of the PM6 SIMADYN D CPU module and has the following performance
features:
• Computational performance
• DRAM (8 MB)
• SRAM (256 KB)
• Replaceable program memories
• Two interfaces are available to load the user program into the program
• 8 interrupt tasks can be called via 8 digital inputs.
• RS-232 interface (V.24) with service protocol DUST1 (19.2 kBd) for:
• 8 LEDs to display the operating status
2-4
− 128 MHz, 64 bit RISC floating-point-processor
− fastest cycle times of 0.1 ms, typical 0.5 ms
− Program code is loaded when the memory module is loaded and
expanded when the memory module is initialized (boot flash is
provided separately)
− Data memory for the operating system, communications, message
buffer, trace
The buffered SRAM contains the following data, which should be
saved (non-volatile) even when the power fails:
− Error diagnostics of the operating system ("exception buffer")
− max. 1000 process quantities, configured using the SAV function
block
− Data, traced using the message system or trace function
(optional SRAM configuring)
− MC 521 mit 2 MB Flash EPROM und 8 kByte EEPROM
− MC 500 mit 4 MB Flash EPROM und 8 kByte EEPROM
memory:
− via a PCMCIA-IPC card slot (load offline)
− directly from the PC via the serial service interface (loading online)
−
CFC test mode (incl. download)
− "Service/IBS"/TELEMASTER [IBS = Start-up]
