Universally Understood Graphical Programming
EIKON-LogicBuilder for WebCTRL is the most advanced graphical programming tool in the industry. With the click of a button, you can build complex control algorithms, diagnose problems, and run real-time or simulated operational data to evaluate the performance of a control sequence. EIKON-LogicBuilder makes it easy to understand control sequences as it does not use cryptic “line by line” computer code.
Key Features and Benefits
Intuitive graphical programming tool eliminates the need for complex programming or cryptic computer code.
Powerful library of microblocks (control functions) provide the flexibility to develop simple and complex control sequences.
Universally understood graphic symbols make control algorithms easy to understand.
Flexible simulation mode enables the user to view the control routines before system installation which simplifies development and troubleshooting.
Live Graphic Function Blocks (GFBs) are a valuable troubleshooting tool that allow system performance to be viewed in real time.
Complete integration with WebCTRL workstation software for seamless facility programming.
Instant project documentation captures development process.
An extensive library of sample GFBs provides pre-engineered solutions to many typical HVAC control applications. They can be used as-is, or easily modified in EIKON to meet special requirements.
Complete compatibility and functionality with BACnet®, ASHRAE’s industry standard protocol, for programming BACnet objects.
Automated Logic has long been known for its intuitive, powerful front-end building control software. In fact, ALC pioneered graphical programming in the industry. With our graphical user interface, users have such features as hierarchical scheduling, thermographic color floor plans, trending, alarm management, and reporting. And withWebCTRL®, our web-based building automation system, all of these features are available through a standard web browser – without any special software or plug-ins.
Time-Lapse Graphics™ is a revolutionary new feature within WebCTRL that allows operators to roll back time, up to a 24-hour slice, and play back hours of real-time data in just minutes. This innovative feature provides a quick, visual indication of any problem areas and gives facility managers a strong diagnostic tool to quickly identify and correct issues that impact energy efficiency and comfort.
Our Environmental Index™ provides a simple and effective solution. Starting with temperature as a key component of comfort, the Environmental Index (EI), expressed as a percentage, reflects how close the zone temperature is to the effective heating and cooling setpoints. Accessed through a browser using WebCTRL, the EI is shown on an easily read analog gauge, using the red segments to indicate poor environments, and graduating to green as conditions improve and the EI begins to approach 100%.

EIKON® – LogicBuilder, the most advanced graphical programming tool in the industry, replaced line-by-line programming with universally understood symbols to construct both standard and custom control algorithms. All of this combines to make the most intuitive, feature-rich, easy-to-use product on the market.
WebCTRL® Environmental Index™
Balancing Efficiency with Comfort
As energy prices continue to soar, facility managers are under increasing pressure to find ways to cut building operating costs. A simple solution would be to decrease energy consumption, but smart managers know that sacrificing comfort for energy savings could lead to even bigger financial problems. After all, studies have shown productivity decreases as comfort levels decline, leading to lost revenues in companies and difficult learning environments in school systems. What’s needed is a way to measure comfort, so managers would know exactly how far to cut energy usage without negatively impacting comfort. Automated Logic’s Environmental Index provides the solution. Since the key component of comfort is temperature, ALC’s index starts with assigning point values based on the difference between zone temperature and heating and cooling set points. Other factors, such as humidity and CO2 levels, can also be computed into the numeric system to reflect one “comfort” score for all factors. This is a powerful tool for facility managers who need to identify buildings with performance problems or ensure buildings don’t become less efficient as changes are made.
