The EtherNet/IP Linking Devices have a unique integration to Studio 5000® Logix designer, allowing for quick and easy connectivity to PROFIBUS, Modbus-TCP and serial/DF1 slave devices.
Everything is accessible from within Studio 5000, even the proprietary Master configuration software. No extra 3rd-party software or licenses needed. Just connect, configure and you're done!
In-chassis PLC communication modules defeat this advantage by creating more physical connections out of the PLC which means more potential points of failure. In addition, they require dedicated slots in the PLC rack adding cost to the overall project.
In-chassis PLC serial communications modules with their need to embed communication code into the PLC program along with the control code, add significant overhead to the total program. This can serve as a significant detriment to the performance of the total process.
Since the Linking Devices are stand-alone (distributed), they do not affect PLC backplane performance (PLC execution time), even when large amounts of data is transferred. This is especially relevant for the PROFIBUS and Modbus-TCP versions which allow for “big data” (up to 4 kB of I/O in each direction).
