Hello all,

We have been using multiple CP-341's and modbus licenses for connecting peripheral devices (as RTU master) and DCS systems (as RTU slave) in our projects so far. In my current project, I need 1 Master and 3 Slave connection.

My question is:
If I buy the Modbus TCP license and one CP-343 Lean, one 5-Channel Ethernet Hub, Four Ethernet-to-RS485 Converters;
Will I be able to have 3 Slave and 1 Master connections? Can this driver operate in both modes on the same CP at a time, over a hub to different IP addresses?

Also when using this driver, Is it possible to use the same ethernet CP for connection to an HMI terminal?

Another question is, once I buy this software and install the associated FB etc on my PG, can I use it on another CP-343? Do I need to buy the driver again for each project?

Any help appreciated, thanks in advance.
