7.3 Access options with PNIO

Slot functions

The products in the SCALANCE X-200 family have one slot for each switch port. Functions

that cannot be assigned uniquely to a port are assigned to the Device Access Point (slot 0).

Slot 0

• Alarms

• Data records (4.5)

Device Access Point (DAP)

• Interface connection

• C-PLUG

• Signaling contact and its

setting

• Redundant power supply

Slot 1 - 8

• Alarms

• Data records 200,202

Switch port 1 - 8

• Alarm response

• Port state

Defining the desired alarm generation response

The alarm properties can be used in three different ways:

1. The user configures exactly the assignment and required properties of the ports. The

disadvantage of this solution is that it requires coordination between the installation and

configuration teams. If the project planner specifies in STEP7 that port 3 cannot be

assigned, the installation engineer must not make any connection errors.

– Effect of the button during DataEX.

The port assignment is not stored permanently. A flashing LED indicates to the user

that the button (actuation) is not activated.

– Effect of other WEB signaling mechanisms

When the device switches to data transfer mode, the Web signaling mechanisms are

adapted to the PNIO setting. The fault mask is disabled in WEB. The message

"Setting not possible because of PNIO" is displayed.

2. The project engineering settings should be adapted in line with the installation settings

(button actuation). This operating mode can be set with an additional button on the

network component. The project engineer does not stipulate the pin assignment for the

installation engineer. The alarm response is adapted automatically. When a button is

pressed after installation, the network component reads the actual states of the

connections and records them as the desired state. When the button is pressed,

monitoring of the pin assignment is enabled. The actual state when the button is actuated

is stored permanently.

– Effect of the button during DataEX

If the device is in data transfer mode AND button actuation is set in the parameters,

the desired response for alarm processing is adapted to the new configuration. The

difference is reported accordingly.

3. The project engineering settings should be adapted in line with the installation settings

(start of DataEX).
