Description
‑ Power Supply: Powered by rack back‑plane bus
‑ Power Consumption: approx 5.2 W
‑ Mechanical Structure: Eurocard plug‑in board, metal front panel, back‑plane bus connector, 9‑pin D‑SUB female PROFIBUS‑DP connector
‑ On‑board Resources: PROFIBUS protocol processing circuit, opto‑coupler isolation unit, local bus interface, module self‑diagnosis unit, onboard firmware storage
‑ Communication Interface: Internal dedicated local back‑plane bus for rack main processor; external PROFIBUS‑DP slave interface
‑ Galvanic Isolation: Opto‑isolation for PROFIBUS‑DP port
‑ Communication Rate: Auto‑baud, maximum 12 Mbit/s, comply with IEC 61158 / EN 50170 standard
‑ Station Address: configurable from 1‑125, hardware or software setting
‑ Status LED Indicators: Power indicator, Module Fault indicator, bus communication status LED
‑ Weight: approx 0.90 kg
‑ Acts as communication gateway between rack local bus and PROFIBUS‑DP field‑bus network, works as PROFIBUS‑DP slave station, interacts with upper‑level master station.
‑ Supports DP‑V0 cyclic high‑speed data exchange, real‑time upload process status, protection trip signals, feedback signals; receives down‑link control commands from master station.
‑ Supports DP‑V1 acyclic service, implements remote parameter reading‑writing and diagnostic access for rack internal modules.
‑ Module self‑diagnosis monitors back‑plane bus, power‑supply and PROFIBUS‑DP bus running status, detects bus short‑circuit, communication interruption and hardware abnormality, uploads fault alarm information to main processor.
‑ Cannot run independently; must be installed inside Procontrol P13 / REB500 rack and cooperate with CPU processing module. 1MRB178009R0001 is hardware revision variant of 500PB101 series; pin‑compatible within 500PB101 revision family, cannot directly interchange with other series communication boards。
‑ Continuously monitors module power‑supply, back‑plane bus connection and PROFIBUS‑DP bus communication health. Detected faults activate fault LED and send fault word to main processor.
‑ No local numerical display; communication status and fault codes are read via commissioning software or upper‑level HMI workstation.
‑ Module hardware failure will lead to PROFIBUS‑DP communication interruption; internal rack control‑logic operation remains unaffected.
‑ Back‑plane connector: connects to rack internal local bus for data exchange with main processor.
‑ 9‑pin D‑SUB female connector: PROFIBUS‑DP external field‑bus wiring interface.
‑ Mounting: Plug‑in installation inside system rack
‑ Operating Temperature: ‑20 °C ~ +60 °C
‑ Storage Temperature: −40 °C ~ +70 °C
‑ Relative Humidity: 5‑95 %RH, non‑condensing
‑ Protection Class: IP20 (cabinet internal)
- 500PB101 PROFIBUS‑DP communication module (1MRB178009R0001)
Complementary parts: Procontrol P13 / REB500 rack and back‑plane, main processor module, rack power‑supply unit, PROFIBUS‑DP shielded field‑bus cables, Procontrol P13 commissioning software.
‑ Power off the whole rack before inserting or removing this communication module. PROFIBUS‑DP wiring uses shielded twisted‑pair cable, single‑end shield grounding, strictly follow bus terminal resistor configuration requirements.
‑ For spare‑part replacement: Verify complete part number 1MRB178009R0001. After replacement, confirm back‑plane bus identification, download matching firmware, set PROFIBUS station address, verify cyclic data exchange and fault‑reporting function. Firmware mismatch will result in communication failure.
‑ Module hardware fault will cause loss of PROFIBUS‑DP external communication channel.
Generator‑transformer control and protection cabinets of thermal / hydro power plants; ABB Procontrol P13 / REB500 automation‑protection system; industrial spare‑part replacement for PROFIBUS‑DP slave communication gateway unit。
