Importing APT Name Files
After you have created at least one Tiway object, the Tiway class adds a
menu selection to the Lookout Options menu you can use to import an APT
name file database for each Tiway object created. You can re-import name
files as your APT programs are modified, and Lookout readjusts the aliased
name names automatically, in real time.
WX1 – WX32000 numeric yes no Word Image Inputs—16-bit values
that typically range from 6400 –
32000 for 4 – 20 mA signals, and 0 –
32000 for 0 – 5V signals.
WY1 – WY32000 numeric yes yes Word Image Outputs—16-bit values
that typically range from
6400 – 32000 for 4 –20 mA signals,
and 0 – 32000 for 0 – 5V signals.
X1 – X32000 logical yes no Discrete Inputs—unassigned Xs may
be used as control registers
Y1 – Y32000 logical yes yes Discrete Outputs—same memory
space as Discrete Inputs, so X37
references the same point as Y37.
Unassigned Ys may be used as
control registers
