Information on mounting the bus node on the decentralised electrical connecting plate CAPC-... can be found in the mounting instructions that accompany the connecting plate.

For mounting the bus node on a valve terminal with I-Port interface, proceed as follows:

1. Inspect the seals and sealing surfaces on the bus node and valve terminal.

2. Push the bus node onto the valve terminal in the correct position with no tilt.

3. Screw in the three self-tapping screws. When screwing the screws in again, use existing threads.

4. Tighten the screws in a diagonally opposite sequence with a tightening torque of 0.7 ± 0.1 Nm.

5 Connection and display components

The following electrical connection and display components can be found on the bus node:

1 Notes relating to this description

This description includes information for mounting the bus node on an I-port-com­ patible device from Festo (e.g. valve terminal with I-port interface) and for installa­ tion of this combination in a higher-level control system.

Information about the CP system can be found in the CP system description

(P.BE-CPSYS-...) and in the description for the electrical interface

CPX-CP-4-FB (P.BE-CPX-CP-...). These documents can also be found online.

2 Intended use

The bus node type CTEU-CP has been designed exclusively for use as a slave on the

CP bus. It may only be used in its original status without unauthorised modifica­ tions and only in perfect technical condition.

The bus node is intended for use in an industrial environment. Outside of industrial environments, e.g. in commercial and mixed-residential areas, actions to suppress interference may have to be taken.

3 Target group

The target group of this description consists of trained specialists in control and automation technology who have experience with installation of slaves on the CP bus.

Warning

Risk of injury to people, damage to the machine and system resulting from un­ controlled movements of the actuators and undefined switching states

Switch off the operation and load voltage supplies.

Switch off the compressed air supply.

Exhaust the valve terminal pneumatics.

6 Connecting the CP bus and load voltage

The bus node has a signal and load voltage supply. It also supplies voltage to the devices connected via the I-port interface.

If the continuing CP connection is not used, the cover cap must be mounted to ensure the IP65/IP67 degree of protection.

Screw the cover cap by hand until it noticeably engages against the stop.

The bus node is supplied with the cover cap already mounted.

Warning

Danger of electric shock

For the electrical power supply, use only PELV voltage sources in accordance with IEC 60204-1 (Protective Extra-Low Voltage, PELV).

Observe the requirements of IEC 60204-1 for PELV circuits.

Through the use of PELV circuits, protection against electric shock (protection against direct and indirect contact) is ensured in accordance with IEC 60204-1.

When using external connecting cables, please note:

– The maximum length of the external connecting cable to a valve terminal is 15 m.

Note

Electromagnetic interference

Establish the connection to the functional earth via the connected device or the electrical connecting plate CAPC-....

Note

Damage to the electronics

The bus node includes electrostatically sensitive devices.

Do not touch any components.

Observe the handling specifications for electrostatically sensitive devices.

Note

Use cover caps to seal unused connections. The IP65/IP67 degree of protection is thereby ensured.

Functional test:

– The LED “PS” is illuminated green when the power supply is correctly presented.

– The LEDs “X1” and “X2” illuminate green if a device is connected and the I-Port communication is ready to function (

è

Chap. 8).

Note

Malfunction due to impermissible cabling

To connect the bus node to the CP string, only use the special CP cables from

Festo ( è www.festo.com/catalogue).

7 Basic setting for fieldbus communication

7.1 Removal of the DIL switch cover

To set the DIL switches, the cover must be removed:

1. Switch supply power off.

2. Unscrew the two mounting screws of the transparent cover and remove the cover.

7.2 Setting the DIL switches

The bus node has two DIL switch groups, each with 6 DIL switches.

When delivered, all DIL switches are set to OFF ( è Fig. 2).

4 bytes for outputs (32 inputs and 32 outputs).

7.3 Mounting of the DIL switch cover

1. Place the cover carefully on the bus node. Make sure that the seal is positioned correctly!

2. Tighten the mounting screws with max. 0.4 Nm using a Torx screwdriver (size

T10) or a corresponding slotted head screwdriver.

The assignment of bus addresses to physical outputs/valves of the con­ nected devices can be found in the respective product documentation.
