I/O modules

Product Overview

The GE HE693PBM101F functions as a Profibus DP master network module for the Series 90-30 PLC platform. This module connects GE controllers to Profibus device networks, enabling communication with a wide range of field devices. We engineered the HE693PBM101F to provide reliable, high-speed data exchange between the PLC and distributed automation components.

Technical Specifications

Key Features and Benefits

• High-Speed Profibus Communication: The HE693PBM101F supports baud rates up to 12 Mbps for fast data exchange with field devices. You achieve real-time communication with drives, I/O blocks, and intelligent sensors.

• Extensive Device Connectivity: This master module connects up to 64 Profibus DP slaves on a single network. Consequently, you build distributed automation systems with numerous field devices.

• Automatic Baud Rate Detection: The module automatically detects and configures to the network baud rate. Therefore, you eliminate configuration errors and simplify network setup significantly.

• Comprehensive Diagnostics: Front-panel LEDs and diagnostic software provide detailed network status information. You quickly identify communication problems and resolve them with minimal downtime.

• RS-232 Configuration Port: A dedicated serial port allows direct connection for configuration and troubleshooting. You access module parameters without affecting the main PLC program.

Detailed Functional Description

The primary function of the GE HE693PBM101F involves managing all Profibus DP communication between the Series 90-30 CPU and field devices. Specifically, it acts as a Profibus DP master, controlling access to the network and exchanging cyclic data with connected slaves. The module handles all protocol overhead, including baud rate detection, slave parameterization, and error handling. It automatically configures slaves according to their GSD files and exchanges process data with the CPU through shared memory. Furthermore, it provides acyclic communication for diagnostics and parameter access when required.

Network Architecture and Performance

We designed the HE693PBM101F to support flexible Profibus network topologies:

The module includes built-in termination that you enable via switch when installed at a network endpoint.

Profibus Master Capabilities

The GE HE693PBM101F provides full Profibus DP master functionality:

• Master Class 1 Operation: Cyclic exchange of process data with up to 64 slaves

• Automatic Slave Configuration: Reads GSD files and configures slaves accordingly

• Sync/Freeze Mode Support: Simultaneous output updates or input latching

• Diagnostic Functions: Retrieves slave diagnostics and reports to CPU

• Fail-safe Operation: Configurable slave behavior on communication loss

Installation and Configuration

Engineers install the HE693PBM101F in any I/O slot of a Series 90-30 rack. The process involves:

1. Inserting the module into the rack and securing with locking tab

2. Connecting the Profibus network cable to the DB9 connector

3. Setting the network termination switch if required

4. Connecting a programming PC to the RS-232 configuration port

5. Configuring the network using Profibus Configuration Software (PCS)

6. Importing GSD files for each connected slave device

7. Mapping Profibus data to PLC memory addresses

The module stores configuration in non-volatile memory within the CPU.
