VisAM Win32 Modulediscription

The VisAM Editor:

The editor consists of different applications for the building and editing of VisAM projectfiles. It is not necessary for onlinemode of those applications. In the editor you can design your processimages with many different types of graphical fields, allocate the VisAM communication channels with drivers for your remotesystems or link your project with external scriptfiles.

VisAM provides you the following fieldtypes for your applcation:
Media, Label, Form/Color-switch, Switch / Bitswitch, Dezimal, analog beam, Messagetext, Menu, Call-up, Application-end, Safe (recipe), Load (recipe), Delete (recipe), ASCII string, Line animation, Button, ProFormat, Symbol animation, linediagramm, Image, key-transfer, Database Report, Journal, Circlepointer, Time, Date, Text report, Message statistic, Table

VisAM Datafield (VDF)

All processdata in VisAM Win32 will be exchanged by processvariables (PV) of the VisAM datafield (VDF)!

The VisAM datafield is the "bridge" between all VisAM functions an the connectet remotestations. This structure provides huge advantages e.g. for remote controlling or remote maintance, because all processdata in VisAM are present at the same time. All data are exchanged automatical betwenn VOK and VKK according to the definition in the VDF. The communication channels (VKK) handels the datatransport from/to the remotestations.

The datawith of the processvariables (16bit) was chosen because of compatibility to common remotestations (mostly PLC-Systems). But it´s possible to combine multiple datapackages e.g. to describe a 32bit package.

The processvariables (PV) in the VDF are organised in 256 groups with 256 PVs per group. (Similar to S5-Systems: 256 groups = 256 DB, 256 PV = 256 DW).
This gives you an amount of 65536 PV.

The VisAM Online-Communicationmanager (VOK):

The VOK is the runtime module and is the most important part within our SCADA-System. Via his 10 communication channels (VKK) it starts the assigned communication modules (VKM), it handels all access to the VisAM Datafield (VDF), controlls the refreshing of the variables (PV) and the graphical user interface etc.

The HTML-Service-Interface:

This interface generates HTML based process images and controlls the automatic transfer to a local directory or to a FTP-Server.
The HTML-Service-Interface is a simple and costeffective visualisation for network/intranet or internet. You can display the images with your common internet browser e.g. MS Internet Explorer (Version 4 or higher), Netscape Navigator, Firefox etc. Assumption: JavaScript must be enabled!

The alarm system :

The VisAM Win32 alarm system provides different possibilities for message dispatch:
The basic alarm system administrates 4096 different messages simultaneous. Every single message has a message bit and an optional quit bit and feedback bit.

The message manager:

The VisAM message manager (NMG) enables the dispatch of messages by SMS, Email, Fax or network.
The application works self-sufficient in the background. The functioning is similar to VisAM and it is controlled by VisAM script commands. The message lenght is limited to 160 chars. Once the message manager is configured, it is ready for usage.

VisAM script editor:

The VisAM script editor assists you in building project base applications, so called scripts. The script language is called VisAM-VB-Script, a extended version of Microsofts VB-Script with VisAM spezific commands.

The script editor was developed to ease the handling of VB-Script in association with VisAM. It encapsulate scripts into single and independent working files which results in a easy to use solution for a complexe theme.

Every VisAM application can be extended by one or more (Pro version only) programmes (scripts). Those scripts are closed and independent functions that can be activated on every cycle or on a single event. Special functions enable access to all process variables in the VDF. The values are automativally transformed to the right format.
