1 Maintenance Controller Extended (MTCX)
The MTCX controller (FPGA processor) is located on the mainboard (part of every system unit).
MTCX
Figure 226: MTCX controller location
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 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 (USB forwarding)
•
Daisy chain display operation (touch screen, USB forwarding)
•
Panel locking mechanism (can be configured using B&R Control Center - ADI driver)
•
Backlight control for connected B&R displays
•
Statistical data recording (power cycles - records every switch-on, power on and fan hour; each full hour
is counted, i.e. not increased at 50 minutes)
•
SDL data transfer (display, matrix keyboard, touch screen, service data, USB)
•
LED status indicators (HDD, Link, Run)
Extended MTCX functions are available by upgrading firmware
1))
. The version can be read in BIOS ("Advanced"
- Baseboard/Panel Features) or in approved Microsoft Windows operating systems with the B&R Control Center.
1.1 Temperature monitoring - Fan control
The MTCX constantly monitors the temperature using temperature sensors, which directly determines how the
fans are controlled. The speed depends on the measured temperature. The limit values depend on the MTCX
firmware version being used.
