Entering a program with the GOTO key
If you use the GOTO block number key for going into a
program, neither the TNC nor the PLC will execute any
functions that ensure a safe start.
If you use the GOTO block number key for going into a
subprogram, the TNC will skip the end of the subprogram
(G98 L0)! In such cases you must always use the
mid-program startup function.
