The specific I/O quantities for each model are shown in the manual table, and this is a comprehensive excerpt.

5.2 MSC-XL series I/O capability (4-6 arms)

The XL series is equipped with 2 loading arm backboards, supporting up to 6 concurrent arms, doubling I/O resources, and providing expansion space for up to 4 additional CAN IN-OUT cards. Taking MSC-XL6+4 CAN IN-OUT as an example, the system can provide:

24/12 high-frequency pulse inputs (10 kHz)

24 pulse outputs

40 solid-state relay outputs (DO-SSR)

12 way electromagnetic relay output (DO-EMR)

40 channels of digital input for communication

60 DC digital inputs

6-way RTD

14 analog inputs

6-channel analog output

7-way RS485 serial port

3 Ethernet ports

This modular expansion strategy allows users to invest accurately based on actual measurement and control points, avoiding resource waste.

Communication and system integration capability

6.1 Multi protocol Embedded Library

Fusion4 MSC-L has a rich built-in communication protocol library, which can be integrated with mainstream host systems without additional programming:

FLEXCONN (Honeywell Enraf Private Protocol)

SLIP+

Modbus RTU

Modbus TCP/IP

FMC SMITH protocol

6.2 Physical Interface

Ethernet: up to 3 10/100 Base-T ports, supporting IEEE 802.3 standard

Serial port: up to 7 isolated RS485 channels, suitable for multi-point instrument and card reader access

6.3 Level 3 System Integration

Level 1: Native integration with Honeywell Expert Terminal Manager (based on Expert PKS) to achieve integrated control from tank area metering to oil dispensing station.

Level 2: Seamless integration with third-party TAS/DCS/PLC through Modbus/LIP+, supporting standard MES/ERP data exchange.

Level 3: Remote centralized monitoring, audit tracking, batch parameter issuance, and bill of lading printing are achieved through the Fusion4 Portal software platform.

Strict environmental adaptability and safety certification

7.1 Global Explosion proof Certification

Fusion4 MSC-L has been certified for use in explosive environments as follows:

Certification System Explosion proof Mark

ATEX II 2 G Ex db [ia] IIB T6 Gb

IECEx Ex db [ia] IIB T6 Gb

FM Class 1 Div 1 Group C&D T6

CSA/CUL Class 1 Div 1 Group C&D T6

CCOE Ex db [ia] IIB T6 Gb

INMETRO Ex db [ia] IIB T6 Gb

The shell is made of anodized aluminum material with a protection level of IP66/NEMA 4X, which can resist high-pressure water gun spray and severe marine atmospheric corrosion.

7.2 Wide temperature operation

Working temperature: -40 ℃ to+65 ℃ (-40 ℉ to+185 ℉)

Storage temperature: -40 ℃ to+85 ℃ (-40 ℉ to+185 ℉)

Humidity: 5% to 95% non condensing

7.3 Electrical Isolation and Safety Design

All I/O channels adopt full isolation technology, comply with the RoHS directive, and eliminate harmful substances such as lead and mercury. The wiring terminals adopt color coding and tool free plug and unplug design to prevent installation errors and shorten on-site wiring time.

Local and remote collaborative operation and maintenance

8.1 Local Access Devices (LAD)

LAD is an inherently safe handheld terminal designed for on-site operations in hazardous areas (Zone 0/Zone 1). Implemented through LAD:

parameter adjustment

Alarm confirmation and reset

Firmware update

Configure upload/download

LAD offers three explosion-proof versions: FM, CSA, ATEX/IECEx, with part numbers 323-1392002/003/004.

8.2 Fusion4 Portal software

Portal is the unified operation and maintenance portal for the Fusion4 series, with the following core functions:

Real time monitoring: The dashboard displays the status, instantaneous flow rate, cumulative measurement, and alarm list of each loading arm.

Remote configuration: Batch modify preset quantities, PID parameters, and communication addresses.

Audit Tracking: Stores 2000 event records and supports export.

Transaction log: 10000 transaction data locally stored, supporting retrieval by time, driver, and license plate.

Bill of lading printing: compliant BOL template, supports LAN/WAN printers.

Supporting ecosystem: from additives to terminal management

9.1 Fusion4 Multiplak Pre Integrated Refueling Station

For frequently used additive injection scenarios, Honeywell offers the Fusion4 Multiplak integrated modular system. It integrates the MSC-A (additive controller) and MONOBLOCK III/II+injection head into an independent bracket, and completes hydraulic and electrical testing before leaving the factory. Users only need to connect the inlet and outlet pipelines and power supply to put it into use, greatly reducing the on-site debugging cycle.

9.2 Experion Terminal Manager（ETM）

ETM is Honeywell's advanced terminal management application for large oil depots, refineries, and chemical terminals, based on the core platform of Expert PKS, integrating:

Ship/Train/Car Dispatch

Inventory Movement Management
