Design
Figure 2-20 DP/AS-Interface Link 65
The DP/AS-interface link has a robust aluminum die-cast casing with the degree of
protection IP 65. In terms of water tightness, it complies with the standard
“Enclosures for Electrical Equipment UL 50, Type 4”, and is suitable for
temperatures from -25
°
C to +60
°
C. On the casing, there are diagnostic LEDs for
PROFIBUS-DP and the AS interface. The node address for PROFIBUS-DP can be
set using DIL switches or using an EEPROM. To set the address using the
EEPROM, you can use the ET 200 handheld. The DP/AS-interface link can be
installed anywhere and in any position. The attachment to PROFIBUS-DP is via a
12-pin round connector, the attachment to AS-interface is via a 4-pin modular
connector (M12 AS-interface attachment).
