A PD 600 DPI is used to provide local programmable intelligence and act as a gateway between the standard P-NET system (RS485) and the local cluster via Light-Link P-NET.
It uses either the BM 002, or the BM 010 Base Module.
The PD 600 DPI is programmed in Process-Pascal, which is an extension of standard Pascal, allowing easy declaration and utilisation of P-NET variables and objects. Programs are developed and compiled on a standard PC, then downloaded directly via a P-NET interface. Program code can be downloaded to FLASH memory.
The PD 600 has 2 standard P-NET Communication Channels.
Channel 1 is a standard P-NET RS485 communication channel for communicating with other P-NET devices outside the cluster, i.e. the rest of the system.
Channel 2 is a P-NET Light-Link communication channel intended for communicating with other locally mounted P-NET devices using the optical Light-Link interface.
