1.4 Safety address
The safety address serves to clearly assign the safety modules of the SM301 type in systems
with several drives. The address "0" is not permissible.
Address switch
The safety address can be set in the left part of the housing by means of the DIP switch
0.
For setting the switch, use an appropriately small tool, e. g. a probe. The switch can only be
set if the module is not connected to a standard device. Via the switch, addresses in the
range of 0 ... 1023 can be set. Alterations by the switch with regard to the address are only
activated when the 24−V supply is switched on. The address setting "0" requires the setting
by the address code.

Address code
The safety address can also be set with the "Safety address" parameter (C15111) of the
safety module. For this, the address setting via the DIP switch
0 must be set with the "0"
setting. Via parameter, addresses can be set in a range of 0 ... 65534.
Effective safety address
The effective safety address is the result from the address switch or address parameter.
The effective safety address must comply with the module ID assigned in the safe
parameter set.
The effective safety address must also be used as target address by a master control with
safety bus (e.g. PROFIsafe/PROFIsafe target address).
Module ID
(As of SM301 V1.2)
Before the safe parameter set is downloaded, the system checks if the
module ID defined in the parameter set corresponds to the module ID saved in the safety
module. If the values are not the same, a corresponding message is displayed. This shall
ensure that the safety address is not changed by mistake during parameter setting. If the
user confirms the new value after checking it, the changed module ID will be saved
non−volatile in the SM301. Code C15017 contains the module ID saved during the last
parameter set transfer in the SM301.

Note!
A general reset does not change the stored module ID.
