Communication interfaces
The PD 664 has 3 P-NET communication interfaces: A standard P-NET RS485 interface for communication with P-NET devices outside the local cluster, a P-NET Light-Link optical interface, intended for communication with P-NET devices within the local cluster, and a GPRS P-NET communication channel, which can be used to communicate with a P-NET Gateway Service via GPRS. The P-NET RS485 and the P-NET Light-Link interfaces provide the same functionality as a PD 663 Simple P-NET Interface. Its main purpose is to provide a transparent high-speed link between two or more clusters of PD 6xx devices.
PD 664 is a P-NET master on P-NET RS485 / P-NET Light-Link.
