The APAX-5000 series of PACs integrates control, information processing and networking in a single control system with a unique dual-controller architecture, says the vendor.
They consist of controllers, I/O modules, backplanes and power modules.
Two standalone CPU modules working together are responsible for
different tasks. One provides high computing power for HMI/SCADA,
recipe, database and communication tasks while the other is dedicated
for SoftLogic I/O tasks. The controllers also support back-up
functions. The same I/O processing program can be stored on two
controllers, one will execute the I/O processing and if that controller
fails, the second controller will automatically take responsibility for
I/O processing within 1.5 seconds. The I/O modules are well-equipped to
be either local I/O or remote I/O through their Ethernet bus backplane.
They offer one- and two-slot backplanes, (APAX-5001 and APAX-5002).
Each APAX-5002 backplane offers one expansion port. A remote expansion
with local-bus speed is built with a distance up to 100m.Advantech Corp., Industrial Automation Group www.advantech.com/ea800.205.7940
