Product Overview

The PROSOFT 1454-9F is a high-performance,in-chassis communication module designed specifically for Allen-Bradley ControlLogix®programmable automation controller(PAC)systems.As part of ProSoft Technology’s widely deployed MVI(Multi-Vendor Interface)family,the 1454-9F enables seamless integration between Rockwell Automation platforms and third-party devices using Modbus TCP/IP,Modbus RTU,or Modbus ASCII protocols over Ethernet or serial links.

Housed in a standard 1756 I/O form factor,the PROSOFT 1454-9F installs directly into a ControlLogix chassis alongside other I/O and processor modules,communicating with the Logix backplane via a high-speed producer/consumer model.This architecture allows real-time exchange of process data between the PLC logic and external Modbus devices—such as power meters,variable frequency drives(VFDs),remote RTUs,flow computers,and legacy HMIs—without burdening the main controller CPU.The module operates autonomously,handling all protocol sequencing,error checking,retries,and data mapping independently.

Key capabilities include support for up to 100 independent Modbus commands,configurable polling rates down to 10 ms per command,and the ability to map thousands of data points into the Logix tag database.With built-in web server diagnostics,users can monitor connection status,view transaction logs,and upload/download configuration files via any standard browser—dramatically simplifying commissioning and troubleshooting.The PROSOFT 1454-9F is widely used in oil&gas,water/wastewater,power generation,and manufacturing applications where interoperability between Rockwell systems and non-Allen-Bradley equipment is essential.

⚠️Note:The 1454-9F typically refers to a Modbus TCP/IP Master/Slave variant for ControlLogix.Always verify firmware version and exact suffix(e.g.,-9F vs.-9E)for protocol and feature alignment.

Main Features and Advantages

✅True In-Chassis Integration:

Unlike external gateways,the 1454-9F resides inside the ControlLogix rack,appearing as native I/O to Studio 5000/RSLogix 5000.Data maps directly to controller-scoped tags—no additional programming or message instructions required.

✅High-Speed,Deterministic Communication:

With millisecond-level polling and parallel command execution,the module ensures timely updates from fast-changing processes like compressor control or power monitoring.

✅Dual Role Flexibility:

Acts simultaneously as a Modbus TCP Master(to read VFDs,meters)and Modbus TCP Slave(to share PLC data with SCADA or DCS)—maximizing connectivity in hybrid architectures.

✅Zero PLC Scan Impact:

All protocol handling occurs on the module’s dedicated processor.The Logix CPU only sees pre-formatted data arrays,preserving scan time for critical logic.

✅Remote Diagnostics&Maintenance:

Access real-time statistics,error counters,and configuration via built-in web interface—no need for direct PC connection or specialized software on-site.

✅Seamless Rockwell Ecosystem Compatibility:

Visible in RSLinx Classic and Studio 5000,supports Add-On Profile(AOP)for simplified setup,and integrates with FactoryTalk View and other Rockwell tools.

Application Field

The PROSOFT 1454-9F is extensively deployed in:

Oil&Gas Pipelines:Integrating Modbus-enabled flow computers,pressure transmitters,and cathodic protection systems with central ControlLogix controllers.

Water/Wastewater Plants:Communicating with chlorine analyzers,ultrasonic level sensors,and pump VFDs from brands like Schneider,Siemens,or ABB.

Power Distribution:Reading real-time energy data from Modbus-capable meters(e.g.,SEL,GE,Eaton)into a Rockwell-based SCADA front-end.

Manufacturing:Connecting legacy CNC machines,barcode scanners,or weigh scales to modern Logix-based MES systems.

Renewables:Aggregating inverter and weather station data in solar farms using Modbus TCP over long-distance Ethernet.

Its ability to eliminate protocol silos makes the 1454-9F a cornerstone of brownfield modernization and multi-vendor plant integration strategies.

Installation and Maintenance

Installation Steps:

Power down the ControlLogix chassis.

Insert the 1454-9F into an available 1756 slot.

Connect Ethernet cable to field Modbus TCP devices or network switch.

Power up and assign IP address via BOOTP/DHCP or ProSoft’s IP Assignment Tool.

Use ProSoft Configuration Builder to define Modbus commands,data maps,and polling rates.

Import produced/consumed tags into Studio 5000 for use in ladder logic.

Maintenance Tips:

Regularly back up module configuration files(.pscfg).

Monitor“Error Count”in the web UI to detect flaky field devices.

Update firmware via ProSoft’s website to access bug fixes and new features.

Ensure network switches support full-duplex 100 Mbps to avoid latency issues.
