In my previous post, I shared the importance of setting tag limits to prevent bad data from causing issues in SCADA systems. Now, let’s talk about another essential safeguard — clamping values.
Since WinCC Unified V17, users have been able to set upper and lower limits for tags to ensure the value stays within a defined range. This feature is essential for preventing invalid inputs and protects connected devices from unexpected inputs.
As a gas turbine controls engineer, part of my job involves working with ancillary systems such as the fire and gas system. In gas turbine packages, fire and gas systems are used to detect fires and flammable gases which are hazards to the operating environment.
