The isNet DiagM PA is a stationary PROFIBUS PA diagnostic and master module. Together with the head module isNet Lite, gateways can be built, that provide direct access from Ethernet to PROFIBUS PA devices without a DP/PA segment coupler. Thus, for example, existing plants with PROFIBUS PA can be connected directly to modern Ethernet fieldbuses such as PROFINET.
The connection to a PROFIBUS PA segment is done with pluggable screw terminals. Up to five modules can be connected to the head module isNet Lite. So, up to 5 PROFIBUS PA channels can be operated with a single head module.
The modules provide in addition to the master functionality extensive diagnostic options: List of participants of the network, error statistics, event log and telegram recording.
