Press Release Summary:
Comprised of Ethernet communication gateway and backplane, ETHERNET Remote I/O bridges field instruments and Modbus TCP-based Ethernet with data transfer rates to 100 Mbps. Field signals can have intrinsically safe connection for Div 1/Zone 0 applications, and up to 80 analog or 184 discrete signals can be controlled through one gateway. While high transfer frequencies require LWL connections for extended distances, copper lines are suitable for shorter distances up to 100 m.

New ETHERNET Remote I/O Communication Gateway Enables Faster Data Transfer Using Modbus TCP
System builds bridge between traditional field instruments and Ethernet, enabling users to benefit from fast data transfer rates
TWINSBURG, OH - Pepperl+Fuchs introduces ETHERNET Remote I/O - a new Ethernet communication gateway and backplane for the company's established LB/FB remote I/O system. The gateway and backplane enable the remote I/O system to speak a new communication protocol, building a virtual bridge between traditional field instruments and Modbus TCP-based Ethernet with data transfer rates up to 100 Mb/s.
"Industrial Ethernet is a hot topic, and for good reason, as users can meet Division 2/Zone 2 or Zone 1 requirements with it. And integration into existing systems is easy because the ETHERNET Remote I/O is based on the standard Modbus TCP protocol," says Brian Traczyk, Product Manager.
The illustration shows the structure of a plant in a hazardous area that can be operated locally or from a central control point. The field signals can have an intrinsically safe connection for Div 1/Zone 0 applications. Up to 80 analog or 184 discrete signals can be controlled through a single gateway. The high transfer frequencies require LWL connections for long distances, while the copper lines are suitable for shorter distances up to 100 m.
"ETHERNET Remote I/O uses existing, proven, in-use I/O modules, which now link all the functions required for process instrumentation to the Industrial Ethernet. They allow the combination of analog and digital signals in the same slave," explains Traczyk.
The modules support:
As with all Pepperl+Fuchs remote I/O systems, maintenance is possible without a hot work permit because replacing modules does not affect bus traffic.
