schreiben und lesen des echo registers

Funktionscode 0x13 schreibt in das echoregister. Funktionscode 0x89 liest (siehe FG380.211 S.18).

via eb-tools

   eb-write dev/wbm0 0x420800/2 0xcafe
   eb-write dev/wbm0 0x420802/2 0x1310

   eb-write dev/wbm0 0x421802/2 0x8910
   eb-read dev/wbm0 0x421a02/2   > /dev/null

via FeSupport::MilSupport::Ifb

void simple_example(FeSupport::MilSupport::MilAccess SIO_no,unsigned MIL_addr) {
   auto busAdapterFactory = boost::make_shared<FeSupport::Scu::BusAdapters::BusAdapterFactory> (SIO_no);
   boost::shared_ptr<FeSupport::MilSupport::Ifb> ifb = boost::make_shared<FeSupport::MilSupport::Ifb>(busAdapterFactory, MIL_addr);

   if (complStat & 1) { std::cout << " ok\n"; }
   else { std::cout << " err" << std::hex << complStat << std::dec << "\n"; }
}

Example output (SIO_1,milslave address 0x10):

Functioncode-RAM der IFK beschreiben

• 0x30-0x4F sind reserviert fuer schreibe Modulbus-Funktionscode und 0xB0-0xBF zum Lesen.
• Functioncode-RAM Adresse schreiben: FC 0x62 (IFB_WR_FC_RAM_ADR)
• Functioncode-RAM Daten schreiben: FC 0x63 (IFB_WR_FC_RAM_DAT)
• Funtioncode-RAM lesen ??

Zum Beispiel in mbio64-class-def.hh (ist das die richtige?)

    /*------------------------------*/
    /* Functioncode-RAM beschreiben */
    /*------------------------------*/
    void setFctCodeRam() {
   SLong i;
   TModbusAdrbus adrWord;

   _ifb.setIfbAdr(_pCrate->getIfb().getIfbAdr()+_modulAdr-1);
   /*-------------------------------*/
   /* Function-Codes für 64-Bit I/O */
   /*-------------------------------*/
   for (i = 0; i <= C_MAX_IO64_FCTCODE; i++) {
       _ifb.writeData(IFB_WR_FC_RAM_ADR, io64Fctcode[i].fctCode);
       adrWord.wo = 0;   /* preset */
       adrWord.adr.mod =_modulAdr;
       adrWord.adr.sub = io64Fctcode[i].subAdr;
       _ifb.writeData(IFB_WR_FC_RAM_DAT, adrWord.wo);
   }  /* FOR i... */
    }  /* setFctCodeRam */

Modulbus Adress:

typedef union TModbusAdrbus {
  UWord wo;
  struct {
    UWord res : 3;  /* Bit 13..15 */
    UWord mod : 5;  /* Bit  8..12 */
    UWord sub : 8;  /* Bit  0.. 7 */
  } adr;
} TModbusAdrbus;

5bit Moduladresse und 8bit Sub-adresse. Siehe auch PZU-Doku S. 45, insb: verfuegbar auf allen Modulbuskomponenten:

Sub	w/r	bit8-15	bit0-7
FE	r	Modul-ID (Karte)	Modul-ID (Steckplatz)
FC	r	Modulskalierung	Modul-Adresse
FA	r	EPLD-ID (Karte)	frei (FF)
