5.2.5 Configuration with PROFIBUS DP connection
Configuration with IE/PB LINK HA
The IE/PB LINK HA connects PROFINET IO and PROFIBUS DP as a gateway. This enables the
IE/PB LINK HA to access all DP devices connected to the lower-level PROFIBUS network.
In the redundant S7-1500R/H system, the IE/PB LINK HA is integrated into the PROFINET
network as an S2 device.
Maximum number of DP Devices:
• S7-1500R: 63
• S7-1500H: 64
