8.8 Scripting with VBS and ANSI-C
Runtime
The performance data can also be influenced by the following factors:
●
Hardware used
●
Type of configuration
● Running processes, for example, Tag Logging or Alarm Logging
The following measured vales indicate the difference between VB scripting and C scripting
based on the comparison of orientation values.
The following configuration was tested as typical scenario:
Typical configuration
For example: Windows 7 (64-bit), Intel Core i7-2600 (3.4 GHz), 8 GB RAM
The measured values are specified in milliseconds.
VBS ANSI-C
Set color of 1 000 rectangles 220 1 900
Set output value of 200 I/O fields 60 170
Select a picture with 1 000 static texts which determine the
object name and issue it as return value

Read 1 000 internal tags 920 500
Re-read 1 000 internal tags 30 120

VBS
For i=1 To 100000
value=Cos(50)*i
Next
ANSI-C
for(i=1;i<=100000;i++)
{
dValue=cos(50)*i;
