Dear Forum,

We are currently switching to a native Codesys controller, and I'm currently trying to determine the correct license.

I have a question regarding the Modbus instances.
With the Standard S license this is set to 4 (See picture).

In our projects we are using a lot of communications to Modbus servers using a Codesys Controller, for this communication I'm using the ModbusFB library (supplied by 3S) (see picture).

In my project I would like to use more than 4 instances of the ClientTCP FB.

My question is, is this now capped at 4 possible connections with the standard S license.
Or do these function blocks have a different relation with the license?

Some clarity on this topic would be very welcome.

Thank you in advance
