For example, whether software licensing is required, the addition of relevant hardware, etc. Please discuss these in detail. Thank you!
:Lol, there are so many manufacturers like this; if I have time, I can create a table to summarize them. General communication settings are integrated into the configuration software, and authorization is mostly based on the number of your communication points ； Generally, a dedicated communication card is required, but the Siemens S7-200 CPU has a Modbus communication port built in.

For HONEYWELL, the hardware requirements are simple: a server PC with serial and Ethernet ports is sufficient, and authorization is of course required
