IE/PB Link
simplifies communication between PROFINET and PROFIBUS networks, treating PROFIBUS DP
slaves as PROFINET IO devices, facilitating parameter assignment via SIMATIC PDM. Two versions avail-
able: IE/PB LINK PN IO for standard use and IE/PB LINK HA optimized for the process industry in harsh
conditions, supporting redundant AS as PROFINET IO controller.
