PLC functions for HMI

Program selection from the PLC
Function
Preselected programs/workpieces can be selected for machining by the NC via the PLC/HMI
interface.
The preselection is realized by entering programs/workpiece in files (these are known as PLC
program lists (*.ppl).
Preconditions
The following machine data must be set to allow the HMI to process tasks:
MD9106 $MM_SERVE_EXTCALL_PROGRAMS
In order to activate a sector-specific PLC program list, you must set the appropriate machine
data and at least the protection level password:
● Area User
– MD51041 $MN_ENABLE_PROGLIST_USER = 1
– Protective level password: 3 (users)
– Program list: /user/sinumerik/hmi/plc/programlist/plc_proglist_user.ppl
● Area Manufacturer (OEM)
– MD51043 $MN_ENABLE_PROGLIST_MANUFACT = 1
– Protective level password: 1 (manufacturer)
– Program list: /oem/sinumerik/hmi/plc/programlist/plc_proglist_manufacturer.ppl
Structure of a program list
A program list is a text file. Each line contains the following information:
<program number> <program path><program name> [CH=<channel number>]
● Program number
The program numbers which may be used in a program list depend on the sector:
– user: 1 - 100
– Individual (oem_i): 101 - 200 (only SINUMERIK 828D)
– Manufacturer (OEM): 201 - 255
● Channel number
Specifying the channel number "CH=<channel number>" is optional. It is only required if
the NC has more than one channel.
