Solutions Handbook (AADvance Controller)
Support for Variable Types
For each controller, you can declare variables using all types defined in IEC 61131-3,
including boolean, 16-bit integer (signed and unsigned) and 32-bit real. Controller-
specific types include structures to hold multiple variables for each I/O application.
Variables are easily imported from external databases if required.
Variables are defined in a data dictionary. The development environment provides a
hierarchical tree of variables and a grid-like representation of their definitions.
I/O Connection (Addressing of Physical I/O)
To establish the links between the hardware-independent logical variables of the
AADvance application program and the physical I/O channel available on the
controller, the AADvance Workbench provides a powerful I/O connection editor. I/O
channel links are easily defined between the logical programming and the I/O wiring
configuration. The I/O configuration can be tested separately from the application
execution such that each module can be debugged separately.
Any I/O device can be represented either as a single module or a group of redundant
modules. Different data types are accommodated. You can work directly on a pre-
defined I/O configuration, expand and change the configuration, and the workbench
fully supports directly represented I/O variables as described in the IEC 61131-3
standard.
Off-line Simulation and Testing
An engineer can validate a complete application off-line, without the target hardware
platform. The powerful simulator within the development environment can perform
structural and functional tests of each module and of the whole application.
Application (Resource) Program Security
The AADvance controller includes a Program Enable key that protects the
application from unauthorized access and change. The key must be fitted to the KEY
connector on the T9100 processor base unit before you can download and make
changes to an application (resource). The program enable key is supplied with the
processor base unit and is fitted as shown.
