Main Functions

1. LAN communication protocol processing LCP processor handles DLAN and ARCNET protocol packets. Bidirectional high‑speed data interaction with SDCC drive‑controller: transmit drive set‑point commands, upload real‑time operating parameters, fault alarm and diagnostic information to HMI, local panel and plant DCS. Support jumper‑selectable isolated / non‑isolated RS‑422 DLAN communication, adapt to different field noise environment. AEE revision optimizes ARCNET physical layer circuit for better anti‑interference performance.
2. Local keypad‑display interface management Connects local alphanumeric keypad‑display panel, realize on‑site man‑machine operation: parameter browsing, fault diagnosis, local modification of drive parameters, status text display.
3. High‑speed data interaction with SDCC controller Through dual‑port shared RAM, realize real‑time data exchange with host SDCC board. Separate closed‑loop drive calculation task and network communication task, reduce SDCC processor load.
4. Communication fault diagnosis & status indication On‑board LED array indicates processor running state, network link status and data transmission activity. Detect link failure and report network‑fault status word to SDCC. Hardware jumpers configure network termination resistor and DLAN isolation mode.

Installation & Wiring Requirements

1. Cut off rack control power before installation or replacement. Non‑hot‑swappable. ESD wrist‑strap protection is mandatory during board handling.
2. Transfer U6, U7 EPROM firmware chips from original SLCC board onto DS200SLCCG1AEE board. Reproduce jumper‑configuration exactly consistent with original‑board hardware settings. Fix SLCC board onto SDCC bracket with standoffs, fasten KPPL ribbon‑cable connector firmly.
3. All network‑signal wiring must strictly follow Mark‑V / EX2000 system‑wiring drawings. Reliable protective‑earth connection for control cabinet is mandatory.
4. After replacement: Restore rack control‑power. Observe SLCC multi‑channel status‑LEDs. Verify keypad‑display normal display, DLAN / ARCNET link status. Confirm normal data interaction between SDCC, local panel and upper‑level DCS/HMI. Complete communication‑loop verification test before putting drive‑system into service.
5. Replacement note: Mismatched EPROM firmware, wrong jumper‑configuration or poor KPPL connector contact will cause communication failure, loss of local panel function, cannot upload drive‑operating‑data, may result in drive abnormal trip events. Firmware consistency check and full‑communication‑function verification test is mandatory before commissioning.
