Instructions on this documentation
Note
This description refers to the CPX bus node type CPX-FB23 from Revision R14 (CC-Link
version 1.1) and type CPX-FB23-24 from revision R22 (CC-Link version 1.1 and 2.0).
For corresponding specifications, see name plate.
This description contains specific information on installing, commissioning, programming and diagnost-
ic with the CPX bus node for CC-Link.
The CPX bus node type CPX-FB23-24 supports either the CC-Link versions 2.0 and 1.1.
Because of the fundamental differences between protocol versions 2.0 and 1.1, the correspondingly
configured bus node is either designated as a function module F24 (CC-Link version 2.0) or as a func-
tion module F23 (CC-Link version 1.1). These designations are found, for example, in the system of
representation of the Maintenance Tools (CPX-FMT) or handheld (CPX-MMI) from Festo.
– CC-Link version 2.0 corresponds to the function module F24 and supports up to four stations per
slave with extended address space. It is possible to configure the addressing either cycle-time or
station optimised.
– CC-Link version 1.1 corresponds to the function module F23 and supports up to four stations per
slave address up to a volume of 32 byte inputs and outputs.
Product identification, versions
–Inchapters 2 to 4 the behaviour and operation of the bus nodes is described
CPX-FB23-24 in the configuration F24.
– The corresponding information on bus nodes is found CPX-FB23 in the CPX-FB23-24
configuration F23, summarised in Chapter 5.
General information on the fieldbus CC-Link is found in the documentation for your CC-Link master and
for the relevant control systems (e.g. from Mitsubishi). An overview can be found under
www.cc-link.org.
General basic information about the mode of operation, assembly, installation and commissioning of
CPX terminals can be found in the CPX system description (P.BE-CPX-SYS-…).
Information about additional CPX modules can be found in the description for the respective module.
Service
Please consult your regional Festo contact if you have any technical problems.

2 Installation as function module F24
The instructions and descriptions for assembly in this chapter with exception of
section 2.4.8 are valid also for the configuration as a function module F23.
For the function module F23 is valid instead of the section 2.4.8 of the section 5.2.1.
2.1 General instructions on installation
Warning
• Before carrying out installation and maintenance work, switch off the following:
– compressed air supply
– operating voltage supply for the electronics/sensors
– load voltage supply for the outputs/valves
In this way, you can avoid
– uncontrolled movements of loose tubing
– accidental movements of the connected actuator technology
– undefined switching states of the electronics
Caution
The CPX bus node for CC-Link contains electrostatically sensitive devices.
• Therefore, do not touch any components.
• Observe the handling specifications for electrostatically sensitive devices.
They will help you avoid damage to the electronics.
Note
Handle all modules and components with great care. Pay particular attention to the
following:
– Comply with the specified torques

The CPX bus node is installed on an interlinking block of the CPX terminal (Fig. 2.2).
Warning
Mounting /dismounting of the bus node must always take place in a de-energised state.
• Disconnect the corresponding CPX terminal completely from the related voltage
supply or switch it off.
2.3.1 Dismounting
Dismantle the bus node as follows:
1. Loosen the 4 screws of the bus node with a
Torx screwdriver size T10.
2. Pull the bus node carefully and without tilting
away from the contact rails of the interlinking
block.

2.3.2 Mounting
Mount the bus node as follows:
1. Check the seal and the sealing surface.
2. Place the bus node in the interlinking block. Make sure that the corresponding slots with the con-
tacting terminals on the bottom of the bus node are above the contact rails.
3. Push the bus node carefully and without tilting as far as possible into the interlinking block.
4. Only tighten the screws by hand. Set the screws so that the self-cutting threads can be used.
5. Tighten the screws with a TORX screwdriver size T10 with 0.9 ... 1.1 Nm torque.
2.4 Settings of the DIL switches on the bus node
Note
This section describes how the DIL switch is set in the configuration of the bus node, as
a function module F24 (support of CC-Link version 2.0).
In order to set the bus node, you must first remove the cover for the DIL switches.
Caution
The CPX bus node for CC-Link contains electrostatically sensitive devices.
• Therefore, do not touch any components.
• Observe the handling specifications for electrostatically sensitive devices.
They will help you avoid damage to the electronics.
2.4.1 Removing and attaching the DIL switch cover
You need a TORX screwdriver size T10 to remove or attach the DIL switch cover.
Note
Observe the following instructions when removing or attaching the DIL switch cover:
• Disconnect the power supply before removing the DIL switch cover.
• Make sure that the seal is seated correctly when fitting the cover.
• Tighten the two fastening screws at first by hand and then with max. 0.4 Nm.
