ABB PNI800

Product Brief (CI854A / PNI800-equivalent):

The module provides a Profibus DP-V0/V1 (master or slave) port to the ABB controller (AC 800M via CEX-bus, or Advant OCS via its bus). It handles cyclic I/O data exchange with up to 125 slaves (master mode), supports acyclic record read/write (DP-V1) for drive parameter access (PPO types 1–6 with ABB drives), and connects via 9-pin D-sub (RS-485 isolated) to the Profibus DP network. For Profibus PA, a DP/PA link (e.g., ABB PA Link) is required between CI854A and PA segment.

Description

ABB PNI800

  • Technical Specifications (typical CI854A— PNI800-equivalent):
    • Protocol: Profibus DP-V0, DP-V1 (Master or Slave configurable)
    • Port: 1 × 9-pin D-sub female (RS-485, optically isolated ≥1 kV)
    • Baud Rate: 9.6 kbps – 12 Mbps auto-detect (master) or fixed (slave)
    • Max Slaves (as Master): 125 (theoretical); practical ≤64 per scan time
    • GSD File: Provided for 3rd-party masters; for ABB drives use ABB RPBA-01.gsd / EDG file
    • Acyclic Services: DP-V1 Record Read/Write — used for ABB drive parameter access (PPO5/PPO6)
    • Indicators: Module Run, Err, Bus Active, Warning LEDs; port Activity LED
    • Power: From CEX-bus (5 V DC, typ. 150 mA) or baseplate (for Advant version)
    • Mounting: CEX slot of PM865/PM866/PM510 (AC 800M) or Advant OCS communication slot
    • Operating Temp.: 0 °C to +60 °C
    • Certifications: CE, UL, cUL, Profibus International Certified
  • Functional Features / Application / Material / Structure / Working Principle / Installation / Precautions:
    • Connect Profibus cable A/B to D-sub pin 3 (B = Data+) & pin 8 (A = Data−); pin 1+4+6 often +5 V (not used for DP); pin 5 = shield (connect to connector shell → earth)
    • In Control Builder M / Advant Eng Tool: add CI854A → assign node address (unique on Profibus net, 1–126) → import GSD of slave devices → configure I/O mapping → download
    • Terminate both ends of Profibus segment with 220 Ω resistor (built-in on some connectors; otherwise external)
    • Precaution:​ Reversing A/B wires prevents communication — double-check polarity. Always use shielded twisted-pair (Profibus cable type A per IEC 61784-5-3). Do NOT forget termination resistors at both physical ends. For DP-V1 parameter access ensure acyclic message timeout in logic is set appropriately.
