Rakesh,

We do exactly as you and Alex describe - use one generic overlay for multiple 
devices.  We set the P1,P2,P3,etc variables as required in a DM Command Pick 
Action and then open the overlay with the ov command.  One word of caution - if 
you open multiple overlays using the same Px variables the values will be 
changed with each new overlay opened.  That is, if you set P1 = C1:B1.P1 for 
Overlay 1 and then set P1 = C2:B2:P2 when opening Overlay 2 the value will be 
changed for Overlay 1.  This can be a definite problem if you use the values 
for any control action.  We work around this by including a close -all command 
prior to the ov command so only one overlay will be open at a time.  Perhaps 
Alex or some of the other gurus could comment or have additional suggestions on 
this practice.

Below is an example of the DM Command script for the overlay pick on the main 
graphic.

= P1 EVP01:YY20_CBOL
= P2 EVP01:YY20
= P3 EVP01:SC20_FAULT
= P4 EVP01:SC20
close -all
ov \usr\plenco\overlays\GDEV_VFDovl -l UR 

Note:  Reference the contents of the variable in a dynamic or action in the 
overlay use $Px.
To reference the text of the variable in a text contents dynamic just us Px (no 
$).

Re: one indication object which has to change color on two conditions ( i.e 
Global variable x=1 or y=1 )

FoxView can't do logic or arithmetic on connected variables. To get it to work 
with one variable, you need to put both conditions into one. The most common 
mechanism is to add an MCIN block, set its IOMOPT to 0, and connect the two 
discrete inputs to one of its input parameters. FV would be attached to it.


Re: I want to pass some text string from main screen to faceplate screen i.e I 
have many similar objects in main screen

Yes. The P1, P2, P3 variables (and the PICK1 and PICK2 variables) can be used 
for this. To get the text into the variable, configure it to do this:

= PICK1 @

Or

= P1 @

This is take the text and store it into P1. Tie your FP/overlay to P1 and you 
should get what you want.

The difference is PICK1x get reset to "garbage" text when you change displays 
and Px does not.

Get a copy of B0193DF to see the full set of variables and commands.

Subject: [foxboro] FOXDRAW HELP PLEASE....

Hi there,
I am new to Foxdraw and I have the below two requirement which I am unable to 
execute/implement.
Need your help here.
1) I have created one indication object which has to change color on two 
conditions ( i.e Global variable x=1 or y=1 ). I know I can create two objects, 
overlap them and then give visibility. But what If I want to achieve this in 
one object only.
2) I want to pass some text string from main screen to faceplate screen i.e I 
have many similar objects in main screen.
When I click on any object, same faceplate would open. When I click on first 
object, the faceplate heading text has to be a1, When i click on the second 
object, the same faceplate would open with heading text as b1 and so on. Is 
there anyway i can pass this string a1, b1 etc through some variable and use 
this variable as animation in the faceplate.

Please help in the above two matter. Appreciate an early response on the 
subject.

Regards,
- Rakesh
