Modbus TCP Connection via RTE Ethernet Ports

[Armin@netPI]

Hi Chris,

we are in a quote phase with the manufacturer of the netPI to get a UL certificate cULus(UL61010-2-201). After we have the quote we will trigger UL.

Then a word to the Modbus/TCP firmware and the examples. The three examples we provide on github are the original examples customers are gettin when they are becoming a netx51 chip customer and are designing their own netX host platforme. So it was no work to put them on github in the latest revision.

Unfortunately we brought the source code for Modbus/TCP not into the same c-coded format as we did that for the three other examples. Currently it is a C++ coded version from year 2011 and would need a reengineering. Next point is even if we have a netX51 chip running on netPI this is a different type of hardware and would need the development team to rebuild a new branch for this netPI/netX51 combo.

And since other customers want to run CODESYS PLC with Raspberry PROFINET,EtherNet/IP, EtherCAT Master Stacks over netX TCP/IP Ethernet and Node-RED Modbus TCP Stacks exist already ... it was easier for us to provide a TCP/IP Ethernet over netX than to dig into details of Modbus examples.
