Start program

This function is used to execute an external program (*.exe) from the Runtime. On executing the function transfer parameters for the application to start can be defined.

Give the program file (*.EXE) as the transfer parameter. This function is configured via a dialog mask.

Configurable options are:

Name	name of file which will be executed; search and select via button is possible
Parameters	transfer parameter for program
Open this dialog on runtime	changes program and parameter during online operation when function is called

The program is selected via a dialog mask.

For the start of a program it has to be in a search path (system environment under Windows NT). User-defined programs (Visual Basic) should be stored in the installation path of zenon.

When the alarm list is active and an alarm in the list has been selected, the call of the variables' name can be transferred as a parameter (for external database information systems). The parameter is transferred as a key word.

@alarm.name	Name of the variable
@alarm.unit	unit of the variable
@alarm.value	value, which violated a limit
@alarm.stext	limit text
@alarm.ctime	time comes (value in seconds since 1.1.1970)
@alarm.ctimemilli	with milliseconds
@alarm.gtime	Time cleared
@alarm.gtimemilli	with milliseconds
@alarm.qtime	Time acknowledged
@alarm.user	user, who quitted
@alarm.identification	Identification of the variable

If no alarm list is open, or several or no alarms are selected, no transfer parameters are generated. If several alarm lists are open (global or selective list), the entry of the first found list is used.

When the Chronologic Event list is active and an entry in the list has been selected, the call of the variables' name can be transferred as a parameter (for external database information systems). The parameter is transferred as a key word.

@cel.name	Name of the variable
@cel.unit	unit of the variable (only if a variable is linked)
@cel.value	value, which violated a limit (only if limit entry)
@cel.stext	limit text
@cel.ctime	time comes (value in seconds since 1.1.1970)
@cel.ctimemilli	with milliseconds
@cel.user	user, who quitted
@cel.identification	Identification of the variable

If no Chronologic Event List is open, or several or no entries are selected, no transfer parameters are generated. If several Chronologic Event Lists are open (global or selective list), the entry of the first found list is used.

Additional parameters are:

This function is used to to consider the effects of the started program on the system as a whole (required resources, multitasking, program stability, etc.).
