2.2 Safety-related method of operation of the

FL PN/PN SDIO-2TX/2TX

Depending on the selected configuration, the safe PROFINET gateway couples the safe

process data of two PROFINET/PROFIsafe systems. Safe output data in PROFINET

system 1 is supplied as safe input data in PROFINET system 2 and vice versa.

It is therefore possible to exchange safety-related data between two safety-related

controllers and to implement safety functions beyond the system limits of a safety-related

PROFINET/PROFIsafe controller.

Please note that the safe PROFINET gateway transmits the safe process data from one

PROFINET system to the other without any further measures/changes.

Safe state/behavior

in the event of an error

(failure state)

The safe state is where the value “0” (substitute value) is forwarded to the next

PROFINET/PROFIsafe network or the transmission of safe messages is set.

All serious errors in the device, which can lead to the loss of or adversely affect the safety

function, switch the device to the failure state (safe state).

This state is indicated by the red “FS” (Failure State) diagnostic indicator on the front of the

device (see item 6 in Figure 2-3 on page 28).

The failure state can only be exited by switching the supply voltage of the safe PROFINET

gateway off and on again.

For descriptions of error states, associated effects, and appropriate measures for error

removal, please refer to “Errors: Messages and removal” on page 51.

WARNING: Observe the safety integrity level of the entire safety function/chain,

otherwise there is a risk of death or injury and loss of functional safety

When specifying the safety functions, take into consideration the entire safety chain,

which extends over two PROFINET systems coupled via a safe PROFINET gateway. It is

important to note that input signals acquired with a specific safety integrity level in one

system can only ever be processed as an output signal with the same safety integrity level

in the other system. The safety integrity level in a safety function/chain must always be the

same.

WARNING:

Since it is possible for two PROFINET/PROFIsafe networks coupled via the safe

PROFINET gateway to cover the same address areas, please take measures to prevent

the RJ45 plugs on the device being mixed up. If this cannot be achieved adequately, the

F-Addresses must be uniquely assigned within the PROFINET/PROFIsafe networks

coupled by the safe PROFINET gateway.
