controls all
functions of the CPX terminal.

– The setting of the operating mode via DIL switch 1.1 has priority over all
other settings.
– The switch element 1.2 is reserved and without function.

The diagnostics mode reduces the available address space.
Take account of this fact when planning the CPX terminal.

Parameterisation
Note
The CPX terminal and the module described here can be parameterised with the
operator unit (CPX-MMI), the Festo Maintenance Tool (CPX-FMT) software or the
higher-level system.
8
Note on module replacement
Caution
For CPX terminals with a continuously illuminated or flashing Modify LED (M),
parameterisation is not automatically created by the higher-level system when
the CPX terminal is replaced during servicing.
Before replacement, note required settings and make them again after re
placement.
9
Start-up behaviour of the CPX terminal
If the Modify LED (M) lights up or flashes permanently after the system start, “Sys
tem start with saved parameterisation and saved CPX expansion” is set or “Force”
is active.
Additional information on parameterisation, module replacement and
start behaviour of the CPX terminal can be found in the module descrip
tion (

P.BE-CPX-FB39-…).
