ABB CI506-PNIO PROFINET CANopen Gateway Module
Two serial channels, one CANopen master and local S500 expansion combine multiple field networks behind a PROFINET IO RT device.
Product Overview
ABB CI506-PNIO is an AC500 PROFINET IO RT gateway that combines two configurable serial UART interfaces with one CANopen master interface. The serial ports support RS232, RS422 or RS485 and ASCII communication, while the CANopen master operates at up to 1 Mbit/s and supports the documented network size. A local I/O bus can host up to ten AC500 I/O modules through the TU520-ETH terminal arrangement.
Performance
- Operates as a PROFINET IO RT device for cyclic controller communication.
- Provides two serial UART interfaces for RS232, RS422 or RS485 ASCII devices.
- Includes one CANopen master interface with data rates up to 1 Mbit/s.
- Supports up to 126 CANopen slave nodes under the documented addressing limits.
- Connects as many as ten local AC500 I/O modules through the S500 I/O bus.
- Uses two RJ45 ports integrated in the TU520-ETH terminal unit.
