MELSEC iQ-R Series
PROFINET® IO Module
PROFINET® is an industrial network developed and managed by PROFIBUS&PROFINET International (PI). PROFINET® is a well-known and widely used network originating from Europe.
Connection to a PROFINET® network
■ Controller module
The RJ71PN92 module operates as an IO controller and supports integration into control systems based on the PROFINET® network.
■ Device module
The RJ71PN93 module operates as an IO device and supports data exchange to an IO controller on the PROFINET® network. The module supports the line, star, and ring network topologies. The module can operate as an MRC (Media Redundancy Client) in the ring topology.
