SoftPLC’s DH+/RIO Smart Gateways provide protocol conversion between Allen-Bradley Data Highway Plus (DH+) and/or Remote I/O (RIO) “blue-hose” networks and Ethernet/IP, ModbusTCP, DF1, Modbus RTU, and other networks.

Smart Gateways are ideal for staged migration from devices using older, proprietary networks to new devices using Ethernet communications, combining data from multiple networks to a single Ethernet/Internet/Cellular channel for data analysis or to other high-level systems, plus many other applications.

Specifications:
  • (4) GB port Ethernet switch plus (1) GB Ethernet port, user-configurable protocols
  • (1) A-B “blue-hose” port (user configurable for DH+, A-B RIO Scanner, A-B RIO Adapter)
  • (1) RS-485 port (user configurable for Modbus or ASCII)
  • (2) USB 2.0 ports (user configurable for DF1, Modbus, ASCII)
  • (2) optional factory installed communication ports (“blue-hose” or RS-485)
  • Up to 100M words data registers

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.
