Pre-Configured Logic that Goes Beyond the Obvious
UCOS allows you to insert devices with pre-configured logic, just like many of the latest function block and ladder logic editors.
UCOS includes a whole library of high-level and low-level devices with pre-configured functionality including:
- Switches
- Transmitters
- Controllers
- Signal select devices
- Signal limit devices
- User-defined computing devices
- Analog math functions
- Logic gates
- Counters
- Timers
... and so forth.
What makes UCOS so unique is that it goes beyond the obvious.
User-defined templates allow you to completely configure custom devices, test them, and then insert consistent copies of those devices over and over again. Templates slash development time and help ensure that all critical components meet your specification — guaranteed.
Mutually Exclusive State Logic with No Programming
In addition to the pre-configured devices and devices derived from templates, UCOS includes pre-configured functionality that you would otherwise have to program manually in traditional systems.
For example, it is important that certain devices be in only one state at a time. For example, a pump can be Starting or Running, but not both simultaneously.
Implementing this control functionality in traditional systems can require many rungs of ladder logic, the latching and unlatching of bits in memory, testing and retesting, and other tedious programming techniques to ensure that the pump never achieves multiple states simultaneously.

UCOS requires no programming and no testing to enforce mutually exclusive states.
You simply place one tag for each state into the States list. The logic for enforcing mutually exclusive states among the list of tags is pre-programmed into the logic engine.
One Tag Identifies a Fault in Any Device
Here's another example: The UCOS logic engine automatically provides an ANYFAULT tag that is the logical OR of all fault tags.
Rather than polling each fault tag, your logic can simply query the state of the ANYFAULT tag to see whether or not a fault exists.
You write less code and the logic-processing engine executes fewer lines of logic.
These are only a few examples of how UCOS provides everything you expect from your control configuration environment — and a lot more.
