Activating components

Machine data for the PLC I/O
The following components are assigned fixed addresses for the input and output image of the
PLC: I/O modules, machine control panel, SENTRON PAC and PN/PN coupler.
To deactivate the update of the input and output images of the PLC, set the following machine
data:
Machine data
12986[i]
12987[i]
The SINUMERIK 828D works with a fixed maximum configuration of the I/O modules. As
delivered, the data transfer to the input and output image of the PLC is deactivated for all I/O
modules.
To activate a PN component, you must enter the value -1 ("empty") in MD12986[i], see the
table in Section Addressing components (Page 239). MD12987[i] is preset with the value -1
and must not be changed.
Machine control panel
To activate the machine control panel, check the setting of the following machine data:
