Meanings of Abbreviations

The following abbreviations are used in parameter names, figures, and in text

explanations. These abbreviations mean the following:

➊ EU stands for Engineering Unit. EU is used as the minimum unit for engineering units such as °C, m, and g. The

size of EU varies according to the input type. For example, when the input temperature setting range is

–200…+1300°C, 1 EU is 1°C, and when the input temperature setting range is –20.0…+500.0°C, 1 EU is

0.1°C. In the case of analog input, the size of EU varies according to the decimal point position of the scaling

setting, and 1 EU becomes the minimum scaling unit.
