Connection diagrams mbGate PA
The mbGate PA is available as a 2-channel model and a 4-channel model. The 2-channel model has 2
physical PROFIBUS segment connections (PA0 to PA1) while the 4-channel model has 4 physical PROFIBUS
segment connections (PA0 to PA3). By connecting two gateways over a redundancy link (RDL) you will
obtain a higher uptime (high availability).
The gateway has two 10/100 Base-T Ethernet ports (ETH1/ETH2). Both RJ45 ports correspond to IEEE
802.3 and are connected to an internal switch for line topologies. The following diagrams show the side
profile of the two mbGate PA models with the input and output interfaces and fieldbus connections at the
