Reference: The range of numeral memory table entry numbers that can actually be used de-
pends on the number of numeral memory table entries set for Tools – PT Config-
uration – System setting at the Support Tool.
Change the contents of the word in the host allocated for the numeral memory
table entry.
The contents of the word are reflected to the numeral memory table entry ac-
cording to the setting of the numeral memory table entry.
Note that the contents of a numeral memory table entry allocated word can only
be read out when the memory table entry is being used for an element that is
currently displayed by the PT (if the background function is set for a trend graph,
the contents of the corresponding word are always read out). The contents of an
allocated word that is not related to the display are not read out.
