GE IC695PBS301 PROFIBUS Slave Module Guide: Key Specs
GE IC695PBS301 PROFIBUS Slave Module Overview
The GE IC695PBS301 is a PROFIBUS slave module from the RX3i PacSystems series. It provides reliable slave communication over a PROFIBUS DP network. Engineers use this module to connect I/O devices to a PROFIBUS master, such as a PLC or DCS. The module supports universal backplanes and fits into a single slot. This design ensures straightforward integration into existing RX3i chassis.
Key Technical Specifications
The IC695PBS301 operates at 3.3 V DC and consumes 440 mA. It uses a 9-pin D-sub connector for PROFIBUS DP communication. The module supports all standard PROFIBUS data rates and handles up to 244 bytes of input and 244 bytes of output data. It also supports DP-V1 read-write and alarm messages. The operating temperature range is 0 to 60 °C, with storage from -40 to 85 °C. These specs make the module suitable for demanding industrial environments.
LED Indicators for Diagnostics
Three LEDs provide clear status information. The green PROFIBUS OK LED indicates power application and backplane reset completion. The bicolor NETWORK LED shows PROFIBUS telegram transmission in green and turns red for critical communication issues. The bicolor MOD STATUS LED displays the module's operating condition. These indicators help technicians quickly diagnose network and module health.
Communication Behavior and Firmware Updates
As a PROFIBUS slave, the IC695PBS301 does not initiate bus access; it responds to master requests. It automatically exchanges data with the master device. The module acknowledges received messages and transmits data only when the master requests it. This ensures efficient and deterministic communication. Firmware updates occur indirectly through the host controller CPU using the WinLoader software utility. WinLoader provides updates to the PROFIBUS module software, keeping the module current with protocol enhancements.
The module's universal backplane support and single-slot form factor save space in the RX3i system. Engineers benefit from robust PROFIBUS DP slave functionality for reliable field device integration. The automatic data exchange reduces programming overhead, making the IC695PBS301 a practical choice for distributed I/O applications in process and factory automation.
