Digital I/O module PD602B

EthernetRS-485distributed

Distributed Process Intelligence, P-NET via Light-Link and 10/100 Mbit/s Ethernet LAN 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 – 976 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. • Ethernet electrical standard (100 Mbit/s) with auto-negotiation support. • EthernetPort, IPNetTable is not supported. • Replacement for PD602, except that use with PD681 is not supported. • To retain full EMC compliance, the appropriate BM020 must be used. • Read details about this and other subjects in the tab INFO NOTES. A PD602B 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 (100 Mbit/s). The BM020 Base module is required for this device. The terminals in BM020 for P-NET RS-485 interface connections cannot be used together with PD602B DPI. The PD602B 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,
