Hello, one question please: In the NA30 relay manual it is written: "the IEC 60870-5-103 (Protection equipment) is available together the Modbus protocol on some version of Pro-n devices (code NAxx#xxxxC x)." According to the configuration sheet of the Thytronic NA30 model, if there is selected T for the interface [meaning Ethernet TX (RJ45) + RS485 interface] and selected C for protocol [meaning IEC60870-5-103 protocol], do we have available, also the Modbus TCP/IP protocol ? If not, please tell what shall be done in order to have both communication protocols [meaning IEC60870-5-103 protocol and also the Modbus TCP/IP protocol] ? Same questions also for NV10P relay. Thank you.

The Thytronic NA30 relay supports both IEC 60870-5-103 and Modbus RTU protocols over RS485. There is no mention of Modbus TCP/IP or IEC 60870-5-103 being supported over Ethernet (RJ45) or of selecting protocol C for enabling both on Ethernet. Therefore, it cannot be confirmed that the NA30 supports both IEC 60870-5-103 and Modbus TCP/IP over Ethernet.

There is no information provided about the Thytronic NV10P relay, so no conclusion can be made about its communication protocol support.

Answer:
The NA30 supports IEC 60870-5-103 and Modbus RTU over RS485. Support for both over Ethernet (RJ45) with protocol C is not confirmed. No information is available for the NV10P relay.
