In the english version of the FBox library for the Energy meters ALE3 with Serial-S-Bus interface the symbol names have been mixed up so that the same value appears as "T1part" and as "T2 part" (partial counter of tariff 1 and 2 are identical, equal to the one from Part2).
If a modem is installed on port 3 and the default standby mode "S-BUS PGU" is choosen in modem driver f-box the error: "Stanby mode OFF must be used with reduced handshake (port 3)." "Fatal Error 20: f.fbd: Line 63: Caused by Modem Driver." appears.
Also the Saia PCD® COSinus based PCD systems (PCD2.M480, PCD2.M5xx0, PCD3.Mxxx0) do feature 16383 registers, not all these registers can be accessed from systems which do only feature 4095 registers over S-Bus.
There are firmware depending differences in the handling of the Serial-S-Bus communication diagnosic flags TDIA and RDIA. Those flags are refreshed continuously by older FW versions but not by the Saia PCD® COSinus Classic PCD firmware (used for PCD2.M480 and PCD3 controllers).
As a PCD system does feature various "Internet communication features" (Web Server, Ether-S-Bus, SMTP etc.), it suggests itself to connect it to the Internet using e.g. an (A)DSL router. This FAQ is aimed to explain some key-points to be considered for accessing a PCD over the Internet.
In firmware version 0A1 a new functionality has been introduced that allows to use the port 0 (D sub 9 poles) a PCS1 as free port (eg. Serial-S-Bus, MC etc.). This allows the user configuring the PCS1 e.g. as gateway, using port 0 as gateway slave port.
Due to a problem of Windows XP and Windows Server 2003, the SCOMMDRV.EXE can exhaust all available memory when using "socket communication" (Ether-S-Bus). The memory leak is related to the "Windows XP Themes" and Microsoft provides a patch for this problem.
In case a current transformator and a transfomer ration other than 1 (5:5) is used for measuring the energy with an AWD3 (with Serial-S-Bus interface) the FBox from the library 2.6.156 or older do not correctly display the current.
