Distributed Process Intelligence type, PD 601, P-NET via Light Link, RS-232 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 – 480 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). A PD 601 DPI is used to provide local programmable intelligence for the local cluster connected via Light-Link P-NET, and to provide an interface with MODEMs, PCs or other serial equipment, such as printers, bar code readers etc. It uses the BM 003 or BM 011 base module. The PD 601 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. VIGO Licence When the FLASH operating system is running in the PD 601, it can give licence to run VIGO version 5.3 or higher on a PC connected directly to the PD 601 via the RS232 interface. Communication The PD 601 has 2 standard P-NET Communication Channels. In the PD 601 DPI, Channel 1 is a P-NET RS232 communication channel, primarily for communicating with MODEMs or PCs, but also with other serial devices such as bar code readers and printers.
