Engineering unit (See note.)
Note "EU" stands for Engineering Unit. EU is used as the minimum unit for engi-
neering 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 to +1300 ° C, 1 EU is 1 ° C, and when the
input temperature setting range is –20.0 to +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.
