The gateway functionality is determined by the loadable firmware.
The firmware buffers the cyclic send and receive data of the protocol at port
X2 and the protocol of port X3 internally. The configuration tool enables the
flexible mapping of the receive data of protocol X2 to send data of the pro-
tocol X3 and vice versa.
Status information of the protocol at port X2 can be mapped into the send
data of the protocol at port X3 and vice versa.
The firmware of netTAP NT 50 as gateway does not support acyclic com-
munications or services of the supported protocols.
If the device is operated in a bus system as a master, then exactly one
slave can be connected. Thus, for example for protocols with master func-
tionality the designation „PROFIBUS-DP Master Link“ means, that one
PROFIBUS-DP Slave can be connected.

Names
The descriptive device name of netTAP devices consists of the following
parts
1. Device Type netTAP 50
2. Network on port X2 (upper port on the device), in the example DP for
PROFIBUS-DP.
3. Network on port X3 (port at the bottom of the device) , in the example
RE for Real-time Ethernet
