PD 602x DPI with Ethernet LAN Interface

Specific Features

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.

Communication interfaces

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.

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

Programming

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.

The PD 602 DPI devices have the channels shown in the following table.

Channel No.	Channel name	Channel description
0	Service	Service channel
1	EthernetPort	Comm. channel, Ethernet, P-NET 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 602 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 602 S	64 Kbytes	64 Kbytes	128 Kbytes
PD 602 M	464 Kbytes	512 Kbytes	1024 Kbytes
PD 602 M+	976 Kbytes	512 Kbytes	1024 Kbytes
PD 602 L	464 Kbytes	1024 Kbytes	2048 Kbytes
^*) 2 Kbytes of RAM reserved for system variables.
