Central Interface Module (Cim); Function And Design - Siemens SIPLUS HCS Series Operating Instructions Manual

System configuration
Several POMs can be operated on one CIM. This supports the implementation of centralized
heating applications, for example, in thermoforming, where the heating elements are
implemented in numerous arrays and the modular heating control system is located in a
central control cabinet.
Communication over PROFINET or PROFIBUS
PROFINET unites the industrial experience of PROFIBUS with the openness and flexible
options of Ethernet. PROFINET enables high-speed and secure data exchange at all levels,
thus making it possible to implement innovative machine and plant concepts.
PROFIBUS has been established for years as the fieldbus for machines and plants. Based
on serial bus technology, it is the foundation for the distributed concepts that are common
today.

Function and design

Function
The Central Interface Module (CIM) handles the communication with the higher-level
controller and with the connected Power Output Modules (POM). In addition, the CIM
provides the 24 V DC power supply for the connected POM and fan modules.
