Configuration 39
3.1.2 Structure of the I/O Peripherals
The I/O peripherals consist of a number of I/O modules depending on the task. These
modules are combined in subracks and are connected to the controller via PEAB or
Modnet 1/SFB. These modules form the interface to the process, in which each of
them processes up to 32 process signals.
The I/O modules designed with front connections are summarized on page 22, those
with rear connection on page 23.
3.1.2.1 Structure of the I/O Peripheral with Front Connection
The I/O modules with front connection are connected via the Modnet 1/SFB. The bus
interface is an RS interface and is located in the controller on the front of the BIK 151
or BIK 812. An expansion is possible with any primary subrack via the Modnet 1/SFB.
Expansions via Modnet 1/SFB (distributed expansions) can be:
DTA 102 or DTA 112 secondary subrack with max. 4 I/O modules with front connec-
tion and one DEA as the Modnet 1/SFB network
or
DTA 103 or DTA 113 secondary subrack with max. 9 I/O modules with front connec-
tion and one DEA as the Modnet 1/SFB network
or
the righthand half of the DTA 101 primary subrack with max. 4 I/O modules with
front connection and one DEA as the Modnet 1/SFB network
or
DEA-H1 or DEA-K1 compact device with an integrated Modnet 1/SFB network, 24 in-
puts and 16 outputs as semiconductors (DEA-H1) or as relays (DEA-K1).
The DEA 106, DEA 116 and DEA 156 are seen as DEA modules. Table 16 shows
which DEA are suitable for which subrack.
