ABB PROCOLOR P 88QT03 bus coupling module

ABB PROCOLOR P 88QT03 bus coupling module

Product positioning and purpose

88QT03 is the bus coupling module of ABB PROCOLOR P system, used to connect the bus of PROCOLOR P and PROCOLOR-PS protection system. The core function is to achieve data transmission and protocol conversion between the two, supporting the connection of devices such as bus isolation amplifiers and bus control modules for PROCONTOL-PS, and suitable for integration scenarios of protection equipment and control systems in power systems.

Hardware and interface characteristics

Physical specifications

Occupying 2 partitions, it can be inserted into a multi-purpose processing station of the PROCONTOL bus system.

Interfaces: 1 SS standard interface (station bus), 1 SEA standard interface (PROCONTROL-PS bus), hardware input connection port.

Power supply: Only 24V power is required, and other required voltages are generated internally.

Address and Installation

The station bus address is related to the installation location and only supports even module addresses. Adjacent odd addresses are automatically occupied and cannot be assigned to other modules.

Core functional modules

Station bus function module

Process data communication with the station bus and follow the instructions of the 88TV01 station bus control module.

The internal functions of the monitoring module are displayed with fault status through LED indicator lights (such as ST, STEA).

Shared memory is divided into receive and send buffers, caching station bus data.

processing module

The core processing unit, driven by microprocessor II, supports data grouping, limit generation, and event processing.

The functions include:

Telegram (binary/analog) between PROCONT-PS and station bus.

Generate limit signals for analog quantities (up to 4 limits/analog quantity, supporting 0.39%~6.25% hysteresis values).

Monitor the rationality of input signals and trigger fault positions (such as SMX, MXX).

Support measurement range expansion (parameters X1 and X2 must meet | X2-X1 | ≥ 6.25%).

PROCONTROL-PS bus function module

Communicate with the PROCONTROL-PS bus through the SEA interface and follow the instructions of the 70BV01 control module.

Shared memory cache PROCONT-PS bus data, supporting bidirectional transmission.

Data transmission and processing

transmission capacity

Station bus: receives 255 telegrams and sends 200 telegrams.

PROCONTROL-PS bus: A total of 256 telegrams were sent and received.

Internal transmission time: ≤ 20ms (10ms for infinite value generation).

Data processing logic

Input direction (PROCONTOP-PS → station bus): analog grouping, limit value generation, event triggering (such as limit value changes, signal fluctuations).

Output direction (station bus → PROCONT-PS): Supports multi address output and programmable measurement range expansion.

Initialization and Configuration

Initialization trigger

When powered on or receiving the "Reset processing" command, the STEA LED flashes for about 4 seconds.

User List Configuration

Load the grouping list, limit list, etc. into RAM through PDDS (Programming Diagnostic Display System), verify them, and save them to EEPROM.

Support online modification of user data and configuration of PROCONTROL-PS bus module addresses (to avoid input module address conflicts).

Diagnostic and alarm functions

LED indicator

ST: Module and data transmission failure (red constantly on).

STEA: ROCONTROL-PS bus fault (red constantly on), initialization flashing (4 seconds).

SIM: Analog output activated (yellow constantly on).

EAVE: Participate in PROCONTROL-PS bus data transmission (green constantly on).

Diagnostic register

Register 246: Record parameters, process channels, bus connections, and other faults.

Register 211: Stores external interference signals (such as SME1-3, STX) and hardware errors (EEPROM, RAM failures).

Expansion and simulation functions

Extension module support

Connect up to 4 NPB-8000-LON/LON FTT10A modules, 4 NPB-8000-232/RS-232 modules, and 2 NPB-8000-2X-485/RS-485 modules
