5.4 Inputting External Temperature
By using the external temperature input, external temperature can be used for temperature-base
density correction calculation and calorie calculation. For details about the temperature-input
density correction calculation and calorie calculation, refer to Subsections 5.5.5 and 5.5.6.
This function can be used by making the minimum settings, such as scheduling and connecting
the external input to IN_1 of the MAO function block.
External input temperature is set with the following parameters.
