This command sets a Default Motion Element (axis or group) that replace previous WITH statement, sets on the CONFIG.PRG file, or didn't exist at all.
Like the "WITH" statement, the motion element will operated without having to explicitly indicate the motion element name.


The default motion element exists only after a WithGlobal statement, which can be terminated in three ways:

  • New WithGlobal statement, declared in every scope.
  • "reset all" command applied within the Terminal.
  • Local With that valid only as the local task runs.


NOTE-Info.svgNOTE
Unlike using local/Terminal WITH statement - which require With..... → End With methods, when using the "WithGlobal" statement, there's NO need to declare "End WithGlobal".

Syntax

WithGlobal <element name>

Availability

4.17.6

Scope

Configuration, Task or Terminal

  • In the Terminal scope, the specified motion element becomes the default motion element for the system, that replace ALL previous WITH - CONFIG/WITHGLOBAL statement, from all scopes.
  • The way to "kill" a WithGlobal statement that was declared, is to use reset all command, and change the Config.prg file as you wish – or to issue another WithGlobal command..

Limitations

  • WithGlobal commands can't be nested, As there is noEnd WinthGlobal statement.

Examples

 1 A1.VMax=5000
 2 
 3 A1.Vord=5000
 4 
 5 A1.VCruise=3000
 6 
 7 A1.PEMax=10
 8 
 9 A1.PESettle=0.01
10 
11 Move A1 100
12 
13 A2.VMax=5000
14 
15 A2.Vord=5000
16 
17 A2.VCruise=3000
18 
19 A2.PEMax=10
20 
21 A2.PESettle=0.01
22 
23 Move A2 100


Can be simplified using:


 1 WithGlobal A1
 2        VMax=5000
 3        Vord=5000
 4        VCruise=3000
 5        PEMax=10
 6        PESettle=0.01
 7        Move 100
 8 
 9 Withglobal A2         'replace the previous "WithGlobal" statement 
10        VMax=5000
11        Vord=5000
12        VCruise=3000
13        PEMax=10
14        PESettle=0.01
15        Move 100
