● Two R-CPUs
● Two SIMATIC memory cards
● PROFINET cable (redundancy connections, PROFINET ring)
● IO devices
● Load power supply (optional)
● System power supply (optional)
The S7-1500R redundant system should be installed either on one shared mounting rail or
on two separate mounting rails. Connecting the PROFINET cable to the PROFINET
interfaces X1 P2 R of the CPUs directly connects the two CPUs. You set up the PROFINET
ring from the first CPU to the IO devices and the second CPU with the PROFINET interfaces
X1 P1 R of the CPUs.
