Introduction

The ADS-Script-DLL permits access to ADS devices from script languages (VBScript or JScript). Script languages are used by the Windows Scripting Host (WSH) and in the creation of interactive internet applications. The scripts can be executed either on the web server (active server pages) or at the client (DHTML, ...).

Because the script languages only support a small number of data types, a corresponding method exists in the ADS device for every possible data type. This reduces the number of parameters to a minimum. The methods in which a variable is accessed by name (TcScriptSync::ReadVar() and TcScriptSync::WriteVar()) form exceptions to this rule. In these cases the ADS variable data type is found from the ADS device. Both methods convert the parameters internally into the associated data types before making their access to the ADS device.
