Changing over from following to individual operation and vice versa. (copy
from the virtual keyboard).
Effect in the NC: Processing of a program either continuously (following
block) or block by block (individual block).
0 = following block; 1 = individual block

Data word 138.00−15: signal state "1" indicates that the corresponding CAN
module is available.
Data word 139: A value unequal to 0 means that an error has occurred in con-
nection with the CAN modules.
Effect in the PLC: Option of monitoring the CAN modules.

Program stop
NC

PLC
static
Image of the "Stop" key. The signal has value "1" for as long as the informa-
tion in the virtual keyboard of the NC has value "1". Value "1" is used to
request the termination of a running program or a traversing movement.
The meaning depends on the set operating mode.
Manual operation: termination of the currently running movement
Automatic: termination of the currently running program
Effect in the PLC: When value "1" is recognized, the "Program stop" signal
(DW 012.XX) is set after checking any other possible existing conditions.

Feed stop
NC

PLC
static
Image of the "Feed stop" keys. It has the value "1" for as long as the informa-
tion in the virtual keyboard of the NC has the value "1". The value "1" re-
quests the axes to stop without canceling the program or a traversing move-
ment.
Effect in the PLC: If the value "1" of the signal is detected and after any other
existing conditions have been checked, the PLC withdraws the "Feed enable"
signal for all axes. Feed enable must be restored in the case of "Program
start" and "Start after feed stop".
