Core Functions
- Deterministic network communication: Runs ARCNET and DLAN protocols, handles real‑time data exchange between drive controllers, redundant control cores and plant‑level HMI devices.
- Network gateway function: Relays operating set‑points, process values, alarm events and diagnostic information across different system buses without overloading main CPUs.
- Hardware‑configurable network setup: Jumpers define station addresses and communication parameters to match plant network topology.
- Firmware‑driven communication processing: Dual EPROM sockets store dedicated communication firmware for field‑replaceable version management.
- On‑board diagnostics: LED indicators visualize link status for commissioning and troubleshooting network‑related faults.
Installation, Replacement & Critical Warnings
- Complete system power‑down and lock‑out procedure required before servicing. Non‑hot‑swappable. ESD wrist‑strap protection is mandatory for PCB and EPROM chips.
- Record all original jumper positions and confirm AZZ01A firmware revision before removal. Mismatched firmware or wrong jumpers will lead to total network communication loss.
- Secure coaxial network cable and all ribbon‑cable connectors firmly; poor contact causes intermittent communication dropout.
- After power restoration, perform full communication verification: inspect LED status, validate ARCNET/DLAN data transmission and confirm data interaction with HMI and drive controllers.
-
Common failure mode: Coaxial‑cable surge interference may damage network transceiver circuits. Inspect network cables when random communication errors occur.
