Use of macros during the command entry in PLC-Browser

If a command associated with a macro is entered in the command line, this is expanded before it is sent to the controller. Then the response in the result window appears in a similarly expanded form.

The entry syntax is: <KEYWORD><macro>

<KEYWORD> is the command.

Macros

%P<NAME>	If NAME is a POU-name, the expression is expanded to <POU-Index>, otherwise there is no alteration
%V<NAME>	If NAME is a variable name, the expression is expanded to #<INDEX>:<OFFSET>, otherwise there is no alteration (this notation #<INDEX>:<OFFSET> is interpreted by the controller as a memory address)
%T<NAME>	If NAME is a variable name, the expression is expanded to <VARIABLENTYP>, otherwise there is no alteration.
%S<NAME>	If NAME is a variable name, the expression is expanded to <SIZEOF(VAR)>, otherwise there is no alteration.

The % character is ignored if the escape symbol \ (Backslash) is placed in front. The escape symbol as such is only transmitted if written \.

Example

Entry in command line: (memory dump of the variable .testit ?)

mem %V.testit

Output in result window:

mem #4:52
