APPLICATION
A PD 602 DPI is used to provide programmable intelligence for the local cluster via Light-Link P-NET, and to provide an interface with local area networks (LAN) using the Ethernet electrical standard (10 Mb/s). The BM 016 Base module is recommended for this device.

The PD 602 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.

SPECIFICATIONS
Communication
The PD 602 DPI has 2 standard P-NET Communication Channels.
Channel 1 is a P-NET Ethernet communication channel for connecting the DPI to a LAN.
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.
