3. Maintenance Controller Extended (MTCX)
The MTCX controller (FPGA processor) is located on the main board (part of every system unit)
of the APC620 device.
The MTCX is responsible for the following monitoring and control functions:
• Power on (power OK sequencing) and power fail logic
• Watchdog handling (NMI and reset handling)
• Temperature monitoring (I/O area, power supply, slide-in drive 1/2)
• Fan control (3 housing fans)
• Key handling / coordination (matrix keyboard on Automation Panel 900 devices
configurable using B&R Key Editor, PS/2 keyboard)
• LED handling (matrix keyboard with LEDs on Automation Panel 900 devices configurable
using B&R Key Editor)
• Advanced desktop operation (keys, USB forwarding)
• Daisy chain display operation (touch screen, USB forwarding)
• Panel locking mechanism (configurable using B&R Control Center - ADI driver)
• Backlight control for a connected B&R display
• Statistical data recording (power cycles - each power on, power on and fan hours are
recorded - every full hour is counted e.g. 50 minutes no increase)
• SDL data transfer (display, matrix keyboard, touch screen, service data, USB)
• Status LEDs (HDD, panel lock, Link 1, Link 2)
The functions of the MTCX can be expanded via Firmware upgrade
1)
. The version can be read
in BIOS (menu item "advanced" - baseboard/panel features) or in Microsoft Windows
XP/embedded, using B&R Control Center.
