Open and modular system
Example of control system conguration
NIM network interface modules STBN21, located at the beginning of each
island, are gateways for exchanging data between the network or bus master PLC
and the Modicon STB automation island.
Standard NIM STBN21 modules can be used to congure and address the
installation external devices. These settings are stored in the module’s internal RAM
or Flash memory. Optionally, they can be saved to the 32 Kb removable SIM card
STBXMP4440 (except for the address of the network connection point) to duplicate
the conguration from one island to another.
The control system conguration in the above example comprises:
1 Modicon M340/Premium/Quantum automation platform.
2 24 V  external power supply.
3 HMI terminal with Magelis XBT, XBTG, XBTGT type Modbus link
(see link cables on page 101).
4 NIM network interface module.
5 PDM power distribution module.
6 I/O modules.
7 Second STB segment.
8 Another control system.
9 Parallel interface module for TeSys U and TeSys Quickt starter-controllers.
10 Congurable Preventa XPS MC safety controller connected on the power supply
to the outputs of the power distribution module STBPDT100K.
11 ATV 312 variable speed drive.
12 Festo solenoid valves.
13 Modicon FTB IP67 I/O.
14 Parker solenoid valves.
15 TeSys U starter-controller.
