6 Configuring with STEP 7 or a GSDML File
Note
If a value in the configuration data (I/O code, ID code, ID1 code, ID2 code) is not
F , the configuration data and AS-i parameters stored on the link will be
hex
overwritten by the values set here in STEP 7 while the PROFINET IO connection
is being established.
Selecting the I/O modules
If you do not use certain AS-i slaves, you can delete the corresponding I/O
modules. If you do not want to use the default configuration of the IE/AS-i LINK
with Bin.Slave 1 byte I/O modules, you can delete the existing I/O module and
replace it with a suitable one from the catalog. You then take an I/O module from
the hardware catalog and drag it to the required row.
You will find the slave modules in the HW Config catalog in PROFINET IO >
Gateway > IE/AS-i LINK PN IO > Double master or Single master. Various
modules for digital or analog values with inputs and/or outputs in sizes between 1
byte and 4 words are available.
For each AS-i slave that occupies more than 4 bits (for example analog slaves),
you can reserve I/O address space by selecting a suitable analog module.
(For a two-channel analog input slave, for example, the analog module
"Ana.Slave 2 words I" is suitable).
To configure the slave modules, open the "Properties Slave" dialog by
double-clicking on the row number of the relevant slave module in HW Config. In
the "Parameter" tab, you can change the IDs for this slave module (I/O code, ID
code, ID 1 code, ID 2 code).
Whether or not the IDs assigned in the properties dialog match the type of the
actually connected AS-i slave is not checked by STEP 7.
The advantage of individual configuration of the AS-i slaves is that the settings
from the configuration are transferred to the IE/AS-i LINK again every time the
PROFINET IO controller starts up and that you have documented the configuration
of the AS-i slaves in your STEP 7 project. Configuration also means use of less I/O
addresses.
For an overview of the various configuration options, refer to Section 2.2.
