Commissioning; Preconditions - Siemens SINUMERIK 840D sl Function Manual

K1: Mode group, channel, program operation, reset response
9.15 EES (optional)
● A network drive provided through Windows
● Statically managed USB drive
The EES function can replace the "Execution from external (Page 598)" and "Executing
external subprograms (EXTCALL) (Page 600)" functions.
The EES function has the following advantages:
● Standard program handling throughout the system
● No restrictions regarding the commands that can be used
The restrictions on "execution from external source" and "execution of external
subprograms (EXTCALL)", e.g. no backward jumps, limitation of the jump distance of jump
commands by the size of the reload memory, are eliminated with EES.
● Programs can be moved between different program memories (NC, GDIR, external drive)
significantly easier.
● There are practically no restrictions regarding the part program size (this is only limited by
the capacity of the external data storage).
● Uniform syntax for the subprogram call, independent of the storage location of the
subprogram (an EXTCALL call is not required).
● Network drives can be used jointly by more than one station (PCU/NCU). Prerequisite is a
uniform drive configuration for these stations. This results in a uniform view of the programs
for all stations.
● Because of the uniform view of the external program memory for all stations, changes to
the programs stored there consistently apply to all stations.

NOTICE
Tool/workpiece damage caused by the USB FlashDrive
A USB FlashDrive cannot be recommended when executing an external program. A
communication interruption to the USB FlashDrive during the execution of the program
due to contact problems, failure, abort through trigger or unintentional unplugging, results
in an uncontrolled stop of the machining. The tool and/or workpiece could be damaged.
