GE Multilin D20/D200 Substation Controller

Electromagnetic compatibility (EMC): compliant with IEC 61326-1 Class A, CISPR 11 standards, anti-static discharge (± 8kV air discharge), fast transient (± 4kV), surge (± 2kV communication port);

Safety certification: UL/UL-C Class I Division 2 Groups A-D (temperature code T4), IEC 60255 insulation test (1500V DC), classification society certification (ABS, BV).

Software Tools and Configuration

（1） Core configuration tool

GE provides three types of software tools that cover the entire process of configuration, maintenance, and debugging:

SGConfig: a mainstream configuration tool that supports Windows 7 (32/64 bit) and XP, replacing the old version of Config Pro. Its features include:

Import/export XML format device configuration;

Visualize hardware topology and software application configuration;

Encrypt Ethernet transmission configuration files (supporting D20MX processors);

Config Pro: Old version tool (requires Windows XP), used for early D20 models, supports hardware parameter configuration and application download;

Maintenance tools:

WESMAINT: The controller has a built-in maintenance interface that allows users to view digital/analog status, error logs, and SOE data through a PC or VT100 terminal, and supports on-site debugging;

PROMAINT: A specialized maintenance tool for I/O modules that can force output signals to verify module functionality;

68K Monitor: Debugging tool that supports memory read and write, breakpoint setting, and serial loopback testing.

（2） Core software applications

The controller is equipped with multiple types of automation application modules and supports IEC 61131-3 standard PLC logic (LogicLinx module). The core applications include:

Data processing: analog averaging, data change detection, alarm priority sorting, redundant I/O switching;

Time synchronization: Supports IRIG-B code and SNTP protocol, achieving millisecond level synchronization of multiple controllers;

Communication management: Communication watchdog (monitoring link health), virtual terminal (remote access device), LAN services (TFTP, time server).

Communication Protocol and Compatibility

（1） Scope of Support Agreement

Host Protocols: Suitable for SCADA/EMS systems, including DNP3.0, IEC 60870-5-101, Modbus RTU/TCP, GE Private D.20 protocols;

IED Protocol (Slave Protocols): Covering mainstream power equipment, the core includes:

Protection device: SEL gateway SIPROTEC、Hydran；

Instruments: Power Measurement 3710, Rugby clock, Fluke temperature recorder;

Other: Modbus, IEC 60870-5-103, UCA 2.0;

Special features: Supports HART protocol compatibility (high impedance design, does not interfere with HART signals), GPS time synchronization (SOE accuracy 1ms).

Ordering and spare parts information

（1） Ordering Rules

The controller adopts the "basic model+configuration options" ordering mode, and the core parameters include:

Chassis type: Non VME single slot (D20), VME multi slot (D20/D200);

Processor board: D20ME (RS-232 only), D20ME II (RS-232/RS-485 optional);

Power module: Select according to input voltage and output voltage (e.g. D20ME-S-A-U-U: 20-60V DC input, 24V output);

Modems: Select according to communication method (dial-up/dedicated line) and speed;

I/O module: Combine discrete/analog modules as needed, paying attention to channel isolation requirements.

（2） Spare parts and replacements

Provide a complete spare parts system, including processor board, power supply, I/O module, modem. Old models (such as 580-2004 power supply) can be replaced with new models (D20ME-S-A-U-U), and the conformal coating version (suffix - CC) is suitable for high humidity and high dust environments.
