Functions; Profinet Io - Siemens SIMATIC ET 200MP Manual

Product overview

2.2 Functions

Maximum configuration
● 512 bytes I/O data per station
● The integrated power supply of the interface module feeds 14 W into the backplane bus.
Up to 12 I/O modules can be supplied this way. The exact number of operable modules is
determined by the power budget (see relevant section in the ET 200MP distributed I/O
system (http://support.automation.siemens.com/WW/view/en/59193214) system manual).
● A maximum of one power supply module (PS) upstream from the interface module and
two downstream from the interface module is possible.
● If you use a power supply module (PS) upstream from the interface module, the
maximum possible configuration is a total of 32 modules (up to 30 modules downstream
from the interface module).
