SIMATIC S7-1500R, CPU 1513R-1PN, central processing unit with work memory 600 KB for program and 2.5 MB for data, 1st interface: PROFINET RT with 2-port switch, SIMATIC Memory Card required
Q: Do I need two CPUs for a redundant system?A: Yes, a functional S7-1500R system requires two identical CPUs (e.g., two 6ES7513-1RM03-0AB0 units) to act as a primary and backup pair.
Q: What is the main difference between this and the standard 1513-1 PN?A: The 1RM03 supports system redundancy (R) and data synchronization, whereas the standard 1AM03 is a single-controller unit without high-availability features.
Q: Does it support Fail-safe (Safety) functions?A: No, for integrated redundancy and safety, you would need the "H" or "HF" versions (like the CPU 1518HF).
