14.2.5 Modules of the controller
14.2.5.1 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 backup 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
Two RS232 interfaces (maximum transfer rate: 115.2 kBaud/s)
COM 1: Test interface for debugging service
COM 2: Free
