Is it necessary to purchase a license according to the number of connected clients?

There is no license according to the number of connected clients, and it is possible to connect from multiple clients at the same time.

However, as the number of clients connecting at the same time increases, the load increases and the communication performance is affected. Therefore, when connecting from many clients at the same time, it is recommended to distribute the server side to multiple units.

Also, please note that there may be restrictions on the number of clients that can be connected at the same time as a product specification.
