Benefits over other Protocols

  • Modbus RTU is easier to implement than newer protocols
  • Modbus RTU is already commonly found in most automation systems
  • Modbus RTU requires much less memory for storage than BACnet or Ethernet/IP
    • Modbus RTU requires 2Kb on an 8-bit CPU whereas BACnet or Ethernet/IP may require 30 – 100Kb of memory.
