How can I get informations (Baud rate, Status...) from the DDC Rail and Save modules?

FAQ #100430

 

Diagnostic Registers
To access the information directly you have to configure a "master gateway port" on the PCD. Now you are able to connect the modules using the Online Debugger (Connect / S-Bus Station). With Display Register xx you are able to read the following informations:

The information can also be read an used in the programm.

Attention
Older Versions of the PCD7.Lxxx had always the staus register on regsiter 7 and 10. So if you exchange an old modul and you where observing register 10 as status register you have to change register 10 to register 7.

Status regsiter information
The most important information are stored in Bit 0 to 5 and 8 to 10 of the status register. Bit 12 to 15 are containing the status information of the swich (Automatic=0/Manual=1) when the modul is supporting it (Switch 1-4 on Bit 12-15: L100/L101/L110/L200/L201) (Switch 1-2 on Bit 12 and 13: L120/L121). All other Bits are reserved for factory tests

Bit 0	1=Device recognized last transmission 0=Device did not recognize last transmission
Bit 1	1=Last transmission was a broadcast 0=Last transmission was not a broadcast
Bit 2	1=Last transmission came from master 0=Last transmission came from a slave
Bit 3	1=CRC of last message was correct 0=CRC of last message was incorrect
Bit 5	1=Device has executed an internal reset 0=Device function is OK
Bit 8	1=Internal bus to EEPROM is OK 0=Internal bus not working perfectly
Bit 9	1=EEPROM data memory is OK 0=EEPROM data memory is faulty
Bit 10	1=Baud rate uploaded form EEPROM 0=Baud rate is at default value (9600 Bd.)
