GE IC695PBS301 Profibus DP slave module

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.

• 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.

• 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.

• 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.

• 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.

• 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.

• 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.

• 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.

• 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.

• 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.

• 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).

• 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.

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