1 byte for data set 1 is available for every expansion module. The input values show the state of the prelim-
inary evaluation of the I/O module. This corresponds to the state of the element in the controller module lo-
gic. The level at the associated terminal cannot be clearly detected from this, as the data may be set to low,
irrespectively of the level at the input terminal, by means of the cross-connection detection or two-channel
evaluation (e.g. I1-18).
When two-channel input elements have been configured for an I/O module, only the lower-value bit repres-
ents the pre-evaluation state of the corresponding element (e.g. bit 0 for I1 and I2, bit 2 for I3 and I4, bit 4
for I5 and I6, bit 6 for I7 and I8).
The higher-value bit (bit 1, 3, 5 and 7) is used as follows in this case:
0 = error, 1 = no error

Data from the PLC to the MSI 430 module
There are 5 output data blocks having 10 bytes each. These can be exclusively placed in each correspond-
ing slot 21 to 25.
The content of these data blocks can be used as input in the MSI.designer logic editor or forwarded to an-
other network by a second gateway. Every bit to be used must be assigned a tag name in order to provide
the desired bits in the logic editor or for forwarding. Bits without tag names are not available.
Detailed information about how you can assign and adapt the tag names of the input and output data can
be found here:
Software manual, chapter "Adapting display names of project components"
NOTICE
i
The standard value of the gateway data bit is zero following activation of the MSI 430 device.
If the connection to PLC is terminated, then all of the gateway data bits in the MSI.designer logic
editor assume the value zero.
NOTICE
i
For output data with IOPS=Bad, all of the gateway data bits in the MSI.designer logic editor as-
sume the value zero. This is the case, for example, if the PLC is stopped.
Settings in the PROFINET IO network configuration tool
Ä Only drag the required data blocks from the hardware catalog of the SIEMENS TIA Portal to the corres-
ponding slots of the MSI 430 module within the configuration table.
