Features and Benefits

  • Supports CompactLogix processors with 1769 I/O bus capability version 16 and greater (MicroLogix 1500 not supported)
  • Add-on Instruction creates UDTs, providing logical definitions for I/O, status, and control data
  • Add-on Profile support for RSLogix 5000, improving integration in the CompactLogix system
  • Diagnostic data available in RSLogix 5000 controller tags, allowing decisions to be made based upon node health
  • Module configuration backed up in CompactLogix project (ACD file)
  • Module acts as a co-processor reducing impact to PLC scan time
  • Supports up to 10,000 words of data
  • Supports up to 250 Modbus Commands per port
  • Each port can be configured individually as a Modbus Master or Modbus Slave device
  • Supports Enron and Daniel-style Floating point data implementations
  • Suitable for SCADA and field device interface applications
