Hot Standby System for SoftPLC ver 4.x

Now any version 4.6 or later SoftPLC with ModbusTCP I/O (including Tealware) can be used in systems requiring bumpless transfer hot backup controllers.  The solution includes a HOTBACK.TLM (firmware Cat No SPZ-HS) and a passive hardware component, called an Arbitrator (Cat No SPZ-HSA) which manages the Master/Backup status designations and I/O communication.

The Arbitrator includes redundant power input, and can provide redundant power output as well.  Click here for more information.
