Groups
The language commands are subdivided into the following groups:
Group 35
The actual punching and nibbling-specific functions are activated and deactivated by means of the
following language commands:
PON
SON
PONS
SONS
SPOF
Group 36
This group includes the commands which have only a preparatory character and which determine the
real nature of the punching function:
PDELAYON
PDELAYOF
Since the PLC normally needs to perform some preliminary tasks with respect to these preparatory
functions, they are programmed before the activating commands.
Group 38
This group contains the commands for switching over to a second punch interface. It can be used, for
example, for a second punching unit or set of hammer shears. A second I/O pair which can be used
for punching functionality is defined via machine data.
SPIF1
SPIF2
Note
Only one function at a time can be active within a G code group (similar, for example, to the
various interpolation modes G0, G1, G2, G3, etc. which are also mutually exclusive).
