Refer to the Programming Guide for a detailed description of G groups and G functions.
With the 840 C, data can be read into the NCK circular buffer ("Execution from external") from
the hard disk and via the computer link file transfer. The device with which the data transfer is
executed is defined in the machine data (channel-specific 130* and 132*). The following
settings are possible:
Device type for Execution from external
130*
Default value
Lower input limit
Upper input limit

NC MD 130* defines the type of interface used to read in data for "Execution from external"
for each channel. The default value 0 defines the hard disk on the MMC.
Other possible values are:
MD 130* = 5 defines the computer link file transfer as the interface. The receiver has to be
defined in more detail in machine data 5148 to 5152 (see machine data description).
