8.3 Key words for output in html files
To display the measured values via a web browser, VEGACOM knows a set of key words.
Depending on whether the user wants to call up the measured values in the form of lists and
tables or only individual measuring results on his page or within a context, two different cat-
egories of key words are available.
Measured value key words for lists or tables
For special applications in lists or tables, the following four key words are provided:
-
?key_list_tag?
- ?key_list_output?
- ?key_list_value?
- ?key_list_dim?
?key_list_tag?
Measurement loop designation ?key_list_tag? stands for listing of short designations of all
measurement loops in VEGA systems. If ?key_m_tag? is found
within a table or a list, the table/list will be extended by the
number of lines according to the measurement loops available.
Outside a table, ?key_list_tag? just lists all tag names.
1)
?key_list_tag("xyz”)?
Measurement loop designation With ?key_list_tag("xyz”)? the output of a specific measure-
ment loop is forced, "xyz" stands for the tag name of the re-
quested measurement loops (e.g. ?m_tag[LI3210+]? =
"LI3210+")
1)
?key_list_tag("a”-"d”)?
Measurement loop designation With ?key_list_tag("abc”-"def”)? the output of a specific
measurement loop is forced, "a" and "d" stands for the first
letters of the requested measurement loops (e.g.
?m_list_tag["a"-"d"]? = "Used oil", "Bier", "Diesel 2")
1)
?key_list_output?
Index (DCS output) ?key_list_output? stands for listing of all indices of the DCS
values which are transferred to the DCS system. If ?pls_output?
is found within a table or list, the table/list will be extended by
the number of lines according to the measurement loops avail-
able.
1)
?key_list_output(n,m)? ?key_list_output(n,m)? ?key_list_output(n,m)? ?key_list_output(n,m)? ?key_list_output(n,m)?
Index (DCS output)
?key_list_output(n,m)? stands for the index (number) of the
DCS value which should be listed. Examples: ?pls_output(1,3)?
or ?pls_output(4,8)?
