<#tag_name [optional input selection parameters] [optional output modification parameters]>
In the following the input and output parameters are described.
# An input parameter is used where the same tag name can represent a value for a number of different past time instants e.g. temperature for several days or several hours ago. Each of those past time instants is represented by a different value for the input parameter. So a combination of a tag name and input modification parameter lets CumulusMX select the value you want to see. Whether a particular tag name can use input modification parameters will be shown in the Full list of Webtags.
# An output parameter is used when a particular tag name can be fed through a process that alters how the output is shown:
#* Tag names representing integer values cannot have their output format modified
