MD 540* Output auxiliary functions to PLC
This signal has to be set for all channels, for which auxiliary signals concerning tool
management are output.
MD 544* Bit 4 Output of the T auxiliary function in binary code (0 = binary, 1 = BCD code)
The signal must not be set because the standard tool management processes the T
number as a fixed-point number.
MD 544* Bit 5 Output of the D auxiliary function in binary code
The signal must not be set since the standard tool management processes the D
number as a fixed-point number.
MD 544* Bit 6 Output of the H auxiliary function in binary code
Binary if routed to FB 133 (0 = binary, 1 = BCD code)
