Settings for file handling in the part program for EES

Program names unique throughout the system
If external program memories are used together at different stations in EES mode, file
operations performed simultaneously on different stations (WRITE, DELETE, ...) result in
access conflicts. To avoid such access conflicts, we recommend setting up a name space for
file names on each station that is unique throughout the system.
Name space unique throughout the system
A name space for file names that is unique throughout the system is achieved, for example,
by associating the file names with the EES-specific name of the NC parameterized in the
machine data and the channel number of the channel in which the program is executed. For
example, when the program is executed, the following code generates the file name (MYFILE
_NC1_1.SPF), which is unique throughout the system, by appending the EES-specific name
of the NC (NC1) and the channel number (channel 1) to the program name.
$MN_EES_NC_NAME="NC1"
N10 DEF STRING[31] FILENAME
N20 FILENAME="MYFILE_" << $MN_EES_NC_NAME << "_" << $P_CHANNO <<
".SPF"
Parameterization
The EES-specific name of the NC is set in the NC-specific machine data:
