2.3.2 Changing the entry values via PLC
The entry values of the active machine parameter list can be changed with the module 9031 (see
chapter "PLC Programming", section "PLC-modules"). These changes are then erased when the TNC
is switched off.
The machine parameters which can by changed through the PLC are marked in the following list
with PLC EDIT or PLC RUN. PLC EDIT means that the machine parameters can only be changed if
no program is being executed on the machine. PLC RUN means that the machine parameter can be
changed even while a program is being executed.
