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:
•
Power 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 redirection)
•
Panel locking mechanism (configurable using the B&R Control Center - ADI driver)
•
Backlight control of a connected B&R display
•
Calculation of statistical data (power cycles - every switch-on, power-on and fan hour is calculated, data
is updated at 15-minute intervals)
•
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 based on the existing hardware.
The functions of the MTCX can be extended by upgrading its firmware

. The version can be read in BIOS or with
the B&R Control Center in approved Microsoft Windows operating systems.
