Product Details

IC695PBM300 Product Description

The GE IC695PBM300 PROFIBUS DP Master Module is engineered to serve as the fieldbus communication backbone within the PACSystems RX3i control platform. Rather than functioning as a standalone communication card, the IC695PBM300 operates as a tightly integrated layer within a multi-tier automation architecture — bridging the RX3i CPU logic engine to a distributed network of PROFIBUS DP slave devices including drives, valve manifolds, remote I/O stations, and intelligent field instruments.

At the control layer, the IC695PBM300 pairs directly with the GE IC695CPE305 or IC695CPE330 CPU modules, which execute the ladder logic, function block, or structured text programs that govern PROFIBUS cyclic data exchange. The CPU manages the master's I/O scan cycle, ensuring deterministic data refresh rates across all connected DP slaves. For high-availability architectures, the IC695PBM300 can be deployed alongside a GE IC695RMX128 redundancy memory exchange module, enabling hot-standby CPU configurations where PROFIBUS master state is preserved across controller switchover events.

The power layer is equally critical to stable PROFIBUS operation. The GE IC695PSA040 or IC695PSD040 power supply modules provide regulated backplane power to the IC695PBM300, ensuring that voltage transients on the AC/DC input side do not propagate into the PROFIBUS communication cycle. Clean, stable backplane power directly reduces bus error rates and slave timeout faults — a key consideration in high-cycle manufacturing environments.

On the I/O layer, the IC695PBM300 extends the RX3i's native I/O capacity by connecting remote GE VersaMax PROFIBUS Remote I/O stations (such as the IC200PBI001 PROFIBUS Interface Unit) to the central rack. This allows engineers to distribute digital and analog I/O across the machine or plant floor without running individual signal cables back to the main control cabinet — reducing wiring costs, improving signal integrity, and enabling modular machine expansion. Analog input modules such as the IC695ALG600 and digital output modules such as the IC695MDL754 can be hosted in remote VersaMax racks and polled cyclically by the IC695PBM300 master.

At the drive and actuator layer, the IC695PBM300 communicates natively with ABB ACS880 or Siemens SINAMICS G120 variable frequency drives equipped with PROFIBUS DP option boards, enabling speed reference, torque command, and status feedback to be exchanged within the same deterministic bus cycle as the process I/O. This eliminates the need for separate analog speed reference wiring and provides rich diagnostic data — including drive fault codes and operating hours — directly within the PACSystems fault table.

For HMI integration, the IC695PBM300 architecture supports GE QuickPanel+ HMI panels connected to the RX3i CPU via Ethernet, while the PROFIBUS network handles field-level device communication independently. This separation of HMI traffic from fieldbus traffic prevents operator screen refresh cycles from impacting PROFIBUS scan performance — a common source of intermittent slave communication faults in mixed-network architectures.

Contextual Integration is a defining characteristic of the IC695PBM300 deployment model. The module's GSD (General Station Description) file-based slave configuration, managed through Proficy Machine Edition, allows engineers to import device profiles for any PROFIBUS DP-certified slave — from Pepperl+Fuchs DP/PA segment couplers to Turck BL20 remote I/O gateways — and map their process data directly into the RX3i CPU's reference table. This contextual mapping ensures that every field signal has a defined, documented address within the control program, supporting both commissioning efficiency and long-term maintenance traceability.

The IC695PBM300 is deployed across a broad spectrum of industrial sectors where PROFIBUS DP remains the established fieldbus standard for deterministic, high-speed device communication.

In automotive manufacturing and general assembly lines, the IC695PBM300 manages PROFIBUS networks connecting robotic welding controllers, servo drive systems, and pneumatic valve islands — providing the cycle-accurate I/O exchange required for synchronized multi-axis motion sequences. The module's support for DP-V1 acyclic services enables online parameter reads and writes to drives and sensors without interrupting the cyclic data exchange, reducing planned downtime for parameter adjustments.

In power generation and substation automation, the IC695PBM300 integrates with PROFIBUS DP-capable protection relays, motor control centers, and intelligent electronic devices (IEDs), providing the PACSystems RX3i with real-time status and control access to switchgear and protection systems. The module's robust operating temperature range and CE/UL certifications make it suitable for installation in outdoor switchgear enclosures and harsh electrical environments.

In oil and gas processing and petrochemical plants, the IC695PBM300 connects to PROFIBUS PA field instruments — pressure transmitters, flow meters, and level sensors — via DP/PA segment couplers, enabling the PACSystems RX3i to serve as the primary process controller for continuous process loops. The module's DP-V1 Class 2 master capability supports HART-over-PROFIBUS parameter access for instrument calibration and diagnostics without requiring separate HART communicators.

In water and wastewater treatment facilities, the IC695PBM300 provides reliable communication to distributed pump drive stations, valve actuators, and flow measurement devices across geographically dispersed process areas. The module's auto-baud-rate detection simplifies network commissioning when integrating legacy PROFIBUS devices with varying baud rate configurations.

In packaging and material handling applications, the IC695PBM300 supports high-speed PROFIBUS networks operating at 12 Mbps, enabling the RX3i to coordinate conveyor drives, labeling systems, vision inspection stations, and reject mechanisms within tight cycle time budgets. The module's fault table integration with the RX3i CPU provides operators with immediate, actionable diagnostic information when a slave device goes offline — minimizing mean time to repair (MTTR) on high-throughput production lines.

Q1: How many IC695PBM300 modules can be installed in a single PACSystems RX3i rack, and what is the maximum PROFIBUS network size? The PACSystems RX3i supports multiple IC695PBM300 modules per rack, subject to backplane slot availability and CPU configuration limits. Each IC695PBM300 instance manages an independent PROFIBUS DP network of up to 125 slave devices. For large-scale architectures requiring more than 125 slaves, additional IC695PBM300 modules can be installed in the same or expansion racks, each managing a separate PROFIBUS segment. Network segmentation also improves fault isolation — a slave fault on one PROFIBUS segment does not affect communication on other segments managed by separate master modules.

Q2: Is the IC695PBM300 compatible with both DP-V0 and DP-V1 slave devices, and how is acyclic communication configured in Proficy Machine Edition? Yes, the IC695PBM300 supports PROFIBUS DP-V0 cyclic data exchange and DP-V1 acyclic services (Class 1 and Class 2 master). DP-V0 slaves are configured via GSD file import in Proficy Machine Edition, with I/O data automatically mapped to the RX3i CPU reference table. DP-V1 acyclic read/write services are accessed via dedicated function blocks in the PACSystems instruction set, allowing the CPU program to initiate parameter reads and writes to DP-V1 capable devices — such as drives and intelligent sensors — without interrupting the cyclic bus scan. This capability is essential for online commissioning, predictive maintenance data collection, and remote device parameterization in live production environments.

Q3: What warranty and supply chain support is available for the IC695PBM300, and how is the module tested before shipment? Every IC695PBM300 unit supplied by NANKMOS is covered by a 12-Month Warranty from the date of shipment.
