Information for project planning with PCD3 module holders
The internal load current taken by the I/O modules from the +5V and +V (24V) supply must not exceed the maximum supply current
specified for the CPUs, RIOs or PCD3.C200 module holders.
Example calculation for the current consumption of the internal +5V and +V (24V) bus of the I/O modules
The calculation example given shows that internal capacity is maintained in the CPU basic
module PCD3.M5540 and the holder module PCD3.C200. The CPU basic module has suf-
ficient reserves to accommodate an additional communication module in the empty 0 slot.
The holder module PCD3.C200 also has sufficient reserves for an additional PCD3.C100 or
PCD3.C110 holder module to be connected. The power consumption of the internal +5V
and +V (24 V) bus for the I/O modules is calculated in the PG5 Device Configurator.
In keeping with lean automation, it is recommended to leave the
first slot in the CPU basic module free for any subsequent expan-
sions. Both simple I/O modules and communication modules can
be used in this slot.
The total length of the I/O bus is limited by technical factors; the
shorter, the better.
The PCD3.C200 is used to extend the I/O bus or for the internal
power supply (+5V and +V (24V)) to a module segment. Please
note the following rules:
Do not use more than six PCD3.C200s in one configuration, or the
time delay will exceed the I/O access time.
The following aspects should be considered when planning PCD3 applications:

Use a maximum of five PCD3.K106/116 cables.
After each cable (at the start of a row), insert a PCD3.C200. Excep-
tion: In a small configuration with no more than 3 PCD3.C1xxs,
these can be supplied from the PCD3.Mxxx. A PCD3.C200 is not
needed
Where an application is mounted in a single row (max. 15 module
holders), after every five PCD3.C100s a PCD3.C200 must be
inserted to amplify the bus signal (unless the configuration ends
with the fifth PCD3.C100).
If the application is mounted in multiple rows, the restricted
length of cable means that only three module holders (1×
PCD3.C200 and 2× PCD3.C100) may be mounted in one row
