Help ... Support

[David Istre]

I am very, very new to programming Lookout and need help in determining if
Lookout could be used as a solution in an environment where Lookout is
attached to an Allen Bradley SLC 5/03 which also has a PanelView Monitor
attached.

Based on my understandings of our PanelView Monitor, I can display
information stored at addresses from the PLC and also write to addresses
using our PanelView Monitor. so...

1.) can Lookout directly write ASCII characters to an address on an Allen
Bradley SLC 5/03? If so how or through what type(s) of Driver?... In other
words, Lookout would drive a question and answer period with the operator at
the Panelview Monitor..

As the Operator of the Panelview Monitor inputs a Part Number (which is
totally Numeric, and I w
rite this number to an address on the SLC 5/03)
.....
2.) can Lookout determine whether the Part Number or number stored at the
address on the SLC 5/03 exists in an external ODBC compliant database and
based on the part existing or not act accordingly (add it or reject it and
notify operator)?. Through what driver(s)...SQLExec? If so, how or where do
I react to the data being existent or nonexistent (found or not found).


Thank you in advance

Hi,

1.) can Lookout directly write ASCII characters to an address on an Allen>Bradley
SLC 5/03? If so how or through what type(s)

Yes, but remember that the ASCII register is only accessed through unsigned
integer word so you will have to do a lot of Text expressions to go from
ASCII in Lookout to ascii number equivalent in PLC.

2.) can Lookout determine whether the Part Number or number stored at the>address
on the SLC 5/03 exists in an external ODBC compliant database and>based on
the part

Yep, no problem, just makle sure you get the timing right and you dont try
to query while the number is settling.

This sound very similar to a job we have just completed using Barcode reader
on a PLC to scan an Access database using Lookout, so give me a shout if
I can help.

On your question 1)
Use ascii object
question 2) If you can get the part number or the number stored in AB into
excel sheet. Then you can use DDE to check the Excel cell and then do your
logic in Lookout
