1. Product Overview

• Model: MVI56‑104S

• Manufacturer: ProSoft Technology (inRAx series)

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

• Protocol: IEC 60870‑5‑104 Server (Slave) (TCP/IP Ethernet for substation SCADA)

• Function: Enables ControlLogix PLC to act as an IEC 104 server, exchanging data with IEC 104 client SCADA masters (electric utility control centers).

• Data Exchange: 4000‑word internal register space between ControlLogix tags and Ethernet; supports time‑stamped events, TRBE (Report by Exception).

2. Key Features

• Dual 10/100 Mbps Ethernet ports (P1, P2) for redundant network

• IEC 104 server compliance: Supports ASDU types, time synchronization, TRBE

• Client connections: Up to 8 concurrent IEC 104 clients

• Data capacity: 4000 words (8000 bytes) shared I/O database

• Event reporting: Unsolicited messages (spontaneous/cyclic) with millisecond time stamps

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

• Configuration: ProSoft Configuration Builder (PCB)

• 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

• Data mapping: Direct tag access + 4000‑word shared database

• Firmware: Field‑upgradeable via PCB

Ethernet Interface (P1/P2)

• Standard: IEC 60870‑5‑104 (TCP/IP), 10/100Base‑TX

• Connector: RJ45 (two ports, switchable redundancy)

• Max clients: 8 simultaneous IEC 104 client connections

• Data types: Analog, binary, counter, SOE, setpoints, parameters

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/P2 LINK: On = Ethernet link established

• P1/P2 ACT: Flashing = Ethernet data traffic

5. Installation & Configuration

1. Power off ControlLogix chassis.

2. Insert MVI56‑104S into empty 1756 slot.

3. Connect Ethernet cables to P1/P2; connect PC for configuration.

4. Power on; verify module in Studio 5000 I/O tree.

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

   • Ethernet IP addresses, subnet, gateway

   • IEC 104 server parameters (ASDU, cause of transmission)

   • Tag mapping (ControlLogix tags ↔ 4000‑word database)

6. Download configuration; test with IEC 104 client simulator/SCADA.

6. Applications

• Power substations: ControlLogix as IEC 104 server for SCADA master monitoring

• Utility SCADA: Real‑time telemetry (analog/binary), SOE, fault recording

• Renewable energy: Wind/solar farm data reporting to grid control centers

• Water/wastewater: Remote plant monitoring via IEC 104 Ethernet

• Petrochemical: Process data exchange with enterprise SCADA

7. Advantages

• IEC 104 server for Rockwell: Native Ethernet integration for ControlLogix

• Dual Ethernet redundancy: High availability for critical substation networks

• Real‑time events: TRBE + millisecond time stamps for accurate SOE

• Large data pool: 4000 words for extensive I/O and parameters

• Seamless Rockwell workflow: Studio 5000 tags, no custom logic required
