During commissioning of the control the machine parameters and the compensation table can be
transferred to the RAM memory with the COPY ROM⇒RAM soft key (only with TNC 406). They
become active the next time the control is started.
The PLC program can also be transferred to the RAM memory with the COPY ROM⇒RAM soft key
(on TNC 406) or the TRANSFER PROGRAM FROM EPROM soft key (on TNC 306).
Machine parameter MP4010 selects whether the PLC program is run from the RAM area of the
control or the EPROM area.
During the creation and test of the PLC program the control should operate from the RAM area.
HEIDENHAIN recommends that an EPROM is created for the PLC-program before delivering the
machine to the customer (see also Chapter "Introduction").
