TNC 407/TNC 415/TNC 425 6 Display and operation 01.98
6.13.1 Decimal sign
The decimal sign can be selected by machine parameter.
MP7280 Decimal sign
Entry: 0 or 1
0 = Decimal comma
1 = Decimal point
6.14 Memory test
A machine parameter can be used to select if the RAM and the EPROM memory areas should be
tested on switching on the control.
MP7690 Memory test at switch-on
Entry: %xx
Bit 0 RAM-test 0 = memory test at switch-on
Bit 1 EPROM-test 1 = no memory test at switch-on
6.15 End of program
In the operating modes "Program run/single block" or "Program run/full sequence", if the end of the
program is reached the NC sets the marker M2061. This marker is only reset at the start of the next
program.
The information "End of program" can be evaluated by the PLC. This is necessary when operating,
for instance, with a pallet-changer.
Marker Function Set Reset
M2061 END PGM, M02 or M30 has been executed NC NC
6.16 Overwrite Q-parameters
The values in the Q-Parameters Q100 to Q107 can be overwritten by the PLC. In this way
information from the PLC can be transferred to the machining program. The value which is to be
transferred is stored in Doubleword D528. The Q-parameter which is to be overwritten is defined in
Word W516. The transfer is initiated by the strobe-marker M2713 during an M/S/T strobe.
The Doubleword D528 has a multiple usage. See also the sections "PLC positioning" and "Datum
shift correction".
