13.2.4.1 C167 controller board
The controller program (firmware) on the C167 controller board is saved in a flash EPROM. The
version number can be queried from the SITEST program.
The machine data and the set-up are saved in RAM. After the machine is switched off, the data is
held by a buffer battery (buffer time approx. 3.5 years), which is also located on the C167 controller
board. In addition, an electrolytic capacitor ("Goldcap") with a capacity of 1 F is fitted. This saves
the data for approximately 8 hours when the buffer battery is changed.
The "neutral position" light barriers and the software limit switches are wired to the Masterdrives
and are made available there via the CAN bus of the controller.
Tasks:
– Communicating with the station computer of the SIPLACE station
– Controlling the machine via the firmware
– Exchanging data with the axis controllers
– Saving the firmware (flash EPROM)
– Saving the machine data and the set-up (battery-buffered RAM)
– Saving machine-specific parameters, such as serial numbers (in the EEPROM)
– Providing a realtime clock
– Inputs for sensors
– Displaying operating statuses and error statuses via LEDs
