The Allen-Bradley 2711-K6C5 communication module is an industrial communication interface module launched by Rockwell Automation (Allen-Bradley). It is mainly used to establish communication links between personal computers, workstations or terminals and the programmable logic controllers (PLCs) of AB. Here is a detailed analysis of this module:
I. Core Functions
Communication Capability: Enables personal computers, workstations, or terminals to communicate with AB processors and controllers through direct connection or the DataHighway Plus network.
Enhanced Response Time: By eliminating the RS-232 bottleneck, it increases the response time of applications and enhances the real-time performance of the system.
Compatibility: Provides single-cable connection with PLC-2, PLC-3, and PLC-5 series programmable controllers, simplifying wiring.
Address Selection: Supports multiple address options and can be used together with other panels installed on personal computers.
Technical Specifications
Physical Specifications:
Half-size 8-bit ISA card, can be inserted into any 8-bit or 16-bit ISA expansion slot.
Dimensions approximately 132mm × 100mm, weight approximately 0.32kg.
Electrical Parameters:
Power Requirements: 0.4A at 5V DC voltage, 0.04A at ±12V DC voltage.
Power Consumption: 2W and 0.48W respectively.
Environmental Requirements:
Recommended relative humidity range is 5% to 95% (non-condensing).
Operating temperature range is 0°C to 55°C (32°F to 130°F).
Storage temperature range is -40°C to 85°C (-40°F to 185°F).
Advantage Analysis
Compatibility: Supports the older AB PLC-2/PLC-3 series, safeguarding legacy equipment investment.
Cost-effectiveness: Compared to replacing the PLC, 1784-KT offers an economical upgrade path.
Usability: Standard ISA card design, compatible with most industrial computers.
Application scenario
Industrial Monitoring: Transmit PLC data to HMI or SCADA system to achieve real-time monitoring.
Equipment Debugging: Connect PLC directly via computer for program download and parameter adjustment.
Data Collection: Integrate into the testing platform to record PLC operation data for analysis.
