Deactivation of the PROFINET IO function

If the MSI 430 device is started with an activated PROFINET IO function, then this function remains active
until the device is switched off.
For this reason, switch the device off after sending a project without PROFINET IO function. This is re-
quired, for example, if you convert the gateway function in the MSI 400 project from PROFINET IO to Mod-
bus TCP.

State bits

The PROFINET IO gateway MSI-EN-PN sets state bits, which are available in the logic editor of MSI.de-
signer for processing.

Internal state
An Application Relation (AR) is a clear communication relationship between two communication partners,
for example a PLC and a device. The AR is initialized during PLC start-up. Cyclical input and output data,
acyclical data using read/write services and alarms are exchanged bidirectionally between the PLC and the
device within this AR.

Optimizing performance

Only use the data blocks from the hardware catalog of the module that you actually need for your applica-
tion.
Sequence the process data in the routing tables within a data block without gaps (see Layout and content
of the tabs [chapter 5.1.3]). Then check whether this will enable you to do without the use of individual data
blocks from the hardware catalog. This helps to reduce the number of data bytes periodically exchanged in
the network.

Possible cause
• The MSI 430 module is
not properly connected
to the MSI 400 modules.
• The module connection

Red
Set to 1, if ...
... Data from slot 16, 17, 18, 19, 20,
32 or 33 was transmitted without er-
ror.
... Data from slot 21, 22, 23, 24 or
25 was downloaded from a PLC
without error.
... An AR (Application Relation) is
active.
Possible remedy
• Insert the I/O module cor-
rectly. Clean the connection
plug and socket.
• Switch on the power supply
again.
• Check the other MSI 400
modules.
