Analog I/O module PD600B

RS-485distributedstandard

Distributed Process Intelligence type, P-NET via Light Link and RS-485 Interface. • Real time clock with battery backup. • 64 – 1024 kBytes in circuit programmable FLASH memory for user program. • 128 – 2048 kBytes in circuit programmable FLASH memory for user data. • 64 – 992 kBytes RAM memory with battery backup for user data (2 kBytes of RAM reserved for system variables). • Built-in replaceable lithium battery. • LED state indicators. • Low power consumption. • Process-Pascal programmable. • Automatic checksum control of program memory after each Reset. • EMC approved (89/336/EEC). New features and limitations: • PP program execution is approx. 3 times faster than the previous version. • Replacement for PD600, except that use with PD681 is not supported. • Read details about this and other subjects in the tab INFO NOTES. A PD600B DPI is used to provide local programmable intelligence and act as a gateway between the standard P-NET system (RS-485) and the local cluster via Light-Link P-NET. It uses either the BM002, or the BM010 Base Module. The PD600B 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. Communication The PD600B 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.
