Communication between individual modules in this machine is based on Ethernet, which is why PROFINET is suitable for both local and global networking. The open architecture of the PROFINET Ethernet standard enables IP communication beyond the confines of local area networks. This offers you a series of benefits, including optimal machine servicing and quick troubleshooting, validation of diagnostics data in the PROFINET network with the help of the TIA Portal, and diagnostics of the entire machine over vast distances per remote maintenance access with our management platform SINEMA Remote Connect management platform.
How remote maintenance work can be handled in practice can be seen in the video.
