Frequently Asked Questions (FAQ)

• Q: Is the CI854A still available or is it obsolete?
  A: ABB lists the CI854A as 'Classic' status. The CI854B is the newer replacement, but we supply the Classic version for existing systems. All units are brand new.
• Q: Can I combine CI854A with CPU redundancy?
  A: Yes – master redundancy works together with CPU redundancy and BC810 CEX bus redundancy for full fault-tolerant control.
• Q: What is the difference between CI854A and CI854B?
  A: The CI854B is the newer PROFIBUS-DP master that replaces the CI854A in new installations. However, the CI854A remains fully supported for legacy systems.
• Q: Do you have this item in stock?
  A: Yes, we keep stock available for the ABB CI854A (3BSE030220R1) and ship within 5 days.
• Q: Does this module support PROFIBUS PA devices?
  A: Yes – connect PROFIBUS PA via the LD 800P linking device to the CI854A.
• Q: What is the maximum transmission speed?
  A: The CI854A supports speeds up to 12,000 kbit/s (12 Mbit/s).
