Allen Bradley FlexLogix 1794System Controller

FlexLogix controllers can monitor and control I/O across the 1794 backplane, as well as over I/O links. FlexLogix controllers can communicate with computers or other processors across RS-232-C (DF1/DH-485 protocol), DeviceNet, ControlNet, and EtherNet/IP networks. To provide communication for a FlexLogix controller, install the appropriate communication interface module into the controller.

Allen Bradley SoftLogix 5800 Controllers

The SoftLogix5800 controller is a “soft controller” based on the Logix platform. The SoftLogix controller takes the control functions normally found in a dedicated programmable controller, encapsulates them in software, and runs them on a commercial operating system.
The multi-tasking operating system supports 32 configurable tasks that can be prioritized. One task can be continuous. The others can be periodic or event tasks. Each task can have as many as 100 programs, each with its own local data and logic, allowing virtual machines to operate independently within the same controller.
