10-pos. DIP switch:
Address
The operating mode and the island number are set via the 10-pos. DIP switch.
Use switch 9 of the DIP switch to set the operating mode:
– 0 (off): VersaSafe 16 or 24 words or
– 1 (on): VersaSafe multiplexer.
In VersaSafe multiplexer mode, the data width is 8 words.
Set switch 8 and switches 2 to 0 of the DIP switch to 0 (off).
Use switches 7 to 3 to set the island number.
An "island" always comprises the IC220SDL953 and the satellites assigned to it.
The DIP switch is set to 3FF
hex
by default. This address is not valid for a VersaSafe
system; therefore, a valid address must be set.
Overview of the switch
positions
NOTE: Malfunction in the event of incorrect addressing
Make sure that in an overall system comprising the VersaSafe system and any
higher-level PROFIsafe system, the addresses (address within the VersaSafe sys-
tem and F-Address of the PROFIsafe system) are unique. Duplicate address as-
signment is not permitted.
