About RT Size

RT Size is a SoftPLC license setting that determines communication driver maximums.  RT Size only applies if you are using:

  • ModbusTCP Master:  # of Server Connections
  • Ethernet/IP:  # of Connection Bytes
  • A-B DH+/RIO:  # of Logical Racks
  • Tealware Local I/O: # of Discrete I/O (largest of 2 values)
Which RT Size should I choose?  

Select Lite (LT) if you are not using the protocols above. Use the table below to determine the RT Size needed for your application.
