4.3.2 Setting a Station Number on the DIP Switch Block
If you wish to use the station number of the DIP switch block, you must set
the configured station number of the DP/ASi link on the DIP switch block
before initial startup.
You will find the DIP switch block under the screw-type cover on top of the
DP/ASi link (refer to Fig. 4-3). Open the screw-type cover using a suitable
coin.

Using switch 8, you set whether the sta-
tion number in the EEPROM or that on
the DIP switch block is used.
With switches 1 through 7, you set the
station number.

You have to convert the station number into binary. When doing so, bear in
mind that switch 1 corresponds to bit 0, switch 2 corresponds to bit 1, etc.
Carefully close the DP/ASi link after setting the station number (torque
100 Ncm).
!
Caution
If you operate the DP/ASi link without the screw type cover for the DIP
switch block, moisture and dirt may penetrate into the DP/ASi link, possibly
resulting in destruction of the DP/ASi link.
IP 66/IP 67 degree of protection is not met when the screw-type cover is
open.
