4.3 PROFIBUS Gateway
The PROFIBUS Gateway is the interface between the process level and the master
bus system. The control signals at the process level are transmitted by the
electronic modules. These modules are connected with the PROFIBUS Gateway
via the backplane bus (EPM−T9XX). PROFIBUS Gateway and the connected
electronic modules communicate via the backplane bus. A configuration is not
required.
l PROFIBUS−DP slave for up to 32 electronic modules
l Supports PROFIBUS−DP−V1
l Integrated power supply unit for the internal voltage supply and the voltage
supply of the connected electronic modules
– Power supply unit is fed via an external DC voltage source
l Internal diagnostic protocol with time stamp
l Connection to the PROFIBUS via 9−pin Sub−D socket
l LED for status display
