SoftPLC Corporation’s Smart SoftPLC and Smart Gateway products now support up to (2) channels of Allen-Bradley Data Highway Plus (DH+) protocol. A Smart Gateway is designed to provide a smooth upgrade of HMIs and other devices that need to communicate to A-B PLCs 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 PLCs seamlessly. No changes are required to the existing cabling, A-B PLC’s, the A-B PLC programming, or other devices on the DH+. A Smart SoftPLC can also control A-B Remote I/O. Users can upgrade existing A-B PLC systems without replacing or re-wiring the I/O or changing the DH+ network wiring. A Smart SoftPLC or Smart Gateway can support any mix of DH+, RIO Master, RIO Slave on (2) channels simultaneously.
