The Smart SoftPLC and Smart Gateway products from SotPLC Corporation (Spicewood, TX) now support up to (2) channels of Allen-Bradley Data Highway Plus (DH+) protocol. This interface provides the lowest cost, most comprehensive connectivity to A-B DH+ on the market. A Smart Gateway can provide customers with a smooth upgrade of HMI's and other devices that need to communicate to A-B PLC's on a DH+ network, but have no DH+ interface. Smart Gateways provide numerous modern Ethernet, serial and fieldbus protocols for the HMI, driver or other device. The Smart Gateway then communicates over DH+ to the A-B PLC's seamlessly. No changes are required to the existing cabling, A-B PLC's, the A-B PLC programming, or other devices on the DH+. Features include:

  • Control of A-B Remote I/O.
  • Capability to upgrade existing A-B PLC systems without replacing or re-wiring the I/O or changing the DH+ network wiring.
  • Support of any mix of DH+, RIO Master, RIO Slave on (2) channels simultaneously.
