The 1SAP172900R0011 is a CM589-PNIO PROFINET IO RT communication module. It has a data transmission rate of 100000 kbit/s over two Industrial Ethernet interfaces. The module communicates via a serial interface internally, while the external ports handle PROFINET traffic.
Integration notes
The IP20 rating keeps it suited for clean, enclosed panel environments. Both Ethernet ports are live for daisy-chaining; the module can sit at the end of a PROFINET line or in a ring without additional switching hardware. No auxiliary power supply is required beyond the backplane bus.
