Outcodes

FactoryTalk Historian DataLink function syntax includes integer outcode

arguments. The outcodes determine how appended data (page 22) are

returned and output cells are oriented.

Outcodes are automatically generated by function dialog boxes and task

panes. However, if you enter a function manually in Excel's function bar,

you may need to calculate and include appropriate outcode values yourself.

A function outcode is a decimal representation of binary bits. In

FactoryTalk Historian DataLink, bits carry the following meanings:

 1st bit: Show Timestamps bit

 2nd bit: Orientation bit (columns/row)

 3rd bit: Show Percent Good bit

 4th bit: Hide Count bit

 5th bit: Show Extended Status bit

 6th bit: Show Annotations bit

 7th bit: Show Start Time

 8th bit: Show End Time

 9th bit: Show Min/Max Time

For example, a 0 outcode in a PICurrVal() function results in a current

snapshot value in the designated output cell. An outcode of 1 places a time

stamp in column one and the snapshot value in column two of a 1 x 2

array. An outcode of 2 places a time stamp in row one and the snapshot

value in row two of a 2 x 1 array.
