A standard NIM network interface module supports up to 32 I/O modules (excluding
PDM power distribution modules, network interface module, bus termination,
auxiliary power supplies and EOS/BOS bus extension modules).
Standard Advantys STB with 3 segments
The segments of the Advantys STB configuration shown above are composed of:
1 STB Npp 2212: NIM network interface module. It is placed at the beginning of the
primary segment. Each island must have one NIM module only.
2 STB PDT p100: PDM power distribution module (c 24 V or a 115/230 V). It is
installed immediately to the right of the NIM and provides c 24 V or a 115/230
V depending on the type of I/O modules located on the right.
3 STB AVp, STB ACp, STB DDp, STB DAp and STB DRp: I/O modules requiring
DC power or digital modules requiring AC power. They are located immediately
to the right of the PDM.
4 STB XBE 1000: EOS bus extension module. It is always installed in the farthest
right slot in the primary or extension segment, and is used to extend the island bus
to another segment.
5 STB XBE 1200: BOS bus extension module. It is installed at the beginning of each
extension segment.
6 STB XMP 1100: island bus termination (1).
7 STB XCA 100p: island bus extension cables.
Internal power supply of secondary segments: The BOS bus extension module
STB XBE 1200 supplies a c 5 V logic voltage (1.2 A) from an external c 24 V power
supply.
(1) Supplied with the corresponding NIM network interface module.
