Expert Technical Questions

• What does 1oo2 diverse architecture mean?
• Two different systems work together for safety. Both must agree before taking action, providing fault-tolerant operation.
• How does the redundancy synchronization work?
• The SM Link connects redundant modules directly. It copies data instantly between units during hot-swap operations.
• Can I use the digital I/O for process control?
• These are dedicated safety inputs and outputs only. They manage safety functions, not regular process operations.
• What controllers work with this safety module?
• It supervises PM857, PM863 and PM867 controllers. The SM812 provides safety monitoring for these processor units.
• How does hot-swap functionality work?
• You can replace modules while system runs. The redundant partner continues operation during maintenance changes.
