Chapter 2 The AADvance Safety Controller
equipment is not necessary. However, important consideration must be given
to the choice of cabinet or when the controller is installed in a hazardous
environment.
Specific guidelines are given in this user documentation to help you choose an
enclosure that will make sure that the system operates to its full capability and
reliability and that it also complies with the ATEX and UL certification
requirements for use in hazardous environments.
The Ethernet and serial ports are configurable for a number of protocols in
both simplex and redundant configurations for connection to other AADvance
controllers or external third party equipment. Communications internally
between the processors and I/O modules uses a proprietary communications
protocol over a custom wired harness. The AADvance system supports
transport layer communication protocols such as TCP and UDP for MODBUS,
CIP, SNCP, Telnet and SNTP services.
A secure network communications protocol (SNCP), developed by Rockwell
Automation for the AADvance system, permits distributed control and safety
using new or existing network infrastructure while ensuring the security and
integrity of the data. Individual sensors and actuators can connect to a local
controller, minimizing the lengths of dedicated field cabling. There is no need
for a large central equipment room; rather, the complete distributed system
can be administered from one or more computers placed at convenient
locations.
The AADvance controller is developed and built for IEC 61131 compliance and
includes support for all five programming languages.
Program access is secured by a "Program Enable" key that you can remove.
Simulation software lets you prove a new application before reprogramming
and downloading, again maximizing system uptime. Additional security
functions are also included to help prevent unauthorized access.
Safety Features The AADvance controller meets non-safety business requirements and SIL 2
and SIL 3 safety related system requirements. The system has comprehensive
built-in redundant capabilities that improve system availability.
The AADvance safety system features are:
• Easily transformed from a simplex non-safety system to a fault tolerant
safety related system.
IMPORTANT
AADvance® Workbench software version 1.4 supports the
Instruction List (IL) language.
AADvance Workbench software version 2.x and AADvance
®-
Trusted® SIS Workstation software do not support the IL
language.
ATTENTION: The AADvance Workbench software and AADvance-Trusted
SIS Workstation software do not support the Sequential Function Chart
(SFC) language for safety-related applications.
