Transparent Communication Interface (TCI)
The AADvance controller processor module provides a Transparent Communications
Interface (TCI) function. This functionality will establish a pass-through
communications link between an Ethernet link to a Serial port allowing devices
attached to a serial port to be communicated with and for them to reply. The
controller does not tamper with or inspect the data passed over the channel.
TCI uses a TCP port number to represent a serial port. All six serial ports are
represented by each controller, so any serial port can be reached from any controller.
Traffic is routed through TCP to the relevant serial port and in reverse. However, TCI
communication from the serial ports is only available when the controller is not
executing an application.
Users can enable and disable the function and set the Inactivity Timeout and Idle Time
values.
Important Note: To use the TCI function you must stop the resource. This will
have a serious effect on a Safety Related application.
Compiler Verification Tool
The Compiler Verification Tool (CVT) is a software utility that validates the output of
the application compilation process. It is automatically enabled for resources when a
project is created and when you add a resource to an existing project. This process in
conjunction with the validated execution code produced by the AADvance
Workbench confirms that there are no errors introduced by the Compiler during the
development of the application.
To achieve this CVT decompiles the application project file and then compares each
individual application project (POU) source files with its decomposed version. The
CVT analysis is displayed in the Workbench window.
