Interface
module for
PROFIBUS DP
with bus
module and
terminating
module
The interface module interconnects
ET 200pro with the DP master and
prepares the data for the electronic
modules.
The unit is delivered with the
terminating module
②
, and the
interface module
①
is already
mounted on the bus module.
•
The bus module is the mechanical
and electrical connection element
between the various ET 200pro
modules.
•
The terminating module
terminates the ET 200pro.
The following interface modules are
available for PROFIBUS DP:
