Page 26: Ethernet/Ip Connection
The adapter is connected to the Ethernet network using the two Ethernet interfaces on the front. Mechanically, this occurs through an M12 plug connection according to IEC 61076-2-101:2012. Three basic connection scenarios are shown below: Rockwell Automation Publication 1718-IN001A-EN-E - June 2020... - Page 27 Cable shielding: Connection to the equipotential bonding of the hazardous area (system earth) PB (Protective Bonding according to IEC 61140:2016) Elementary Safety Considerations System earth: • The enclosure is connected to the equipotential bonding PB of the hazardous area (system earth). Rockwell Automation Publication 1718-IN001A-EN-E - June 2020...
- Page 28 • The shielding must be connected to the same “PA” at both ends of the wire (or PE in the safe area). • Do not exceed the maximum cable length of 100 m. Rockwell Automation Publication 1718-IN001A-EN-E - June 2020...
- Page 29 This means that the induced noise is practically canceled out, while in parallel cores the noise is active across the entire area. A shielding keeps interfering noise away from the communication path. Rockwell Automation Publication 1718-IN001A-EN-E - June 2020...
