1. Product Overview

• Model: MVI56‑103M

• Manufacturer: ProSoft Technology (Rockwell Automation partner)

• Platform: Allen‑Bradley ControlLogix (1756 chassis, single‑slot)

• Protocol: IEC 60870‑5‑103 Master (power system protection/control standard)

• Function: Enables ControlLogix PLCs to act as an IEC 103 master, communicating with protection relays, substation IEDs, and field devices in electrical substations.

• Data Exchange: High‑speed backplane data transfer between module and ControlLogix tags; supports telemetry, SOE, fault records, and time synchronization.

2. Key Features

• Dual independent master ports (P1, P2), plus CFG debug/config port

• Port hardware: RS‑232/422/485 (software selectable), electrical isolation

• Max devices: Up to 32 IEC 103 slaves total across two ports

• Protocol services:

  • Master polling: Cyclic data acquisition (YX, YC, YM)

  • Event handling: SOE (Sequence of Events), time‑stamped reports

  • Controls: Remote commands, parameter setting

  • File transfer: Fault records, disturbance data

• RTC & CMOS backup: 21‑day battery backup (non‑replaceable)

• Diagnostic LEDs: PWR, RUN, BP LINK, P1 ACT, P2 ACT

• Approvals: CE, UL/cUL, CSA, ATEX, RoHS

3. Technical Specifications

General

• Slot usage: 1 slot (1756 local/remote rack)

• Backplane current: 800 mA @ 5 VDC; 3 mA @ 24 VDC

• Data mapping: Direct tag‑based access (no M0/M1 files)

• Configuration: ProSoft Configuration Builder (PCB)

Serial Communication (P1/P2)

• Standards: IEC 60870‑5‑103, RS‑232/422/485

• Baud rate: 110–115.2 kbps

• Data bits: 8; Parity: Even/Odd/None; Stop bits: 1/2

• Connector: RJ45 (P1, P2, CFG)

Environmental

• Operating temp: 0°C to +60°C (32°F to 140°F)

• Storage temp: ‑40°C to +85°C

• Humidity: 5%–95% non‑condensing

• Vibration: 5 g (10–150 Hz)

• Shock: 30 g (operational)

4. LED Indicators

• PWR: On = backplane power OK

• RUN: On = module operational; flashing = firmware activity

• BP LINK: On = backplane communication active

• P1 ACT / P2 ACT: Flashing = data traffic on port 1/2

5. Installation & Configuration

1. Power off ControlLogix chassis.

2. Insert MVI56‑103M into empty 1756 slot.

3. Connect IEC 103 devices to P1/P2; connect PC to CFG port.

4. Power on; verify module in Studio 5000.

5. Use ProSoft Configuration Builder (PCB) to define:

   • Port parameters (baud, parity, protocol)

   • Slave addresses (1–32)

   • Data mapping (IEC 103 objects ↔ ControlLogix tags)

6. Download configuration and test communication.

6. Applications

• Power substations: Connect ControlLogix to IEC 103 protection relays, breakers, IEDs

• SCADA integration: Telemetry (YX/YC/YM), SOE, fault data collection

• Legacy system modernization: Migrate old IEC 103 networks to ControlLogix

• Distributed power: Wind/solar farm device monitoring

• Industrial automation: Process control with IEC 103‑compliant devices

7. Advantages

• Dual‑port master: Two independent networks, flexible topology

• Power protocol expertise: Full IEC 103 compliance for protection/control

• Time‑critical data: High‑precision time stamping for SOE/events

• Robust isolation: Protects against ground loops and EMI in substations

• Seamless Rockwell integration: Native tag access, no intermediate logic
