Description
STBN21 network interface modules
The front panel of STBN21 network interface modules comprises:
1 A connector for connecting the island to the bus or eldbus. See the various types
of connector on the photos on pages 16 to 19.
2 STBNIP2311 Ethernet Modbus TCP/IP dual port NIM module:
A second Ethernet network connector which allows daisy-chain or daisy-chain
loop topologies.
STBNIB2212 I
nterBus NIM module:
A eldbus output connector.
3 All NIM modules except InterBus NIM:
Two rotary selector switches for addressing the nodes on the bus or the
network
4 A 24 V  external power supply connector with removable screw-type terminals
(STBXTS1120) or spring-type terminals (STBXTS2120). External Phaseo power
supplies (see page 104)
5 An LED display block indicating the different states of the island's bus: power
supply, communication, sending/receiving data, errors, etc.
Standard NIM modules Indication
Green RUN LED Island status: auto-conguration, operational, error, etc. (1)
Green PWR LED Power supply: NIM powered up, internal 5 V operational
Red ERR LED Module error (2).
1 to 3 status LEDs Indication depending on bus/network
Yellow Test LED Test mode (3)
6 A colour-coded module identication stripe: yellow
7 A screw for unlocking the module from the DIN rail
The NIM module can be removed from the island even if the product is
assembled. Simply remove the PDM (power distribution module) and then turn
this screw a quarter turn.
8 A slot for inserting an STBXMP4440 removable SIM format memory card (only on
STBN21 standard NIM modules).
9 A ap for accessing the Reset button (4) and the port for connecting a PC or an
HMI terminal (to read/write data). The PC connection is used for conguring and
setting the parameters of the island. It can also be used to update the rmware of
the network interface module (5).
The network interface modules are supplied with:
 A power supply connector of each type: screw-type or spring-type terminals
 STBXMP1100 bus terminator
 An English-language mini-CD-ROM supporting the documentation, a label sheet
template and one exchange le per network type
The network interface modules are mounted directly on the DIN rail.
The STBSUS8800 user documentation CD-ROM (to be ordered separately, see
page 22) contains specic documentation for each of the 13 NIM network interface
modules in 5 languages. These documents can also be downloaded from www.
