Well,
netPI and NIOT-E-TPI51 device both support netX51 industrial network controller featuring the 2x RJ45 LAN port interface
In general the netX51 chip can be set to
With NIOT-E-TPI51 this is different. Node-RED PROFINET and TCP/IP support are installed natively on the system and not containers. This means mode 1 and mode 2 can be used a the same time. Node-RED PROFINET gets its PROFINET IP address assigned automatically by PLC over PROFINET and the second TCP/IP address you configure youtself in the web UI under network settings for interface "cifx0".
Now back to your question. Which of these modes do you want to use? I analysed your picture well, but I was not able to understand which mode you want to use finally. I see your blue network line and remark LAN / TCP/IP, so I suppose you want to use mode 2 only, right?
1. This question depends on mode 1 or 2. With mode 1 PROFINET it is always a 1:1. With mode 2 TCP/IP it is 1 : many, since you can use multiple s7comm nodes in Node-RED at the same time each using a different IP address to address multiple PLC over TCP/IP
2. In general a NL 50-MPI Ethernet to MPI/PROFIBUS adapter can address multiple PLCs at the same time while adapter has only a single IP address. To address subordinate multiple MPI/PROFIBUS PLCs have MPI/PROFIBUS address 2, 3 ,4 ... you have to follow the "rack" and "slot" scheme that is additional parameter of s7comm node or better said NL 50-MPI addressing scheme. The NL 50-MPI addressing scheme is explained in Hilscher's knowledge base here https://kb.hilscher.com/x/qKmKAQ

In general the netX51 chip can be set to
- PROFINET device mode to exchange data over PROFINET protocol with s single PROFINET master (PLC) across an PROFINET IP address
- TCP/IP mode to work as normal LAN network interface with an IP address
