The S7-1500R redundant system consists of the following components:
● Two CPUs of the type CPU 1515R-2 PN
● Two SIMATIC memory cards
● PROFINET cable (redundancy connections, PROFINET ring)
● IO devices
● Load power supply (optional)
● System power supply (optional)
You mount the CPUs on a common mounting rail or spatially separated on two separate
mounting rails. You connect the two CPUs and the IO devices in a PROFINET ring via the
PROFINET cable.
