COM-CA-DPM

Communication Module CA-Type
PROFIBUS-DP-Master
COM-Modules are a simple and economical solution for the implementation of fieldbus interfaces.
As a compact plug-in board it contains the entire PROFIBUS including the potential-free driver interface. The data exchange with the Host systems is carried out via an easy to handle interface, which has a dual-port memory that is the same on all models. Here, the process variables are carried in a process image, whilst commands are transferred over a mailbox. The module accepts the data and carries out the data exchange via the PROFIBUS network, independently without any load on the Host system.
The configuration can be carried out with the aid of our SyCon® System Configurator, e.g. via the RS232C diagnostic interface.
