Enabling Project Efficiency
System Backup Functions
APAX-5000 series delivers system backup functionality. To leverage this functionality,
two controllers with the same control program, are installed in one system. After both
controllers' backup function is enabled, the APAX-5000 system will automatically delegate
one of the two controllers as the master controller.
The control program should use the function block "AdvRdSysActiveState” to know
if its controller is the master controller currently, by the parameter Value. If the Value
responses "True", it means the controller is master controller, then the program should
execute the control algorithm. If the Value responses "False", it means the controller is
backup controller, then its program should do nothing, and simply checking if the master
controller is still alive periodically. When it detect the master controller is lost, it should
executing the control algorithm, making it become the master controller.
Motion Control
PLCopen for Advantech PAC
Advantech offer motion function blocks which follow PLCopen standards. They can help
system integrators to easily perform point-to-point moves, continuous moves, linear
and circular interpolation and homing functionality. With the PLCopen-compliance FB,
system integrators can benefits from reduced hardware cost and fully utilizing PC's high
computing ability. The programmed application can be migrated to different hardware
platforms in another machine development cycle.
Modbus Driver
Advantech has provided an interface to monitor and control tags. This interface is
accessible via Modbus/TCP as well as Modbus/RTU .The APAX controller can be treated
as a Modbus Slave.
The APAX Controller reserves approximately 128K Bytes memory space for Modbus use.
This shared memory block can store user’s data and exchange the data through Modbus/
TCP and Modbus/RTU protocol with a HMI/SCADA software.
Utility for Advantech PAC
Each Advantech PAC controller has a built-in utility. System integrators can browse what
modules are connected from the tree view interface. For different I/O modules, you can test
I/O functionality, debugging if the module can work normally or not, and pre-setting some
preferable parameters, such as type and range for analog I/O modules. Even you choose
IEC 61131-3 programming tool, Advantech also provides the easy-to-setup window-type
configuration tool under KW’s SoftLogic software. It’s quite helpful for integrators before
starting to program the whole system.
HMI Software
PM Designer 2.0
HMI Runtime Development Software
PM Designer is powerful yet intuitive software to create total solutions for Windows XP ,
XPe and CE OS platform products. PM Designer is an easy to use integrated development
tool. The features include solution-oriented screen objects, high-end vector graphics,
Windows fonts for multi-language applications, recipes, alarms, data loggers and operation
logging. PM Designer also includes online/offline simulation and other utility programs
such as Data Transfer Helper (DTH); recipes editors and text editors (Refer to 1-2).
Panel Express runtime, a part of PM Designer, guarantees reliability and performance of
WOP Series HMI & APAX 5000 PAC controller because of the minimum system overhead,
high communication data rates, sub-second screen switching, and 24/7 operation.

Advantech WebAccess
Browser-based HMI/SCADA Software
Advantech WebAccess is browser-based software package for human-machine interfaces
(HMI) and supervisory control and data acquisition (SCADA). All the features found in
conventional HMI and SCADA software packages are available in an ordinary browser
including Animated Graphics Displays, Real-time Data Control, Trends, Alarms and Logs.
WebAccess is based on standard Internet architecture, its basic components include
SCADA Node, Project Node, Client and Thin Client (Refer to 2-4).
