A.1 Maintenance Controller Extended (MTCX)
The MTCX controller (FPGA processor) is located on the mainboard (component of every system unit) of the
APC3100 and PPC3100 device.
MTCX
The MTCX is responsible for the following monitoring and control functions:
• Switching on (power OK sequencing) and power failure logic
• Watchdog handling (NMI and reset handling)
• Temperature monitoring
• Fan control
• Key and LED handling/coordination (matrix keyboard of B&R display units)
• Advanced desktop operation (keys, USB redirection)
• Daisy chain display operation (touch screen, USB forwarding)
• Panel locking mechanism (configurable via the B&R Control Center - ADI driver)
• Backlight control of a connected B&R display
• Calculating statistical data (power cycles - each switch on, power on and fan hours are calculated - each
1/4 hour is counted)
• SDL data transfer (display, matrix keyboard, touch screen, service data, USB)
• LED status indicators (Power, Disk, Link, Run)
• Optimal default BIOS settings are reported to BIOS by the MTCX depending on the existing hardware.
The functions of the MTCX can be extended by upgrading the firmware
approved Microsoft Windows operating systems using the B&R Control Center.
