About us
Introduction
The Transparent Ready service classes make it possible to identify the services provided by each device, such as:
Web Service Classes
The four Web service classes are defined by letter:
Transparent Ready devices with an embedded Web server can provide four types of Web service:
NOTE: The availability of Web service classes depends on your choice from the standard and optional memory cards.
This table specifies the services provided by each Web service class (A, B, C, D):
Web Server Class

  • SOAP/XML (client/server)
  • user-defined states

Ethernet Communication Service Classes
The Ethernet communication services provided by devices are (identified by number):
Transparent Ready devices can provide these Ethernet communication services:
The following table specifies the services provided for each Ethernet communication service class:

Choosing Transparent Ready Devices
Transparent Ready devices are chosen from four main families:
The services provided by a given Transparent Ready device are identified by the level of Web service (a letter) followed by the level of Ethernet communication service (a number). For example:
NOTE: Service classes are incremental subsets. That is, class D includes all the services in class C, and class C includes all the services in class B. (Class A has no services.)
The selection table on the following pages can be used for choosing Transparent Ready devices according to the required service classes:
