The Engineering interface and the POS mimic

The POS mimic is rarely used, although it offers the facility to print the current configuration (File->Print) which can be useful while fixing fibreing problems at Prime Focus Access.

The tdfeng task is started from the aatlxy xterm with the imaginative command tdfeng. Take care to select Access Running and not Start System when bringing tdfeng up. A description of tdfeng is beyond the scope of this section. The user who is not familiar with it's use should defer to the night assistant if interaction with tdfeng is required.
