Hello
In a substation automation project, the protection relays are ABB SPAA 341 C, they use a transmission mode based in fibre-optic serial bus, with the SPA BUS protocol.
We need to communicate them with the RTU, it doesn't support this protocol, so we need information about how to get the signals from the relays in a more common protocol like Modbus RTU, or DNP 3.0.
Are there any providers that supply a gateway with this characteristics?
Is there any other way to connect the signals from the relays to the RTU?
Thanks for your help
