Restrictions on the number of modules
Maximum configuration
Every ET 200X consists of a basic module and up to seven expansion modules.
Motor starter, frequency converter: A maximum of 6 motor starters or frequency
converters can be connected for each basic module (EM 300..., EM 148-FC). They
can be inserted anywhere in the ET 200X but frequency converters must always
be to the right of the motor starters.
Pneumatic interface modules: A maximum of 6 pneumatic interface modules
(EM 148-P DO 16
P/CPV...) can be connected in the ET 200X configuration.
CP 142-2 communication processor: A maximum of 6 CP 142-2 communication
processors can be connected to each basic module (except BM 147/CPU). Up to
seven CP 142-2 processors can be connected to the BM 147/CPU.
Restrictions imposed by power input
The maximum configuration is dependent on the power input of the individual
modules. The table below shows you all the possible configurations (described in
the previous sections) and specifies the restrictions imposed on them. It also
indicates ways of overcoming these restrictions.
Note
The PM 148 DO 4
DC 24V/2A power module interrupts the supply of load
voltage to the downline expansion modules of an ET 200X. It has a separate
load-voltage feed, which it uses to supply the downline expansion modules (see
Section 2.9).
