Address Switch for Setting the PROFIsafe Address
An address switch (10-pin DIP switch) is located on the electronic module. You set the
PROFIsafe address (F_destination_address) of the F-module at this address switch.
Note
Fail-safe modules in ET 200pro can only be used in safety mode.
Setting the Address Switch
Make sure that the address switch is set properly before installing the F-module.
PROFIsafe addresses 1 through 1022 are permitted. The figure below illustrates an example
of the switch setting for an address.
Figure 3-1
Note
An address switch of the smallest possible dimensions is installed for reasons of space
saving. This makes it sensitive to pressure and objects with sharp edges. Always use a
suitable tool to operate the address switch.
Diverse tools suitable for activating the address switch are available on the market, for
example, the Grayhill DIPSTICK. A ballpoint pen may be employed if used carefully. It is
imperative to avoid any burring which would prevent the switch from reaching its home
position. Therefore, DO NOT use screwdrivers or knives to operate the address switch.
Rules for Address Assignment
Observe the following rules when assigning the address:
• Make sure that the address switch setting of the F-I/O matches the PROFIsafe
