Hello oscar; There is a bit of information on the M7-300 system available in Product Support (see the link at thhe top of this page); amongst other things, the M7-300 Hardware and Installation manual contains the following information: http://support.automation.siemens.com/WW/view/en/1177102 11.3 EXM 378-2 and EXM 378-3 Expansion Modules EXM 378-2: 6EM7 378-2AB00-0AC0 EXM 378-3: 6EM7 378-2AC00-0AC0 The EXM 378-2 and EXM 378-3 expansion modules are designed to carry interface submodules. By installing suitable interface submodules such as IF962-VGA and IF962-LPT in these expansion modules, you can connect, for example, a VGA monitor, a keyboard and a printer to your automation computer. 10.5 Address, Main Memory and Interrupt Assignments Addressing of the AT-compatible input/output components is carried out in the I/O area at addresses from 0000H to 03FFH. The addresses determined by the AT architecture are used. Unlike the original AT, the I/O addresses are fully decoded in the FM 356-4 module, so that addresses above 03FFH can be used for addressing M7-300-specific hardware.The serial interface COM1 (X1) is addressed according to the AT standard in the range 03F8H to 03FFH |
