GE IC695PBS301 Profibus DP slave module

IC695PBS301—01


Module Overview

The IC695PBS301 is a Profibus DP slave module in GE PACSystems RX3i series, primarily used to connect the RX3i system as a slave to a Profibus-DP network, enabling data communication with master devices (such as other PLCs or DCS systems). The module exchanges input/output data with the master via the Profibus protocol, suitable for industrial automation scenarios requiring high-speed and reliable communication.


Core FeaturesCommunication Capability
  • Slave Function: As a Profibus-DP slave, it supports periodic data exchange (input/output) and aperiodic communication (parameter configuration, diagnostics) with the master.

  • Data Capacity: Each slave supports up to 244 bytes of input data and 244 bytes of output data, meeting I/O interaction needs in most industrial fields.

  • Data Rate: Supports standard Profibus data rates from 9.6kBit/s to 12Mbit/s, flexibly adjustable based on network distance and real-time requirements.

Protocol and Function Support
  • Compatible with Profibus-DP V0 basic protocol, supporting master-slave communication mode and responding to master read/write requests.

  • Supports Synchronization and Freeze modes to ensure timing consistency for multi-slave devices (e.g., multi-axis motion control, assembly line synchronization).

  • Equipped with diagnostic functions to feedback network status and module faults (e.g., communication interruptions, parameter errors) for convenient system maintenance.

Hardware and Interfaces
  • Connector: Features a 9-pin Sub-D connector for connecting Profibus bus cables, supporting bus terminator resistor configuration.

  • Status Indication: Module status displayed via LED lights:

    • OK (Green): Power normal and module initialization completed.

    • NET (Dual-color): Steady yellow indicates Profibus communication established; red flashing indicates communication failure or slave unresponsiveness.

  • Installation Requirement: Must be installed in an RX3i universal backplane, used with an RX3i CPU, which provides power and data interfaces.

Environmental Adaptability
  • Operating temperature: 0°C ~ 60°C, suitable for conventional industrial environments.

  • Anti-interference design: Complies with industrial electromagnetic compatibility (EMC) standards, ensuring stable operation in complex electromagnetic environments.

Compatibility Requirements
  • CPU and Firmware: Requires an RX3i CPU (firmware version ≥ 2.9) to ensure protocol compatibility.

  • Programming Software: Configured via Logic Developer in Machine Edition 5.0 SP2 or higher to set slave address, data mapping, and other parameters.

  • Network Configuration: Slave parameters must be configured on the Profibus master side (e.g., Siemens PLC), assigning device addresses (1~126) and data transmission areas.

Typical Application ScenariosManufacturing Automation
  • Production Line Integration: As a slave connected to a master PLC (e.g., Siemens S7-300/400) to enable data interaction among robots, servo motors, and sensors, such as collaborative control of multi-devices in automotive welding lines.

  • Machine Tools and Packaging Equipment: Accesses the master system to synchronize parameters like spindle speed and feed rate, or control the action timing of labeling machines and palletizers.

Process Control and Energy
  • Chemical/Power Monitoring: As a slave connected to a DCS system to transmit process parameters (temperature, pressure, flow rate, etc.) or receive control commands for valves and motors.

  • Substation Automation: Connects protection devices, smart meters, etc., uploads data to the master monitoring system, and supports rapid response during faults.

Logistics and Warehousing
  • Automated Stereo Warehouses: As a slave communicating with the master PLC to control the start/stop and position feedback of stacker cranes and conveyors, enabling automated goods storage and retrieval.

  • Port Equipment: Accesses the crane master control system to transmit hook position, load weight, etc., improving loading/unloading efficiency.

Hybrid Systems and Third-party Integration
  • Multi-brand Device Interconnection: As a Profibus slave communicating with master devices from Siemens, ABB, etc., solving compatibility issues among devices from different manufacturers.

  • Distributed I/O Expansion: As a slave in large systems to expand I/O points, connecting remote sensors and actuators to reduce cable wiring costs.

Comparison with Master Module (IC695PBM300 vs IC695PBS301)
Feature IC695PBM300 (Master Module) IC695PBS301 (Slave Module)
Role Controls Profibus network, actively polls slaves Responds to master requests, passively transfers data
Number of Slaves Supported Up to 125 slaves Connects as a single slave to the network
Protocol Support Supports DP-V1 (alarm messages) Primarily supports DP-V0 basic protocol
Typical Application Builds independent Profibus networks Connects to existing Profibus networks as a slave

Installation and Configuration Key PointsHardware Installation
  • Insert into the specified slot of the RX3i backplane, connect the Profibus bus cable, and ensure terminator resistors are correctly set (enabled at both network ends).

Parameter Setting
  • Configure the slave address in the programming software (must match the address assigned by the master).

  • Map input/output data areas to define the byte range for master-slave interaction.

Network Diagnostics
  • Monitor communication quality via module LED status and programming software to troubleshoot address conflicts, cable faults, etc.


As a Profibus DP slave module, the IC695PBS301 is widely applied in industrial scenarios requiring access to standard Profibus networks due to its high compatibility and reliability, especially suitable as a data interaction hub between subsystems and master control systems.
