Specifications and Parameters
Electrical and Environmental Parameters
- Backplane Current Load: 800mA @ 5Vdc, 3mA @ 24Vdc.
- Operating Temperature: 0°C to 60°C (32°F to 140°F); Storage Temperature: -40°C to 85°C (-40°F to 185°F).
- Shock and Vibration Resistance: 30g operational shock, 50g non-operational shock; 5g vibration resistance at 10Hz to 150Hz.
- Humidity: 5% to 95% non-condensing.
Communication and Interface Parameters
- PROFIBUS Interface: Optically isolated RS-485, supporting up to 12Mbps baud rate, compatible with PROFIBUS DPV1 protocol, and supporting 125 slaves (with repeaters).
- Diagnostic Port: RJ45 interface (connected via DB9 adapter), supporting RS-232 communication and CIPconnect Ethernet routing.
- Backplane Communication: 32-bit/33MHz VMEbus, enabling flexible configuration of input/output data blocks.
Physical Characteristics
- Dimensions: Single-slot design, compatible with 1756 backplane.
Functional Features
Protocol and Communication Capabilities
- Supports PROFIBUS DPV1 protocol, including cyclic data transmission (1536 bytes input/output) and acyclic communication (Class 1/Class 2 Acyclic services).
- Enables sync/freeze commands, slave diagnostics, address setting, and alarm handling (DPV1).
Flexible Configuration Modes
- LEGACY Mode: Fixed I/O block sizes (250 words input, 248 words output), transferring status and mailbox data via regular I/O blocks.
- FLEX Mode: Variable I/O block sizes (12–250 words input, 5–248 words output), using MSG instructions for status and mailbox data transfer to optimize remote rack performance.
Software and Tool Support
- Comes with ProSoft Configuration Builder (PCB) software, supporting GSD file import, slave configuration, checksum calculation, and project backup.
- Compatible with FDT/DTM frameworks (e.g., PACTware), allowing network configuration and monitoring via comDTM.
Installation and Configuration Process
Hardware Installation
- Insert into a ControlLogix rack slot, powered via the backplane, and connect PROFIBUS cables (shielded twisted pair with matched terminator resistors).
Software Configuration
- Install PCB software and import GSD files to configure slave parameters (address, input/output sizes).
- Load sample ladder logic (.ACD or .L5X files) in RSLogix 5000, selecting LEGACY or FLEX mode based on firmware version.
- Set backplane I/O block sizes, Requested Packet Interval (RPI), and communication path (local/remote rack).
Diagnostics and Troubleshooting
LED Status Indicators
- OK LED: Green for normal operation, red for errors or configuration anomalies.
- PROFIBUS Status LEDs: COM STAT blinking green indicates partial slave communication, solid green for full slave communication, and red for bus errors.
Troubleshooting Tools
- View slave configuration lists (SLAVE CFG LIST), data transfer status (TRANSFER LIST), and diagnostic lists (SLAVE DIAG LIST) via PCB software's diagnostic window.
- Use MSG instructions to read mailbox responses or slave diagnostic data for fault 定位 (e.g., address conflicts, configuration mismatches).
Application Scenarios
- Manufacturing Industry: Connects PLC with distributed I/O, frequency converters, etc., enabling real-time data collection and control of production lines.
- Energy Sector: Monitors sensor data from wind turbines, generators, etc., supporting predictive maintenance.
- Automation System Integration: Acts as a master station to connect PROFIBUS slave networks, suitable for remote I/O expansion or multi-device collaborative control.
Compliance and Certifications
- Meets Class I, Division 2 explosion-proof standards, applicable to hazardous areas (Groups A, B, C, D).
- Supports ATEX certification, requiring installation in an IP54-rated enclosure with a certified backplane.
Notes
- The module's non-replaceable battery backs up the real-time clock, requiring 20 hours of charging for the first power-up and lasting approximately 21 days.
- For remote rack deployment, route via EtherNet/IP or ControlNet to ensure correct communication path configuration.
- FLEX mode is supported with firmware version 1.21 and above, requiring AOI functionality in RSLogix 5000 version 16 and above.
