It is neither suitable nor approved for the connection of field devices from diverse manufacturers. An open, vendor-neutral fieldbus will be more effective in achieving this end.Saia®S-Net, the networking concept from Saia-Burgess Controls, is based on the RS485, Profibus and Ethernet open standards. Ethernet covers layers 1 and 2 of the ISO / OSI layer model. Based on layer 2, a variety of different protocols and applications can be run in parallel on the same network.5Layer 2 (Field Data Link-FDL) from Profibus also allows parallel running of different application protocols such as DP, FMS and others. The use of this facility allows Profi S-Net to be used to create a "Private Control Network (PCN)". This makes all Saia® units into active network components.Profibus Layer 2 (FDL) is integrated into the operating system of the PCD2.M5_ CPUs, giving these units a Profi S-Net connection with transmission speeds up to 1.5 Mbp / s.
