push buttons)

The optional C990-G0xx push-button extensions for the Control Panels CP2xxx and CP39xx from

Beckhoff Automation provide additional input options. Push-button extensions that match the design of

the Control Panels enable application-specific use of electromechanical buttons. Selection and key

switches can also be integrated. The push-button extension is located below the touchscreen. The

number of buttons that can be added depends on the display size.

The actuation of the emergency stop and other buttons is transferred to the controller via USB and can be

read with TwinCAT. Optionally, customers may use the signals for additional purposes. The emergency

stop has two N/C contacts and one N/O contact. The signal of the N/O contact is transferred to the

controller. The two N/C contacts can be used by the customer. One button actuates two N/O contacts,

one of which is available as a potential-free contact for use by the customer. The indicator lamps are

controlled via USB.

By default the first button is supplied with a green cap, the second with a red cap, and the other buttons

with white caps (see Fig. 1). Other button cap color options are available for retrofitting:

Fig. 9: Rear view of CP2924-0000-G007

USB input

The USB input is located on the emergency stop PCB. The push-button extension is controlled via the

USB port of the CP39xx/CP2xxx. The USB input is pre-wired in the factory.

K-bus

The conversion from USB to K-bus takes place on the emergency stop PCB. The button PCBs are

connected via the K-bus interface of the emergency stop PCB. Each button PCB has a K-bus input and a

K-bus output. The last button PCB is terminated with a jumper at the K-bus output. The K-bus wiring of

the PCBs is done in the factory.

Power supply

The button PCBs are supplied via the voltage input of the first button PCB, from where the power supply

is looped to the next button PCB with a connecting cable, and so on. The connecting cables are provided

ex factory. The wiring of the voltage input is done by the customer.

Connector strips

On the PCBs connection strips are available so that the signals can be used for additional purposes. The

wiring is done by the customer.

C9900-G0xx 15

2.4.3 Toggle switch

An application example for the connection strips is the use of a toggle switch. If a toggle switch is installed

instead of a button, which is to be queried electronically in two positions, the potential-free contact of the

button (see item 3 in Fig. 7 & Fig. 8) can be used for this purpose. The N/O contact can be read-in with

the aid of the additional digital input (see item 4 in Fig. 7 & Fig. 8).

2.5 Wiring of the connection strips

Releasing the spring contact strip

The connection strip can be wired in unconnected or connected state. To release the spring contact strip

from the pin contact strip, use a suitable tool, for example a screwdriver, to guide the locking device in the

direction of the connection strip. The spring contact strip can be removed from the handle plate while the

locking device is held in this position.

Fig. 10: Releasing the spring contact strip

Wiring

The cables are connected as follows:

1. Open a spring-loaded terminal by slightly pushing with a screwdriver or a rod into the square

opening above the connection strip.

2. The wire can now be inserted into the round terminal opening without any force.

3. The terminal closes automatically when the pressure is released, holding the wire safely and

permanently.

Not more than 24 V are allowed to be connected to the button or emergency stop PCB!

Connecting to 24 V

The power supply has to be provided by the customer. The customer has to connect 24 V to the first push

button PCB (see Fig. 11). The connected 24 V can be switched with the push buttons and are used to

supply the mounted LEDs.

Fig. 11: Connection of 24 V power supply

Product description

16 C9900-G0xx

DIP switch

The dip switch can be used to loop the 24 V supply of the PCB (see item 2 in Fig. 7 & Fig. 8) directly via

the second N/O contact of a button. In this way the cabling effort at the pin contact strip (see item 3 in Fig.

7 & Fig. 8) can be reduced.

Example:

Button 1 needs to switch 24 V. Turn the DIP switch to position 1 (see Fig. 12). If button 1 is now actuated,

24 V is applied to contact 2 on the connector strip 3.

Fig. 12: Configuration of the DIP-switch

2.6 Inserting self-printed labels

The blank label sheets for the push buttons of the push-button extension offered under order code

C9900-Z260 can be printed with a conventional office printer and then inserted in the push-button

extension.

Fig. 13: Releasing the button cap and inserting the label

First remove the button caps of the buttons that are to be labelled. Use a suitable tool, for example a

screwdriver, to lever off the button caps and remove them. Then remove the labels from the sheet and

place them in button caps. The labels have tabs to aid alignment. Then place the button cap with the label

on the button and push it in.

Fig. 14: Replacing the button caps

Special instructions for the TwinCAT System Manager

C9900-G0xx 17

3 Special instructions for the TwinCAT System

Manager

The push-button extension can be integrated via the search

function in the System Manager. The PCBs in use are shown

as terminals in the System Manager (see Fig. 10).

KL1002 stands for the emergency off PCB. Channel 1 is the

N/O contact actuated by the emergency stop. Channel 2 is

not used.

The terminals following the KL1002 represent the button

PCBs used in the configuration. The number of displayed

inputs and outputs is independent of the number of buttons

on a PCB.

For a three-button PCB the inputs “Button 1” to “Button 3”

correspond to the N/O contacts that are actuated by the

respective buttons. The inputs “Button 4” to “Button 6”

correspond to the digital inputs that are allocated for

customer use. “Button 7” and “Button 8” are not used. The

outputs “LED 1” to “LED 3” are connected to the indicator

lamps. “LED 4” to “LED 8” are not used.

For a four-button PCB the inputs “Button 1” to “Button 4”

correspond to the N/O contacts that are actuated by the

respective buttons. “Button 5” to “Button 8” correspond to the

digital inputs that are allocated for use by the customer. “LED

1” to “LED 4” are connected to the indicator lamps. “LED 5” to

“LED 8” are not used.

Since it is not directly apparent from the diagram which PCB

is at which location, section 7.3 of the annex contains an

overview of PCB combinations for different devices. Please

note that in cases where three- and four-button PCBs are

combined, the three-button PCBs are always listed first.
