Core Functions

1. DLAN & ARCNET Industrial‑LAN Communication Processing Equipped with dedicated LCP (LAN Control Processor), dual EPROM firmware sockets and dedicated communication RAM. It implements proprietary DLAN (Drive Local Area Network) token‑passing coaxial‑cable network and ARCNET protocol communication. It handles bidirectional high‑speed data exchange between Mark‑V rack internal subsystems, remote drive units, and upper‑level host workstations over RG‑62A coaxial cable links. It supports up to 255 network nodes for distributed‑system interconnection.
2. Backplane Bus Data Interaction within Control Rack Installed as plug‑in module inside Mark‑V cabinet. It communicates with other core processor boards via rack backplane connectors. It forwards turbine process data, alarm events, set‑point commands and drive‑system status across the control‑rack; acts as network gateway between internal‑rack logic and external distributed nodes.
3. Embedded Network‑protocol Firmware Execution Two field‑replaceable EPROM chips store SLCC network‑stack firmware. On‑board RAM provides data‑buffering for network‑packet forwarding. It completes protocol encapsulation‑decapsulation, packet filtering, error‑checking and retransmission logic for industrial LAN traffic without relying on external host CPU resources.
4. On‑board Hardware Diagnostics & Status Indication LED status indicators display board power‑on, network‑link activity and communication‑fault status. Built‑in hardware self‑test monitors processor operation, memory integrity and transceiver‑circuit health. Communication‑link failures, packet‑loss and hardware‑abnormal alarms are reported to Mark‑V main controller for event logging and maintenance‑alerting. Conformal‑coated PCB resists humidity and corrosive atmosphere in power‑plant cabinet environments.More products: www.plcva.com
5. Isolated Transceiver Circuit for Harsh‑site Communication Integrates isolated and non‑isolated signal‑transceiver circuits. It suppresses ground‑loop noise and electromagnetic interference on long‑distance coaxial‑cable network wiring, stabilizing data transmission for turbine‑control and large‑drive‑system distributed‑nodes.
6. Support for Turbine‑drive Distributed‑system Architecture Enables interconnection between Mark‑V turbine‑control rack and external GE EX2000 / DC2000 variable‑speed drive‑units. It transmits torque‑setpoint, speed‑command and drive‑fault feedback between turbine master‑control and power‑drive subsystems, realizing coordinated control of turbine‑driven large‑motor equipment.

GE DS215SLCCG1AZZ01A Assembled System‑LAN‑Communication Printed Circuit Board

Applications & Purposes

DS215SLCCG1AZZ01A is legacy dedicated assembled‑communication board for GE Speedtronic Mark‑V turbine‑control and matched high‑power drive‑systems. It cannot operate independently; it must work with complete Mark‑V rack hardware and corresponding firmware versions.plcva.com

Typical Application Industries ‑ Thermal power plants: gas‑turbine & steam‑turbine generator‑sets ‑ Petrochemical & refinery: turbine‑driven large‑compressor units ‑ Metallurgical rolling‑mill heavy‑duty DC‑drive control systems ‑ Oil‑gas on‑site power‑generation and compressor‑package control ‑ Existing‑plant lifecycle‑extension maintenance and spare‑part‑replacement projects

GE DS215SLCCG1AZZ01A Assembled System‑LAN‑Communication Printed Circuit Board

Main Purposes

1. Serve as core LAN communication gateway for Mark‑V system, realize DLAN / ARCNET network‑data transmission between control‑rack, remote drive‑units and host‑workstations.
2. Transmit turbine process‑data, control‑setpoints, alarm‑messages and drive‑system status over industrial coaxial‑LAN links.
3. Realize data‑interconnection between Mark‑V turbine controller and GE EX2000/DC2000 high‑power drives, supporting coordinated turbine‑drive compound‑control.
4. Detect network‑link abnormality and board‑hardware faults, output diagnostic‑alarms for on‑site troubleshooting.
5. Function as ready‑to‑install OEM‑equivalent spare‑part: replace faulty SLCC board to restore Mark‑V system LAN‑communication function for running legacy power‑plant equipment.
