PD 600x DPI with RS485 Interface

Features

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.

Communication interfaces

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.

See General Distributed Process Intelligence information for a general description of the DPI family.

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 DPI series devices have the channels shown in the following table.

Channel No.	Channel name	Channel description
0	Service	Service channel
1	RS485Port	Comm. channel, RS485, P-NET mode or Data mode
2	LightPort	Comm. channel, Light-Link, P-NET mode or Data mode
3	LicenceCh	Channel for holding application licences (available in DPIs with operating system version 1.15 or higher)
5	OpSysCh	Program channel for operating system
6	PPProgCh	Program channel for Process-Pascal

See Overview, variables outside channels.

Memory

The PD 600 DPI is available with 4 different memory versions: Small, Medium, Medium+ and Large. The amount and type of memory for each version is shown in the table.

Type	*RAM ^)**	Program FLASH	Data FLASH
PD 600 S	64 Kbytes	64 Kbytes	128 Kbytes
