Unlocking the Secrets of PLC String Variables

Diving into T_MaxString and its Significance

In the realm of industrial automation, PLC (Programmable Logic Controller) strings play a pivotal role in data handling and exchange. Among the various types, T_MaxString stands out as an alias for STRING255, with a captivating story to unveil.

The Default Size Advantage

By default, T_MaxString is recommended for string variables. This stems from its optimal size of 255 characters, offering ample space for data storage and communication.

End of File Detection

T_MaxString is not merely a storage medium; it also possesses the ability to detect the end of a file. This crucial functionality ensures seamless data transfer and prevents errors during file operations.

Auxiliary Function for Variable Analysis

Beyond its primary role, T_MaxString hosts an auxiliary function that provides detailed information about the variable itself. With this function, developers can gain valuable insights into the structure and utilization of their string variables, empowering them to optimize PLC performance.
