Profinet / EtherNet/IP Deterministic Networks and I/O Density Scaling
The module incorporates an embedded Ethernet switch layer to maintain synchronous data throughput over Profinet / EtherNet/IP deterministic networks without external hardware components. It utilizes high-efficiency backplane bus logic to process periodic data exchange and diagnostic tracking while executing local control loops. This onboard dual-port structure allows seamless daisy chaining of network infrastructure, ensuring consistent memory synchronization and accurate troubleshooting routines during extreme I/O density scaling.
Frequently Asked Questions
Q: How many IP addresses can be bound to the dual RJ45 ports on this module?
A: The embedded Ethernet switch layer acts on a single hardware controller interface, allowing the configuration of exactly 1 IP address for both physical RJ45 ports. This enables local daisy chaining of network segments without requiring separate IP subnets.
Q: Can the RS-232 DCE serial port operate concurrently with the integrated Ethernet interface?
A: Yes. The serial port operates on dedicated UART circuitry supporting asynchronous communication from 1200 up to 115200 bps, running independently of the 200 MHz Ethernet processor communication channels.
Field Installation Guidelines
- Disconnect all primary power feeding the Series 90-30 baseplate prior to inserting or extracting the CPU module to prevent permanent electrical damage to the logic pins.
- Align the module housing into the dedicated CPU slot (Slot 1) of the baseplate, ensuring the underlying gold-finger connectors mesh cleanly with the backplane reception tracks.
- Ensure the chassis latch is pushed down completely to secure the unit against environmental vibrations.
- When utilizing the integrated ports for daisy chaining, choose category 5e or better shielded industrial Ethernet cables, grounding the overall shield wire at the entry point of the metal panel cabinet to maintain isolation integrity.
