5.3 Incompatibility
It has not been possible to maintain compatibility in all areas of the PLC programs. This is because
the TNC 355 differs considerably from the TNC 407 and TNC 415 both in memory organization and
ergonomics.
5.3.1 PLC Macros
The following macro programs are available in the TNC 355 for controlling the tool changer.
M3264 Convert tool number or pocket number to binary code
M3265 Increment actual value of pocket number
M3266 Decrement actual value of pocket number
M3267 Compare actual and nominal values of pocket number
These macro programs are no longer available in the TNC 407 and TNC 415. The following PLC
subroutines can be used in place of the macro programs.
Convert tool number or pocket number to binary code
