Description
ABB TC514V2
- Technical Specifications (CI520A / CI522A — TC514V2 equivalent):
- Function: S100 bus master — generates S100 cycles, exchanges I/O image with controller
- S100 Bus: Drives up to N S100 I/O modules per cluster (typ. 32–64); multiple clusters possible via multiple CI520A or daisy-chained SPCJ4D34 clusters
- Connection to S100 Cluster: Via S100 bus cable (flat ribbon + terminator) to first termination unit or to SPCJ4D34
- Redundancy: AC 800M redundant pair each can have CI520A (both talk to same cluster — controller selects primary’s I/O image)
- Power: From CEX-bus (5 V DC)
- LEDs: Run, Err, Active, Warning
- Mounting: CEX slot AC 800M baseplate or Advant Controller comm slot
- Firmware: Loaded from controller; must match system version
- Compatibility: Works with I/O modules (SPDSI13/14, SPCIS22, SPDO…, SPAI…) & SPCJ4D34 cluster processors
- Functional Features / Application / Material / Structure / Working Principle / Installation / Precautions:
- Used when retaining existing I/O in a migration from Advant 450 → AC 800M — keeps I/O, replaces controller + INNIS21/INICT13 with AC 800M + CI520A
- Also used in pure Advant 450 systems (slot in controller — same hardware)
- Install CI520A in CEX slot → connect bus cable to first I/O rack’s SPCJ4D34 or direct to TA563 termination unit (if no SPCJ4D34 — earliest racks had bus terminator + power module only)
- In Control Builder M / Advant Eng Tool: define I/O station → assign module types (SPDSI13 etc.) → download → verify Active LED
- Precaution: bus must be terminated with 95 Ω resistor plug at last node. Total bus length ≤ limits in manual(typically ≤50 m between nodes; total ≤200 m depending on load). If mixing old & new S800 — they are NOT on same bus — S800 = HN800 (CI840A); = bus (CI520A). Keep separate.
- For redundant AC 800M: both CPUs can have — no special sync needed for I/O; controller logic uses primary’s I/O scan; standby mirrors image.
