Product Q&A

• Q: What is the benefit of the 25KB CPU on this module?
  • A: It manages the ARCNET stack independently, ensuring the main PLC program execution remains stable and fast.
• Q: How is the module addressed on the network?
  • A: Addressing is typically handled through the AC500 engineering software (Automation Builder) configuration.
• Q: Can this be used with S500 I/O?
  • A: Yes, it is designed to work within the AC500/S500 ecosystem via the standard communication slots.
