Installing and Wiring the DP/ASi Link
4.3.2
Setting a Station Number on the DIP Switch Block
Station number
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.
DIP switch block
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.
Figure 4-3
Converting station
You have to convert the station number into binary. When doing so, bear in
numbers
mind that switch 1 corresponds to bit 0, switch 2 corresponds to bit 1, etc.
Replace cover
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.
4-12
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.
