5.5.13 Assigning I/O addresses to the NCU machine data
Procedure
To
enter addresses which have been configured in the TIA Portal in the machine data, proceed
as follows:
1. Check in the TIA Portal which addresses you have assigned to the I/O modules
(see Configuring IO modules or drive telegrams (Page 106)).
2. Transfer the addresses to the following machine data (e.g. via SINUMERIK Operate):
MD Identifier Description Concerns the mod‐
ule type
105
00
$MN_DPIO_LOGIC_AD‐
DRESS_IN
Logical slot address of the PROFIBUS/
PROFINET I/O
Input module
105
01
$MN_DPIO_RANGE_LENG
TH_IN
Length of the PROFIBUS/PROFINET I/
O range
Input module
105
10
$MN_DPIO_LOGIC_AD‐
DRESS_OUT
Logical slot address of the PROFIBUS/
PROFINET I/O
Output module
105
11
$MN_DPIO_RANGE_LENG
TH_OUT
Length of the PROFIBUS/PROFINET I/
O range
Output module
Use machine data with the same index in order to enter the address and the associated
address length of a module. Use, for example, for the address of an input module,
MD10500[1] and for the address length of the same module MD10501[1].
Example
The following example compares the configuration in the TIA Portal and the compared values
in the machine data:
