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).
