4.3.3 Assigning PROFIsafe Address (F_destination_address)
Introduction
In order to use
●
SM 326; DI 24 x DC 24V (as of order no. 6ES7326-1BK01-0AB0),
● SM 326; DO 8 x DC 24V/2A PM,
● SM 326; F-DO 10 x DC 24V/2A PP and the
● SM 336; F-AI 6 x 0/4 ... 20 mA HART
in safety mode, you must perform the following steps:
1.
setting the operating mode "Safety mode" for the SM 326; DI 24 x DC 24V
2. Set the PROFIsafe address = F_destination_address using the address switch before you
install the fail-safe signal module.
By contrast to the PROFIsafe address setting, which is based on the start address, there is
no correlation between the module start address and the PROFIsafe address for the
modules mentioned earlier. You set the module start address in the object properties of the
module similar to the addressing of S7-300 standard I/O modules in
STEP 7HW Config.
Setting safety mode
Set "Safety mode" in the object properties of the module in SM 326; DI 24 x DC 24V (as of
order no. 6ES7326-1BK01-0AB0) in
HW Config.
The SM 326; DO 8 x DC 24V/2A PM, SM 326; F-DO 10 x DC 24V/2A PP and SM 336; F-AI
6 x 0/4 ... 20 mA HART operate in safety mode only. This module is set up permanently for
operation in "safety mode".
Assigning PROFIsafe addresses
The PROFIsafe addresses (F_source_address, F_destination_address) are assigned
automatically to the two F-SMs mentioned earlier when you configure these modules in
STEP 7. The F_destination_addresses of the FMs are shown in their object properties in HW
Config and are returned in binary format at the "DIP switch setting" parameters.
You can edit the configured F_destination_address in
HW Config. It is advisable, however, to
use the F_destination_address which is assigned automatically.
Address switch
The 10-bit DIP switch for addressing is installed in the rear panel of the fail-safe signal
modules. This switch is used to determine:
●
whether to operate the module in safety mode or in standard mode
● In safety mode: the PROFIsafe address = F_destination_address.
The SM 326; DI 24 x DC 24V is set by default for operation in "standard mode" (all switches
are in up position, but you can set all switches to down position, see figure below).
The SM 336; F-AI 6 x 0/4 ... 20 mA HART, SM 326; F-DO 10 x DC 24V/2A PP and SM 326;
DO 8 x DC 24V/2A PM will be supplied with a PROFIsafe address of 1 to 1022, which
means "safety mode". You can change this, as shown in the figure below.
