  1. 2604 Software version 5.xx • 2704 Software version 5.xx • Existing units are upgradeable Modbus Master Communications

  2. Uses standard Modbus modules • EIA 232 or 485 • Slot J only, 9600 baud • Max 8 individually addressed slaves • Broadcast mode • Slave Address 0 • Possible Slaves • S2000, 2500, 5100 series, 900EPC, 902 plus more • 25 Parameters in 2604 • 38 Parameters in 2704 • to be extended in future • Resolution, timeouts, retries etc are all user • configurable Modbus Master Communications

  3. Extrusion Controller • 2704 for melt pressure • 1 or 2 pressure inputs • Transducer Calibration • User interface for 2500 • 2500 for temperature loops • 8 Loops per base Master Communications - Application 1
