The General Electric IC695PBM300 is a high-performance PROFIBUS Master module designed for the PACSystems RX3i control platform. This module enables the RX3i CPU to function as a master on a PROFIBUS-DP network, facilitating seamless communication with up to 125 slave devices. It is engineered to support both standard PROFIBUS data rates and DP-V1 functionality, including read, write, and alarm messaging, making it a robust solution for distributed control and I/O management.

Features

• Supports PROFIBUS-DP V1 master functionality.
• Capable of managing up to 125 DP slave devices.
• Provides 244 bytes of input data and 244 bytes of output data per slave.
• Integrated status LEDs for both module and network health monitoring.
• Supports all standard PROFIBUS data transmission rates.

Technical Specifications

Installation Guidelines

• Ensure the RX3i CPU is running firmware version 2.9 or later prior to installation.
• The module must be installed in an RX3i Universal Backplane.
• Always power down the backplane before inserting or removing the module to prevent electrical damage.
• Ensure proper grounding of the PROFIBUS network cable shield to minimize EMI interference.
• Firmware upgrades for this module are performed indirectly via the host controller CPU using the WinLoader software utility.

Applications

The IC695PBM300 is primarily utilized in industrial automation environments requiring integration between the PACSystems RX3i controller and third-party PROFIBUS-compliant field devices, such as remote I/O blocks, variable frequency drives, and intelligent sensors.

FAQs

What is the primary function of the IC695PBM300?

It acts as a PROFIBUS-DP master, allowing the RX3i system to communicate with and control up to 125 slave devices on a PROFIBUS network.

What are the power requirements for this module?

The module draws 440 mA from the 3.3 VDC power supply provided by the RX3i backplane.

Can this module be used with older Series 90-30 hardware?

While it can be integrated into systems with legacy components, users should consult the GFK-2301 manual to review specific differences in CommReq status words and data field structures.
