As a Remote I/O Master, users can upgrade existing A-B PLC systems without replacing or re-wiring the I/O, by exchanging the A-B PLC CPU with a Smart SoftPLC controller. Users can even re-use most of the existing logic and program documentation with SoftPLC's automated application conversion utilities. Up to 32 racks are supported.
As a Remote I/O Slave, a SoftPLC Smart Gateway can act as a bridge between an A-B PLC and many other devices on other protocols (not supported by A-B PLC's) or can add SoftPLC's Tealware I/O to an A-B PLC system. A single slave can appear as multiple racks to the A-B PLC.
