On which systems is the Mode D (still) supported?

FAQ #101025

 

History
Early PCD systems used the P800 protocol which bases on the Mode D as PGU protocol (for configuring and programming a PCD as well as for data exchange from and to the PCDs). The Mode D telegrams are in accordance with ISO 1745, IBM BSC (first defined by IBM in 1970, in the "IBM bisync publication) and DIN 66019 and has been used on serial lines.
Over the years the mode D became obsolete and has been replaced by much more powerful communication protocols which are not only implemented for serial interfaces (on the PCD these are e.g. Serial-S-Bus, Ether-S-Bus, Profi-S-Bus, FTP, http etc.). Due to this fact, the Mode D is no longer supported by recent PCD systems.

Systems supporting the "Mode D"
The Mode D is no longer used for PGU communication, and PCD systems which have been developed after the PCD2.M110/M120 do use S-Bus as PGU protocol. In a second step, the Mode D (SD/MD mode) has been removed from the firmware. Please refer to the table below which indicates the PCD systems which do support the Mode D:
