Data received from the network (network output data
sets)
The data received from the network are organised in output data sets (max. 50 bytes).
These data have been subdivided in five data blocks holding 10 bytes each for the
FX0
R
GENT, FX0-GMOD, FX0-GPNT, FX0-GETC and the FX0-GDEV. For the FX0-GPRO output
data blocks 1-4 hold 12 bytes each while output data block 5 holds 2 bytes. The FX0-GCAN
has four process data objects (PDOs) with 8 bytes each.

The contents of the output data blocks can be used within the FX3-CPUx logic editor and
can also be made available to another network via a second Flexi Soft gateway in the Flexi
Soft system.
In order to make the data from the network available in the logic editor or as input to
another network, you must define a tag name for each bit that shall be used.
Bits without a tag name will not be available in the logic editor nor for routing via a
second gateway. For detailed information on how to define tag names for the data
received please see the related section in the chapters on the different gateways.
The status of the communication to and from the network can be monitored in the logic
editor using the module input status bit for data from the network and the module out-
put status bit for data to the network. When the gateway detects an invalid communica-
tion, the contents of the data sets will be set to zero (logical 0) and the corresponding
module status bit will also be set to zero (logical 0).
In case all communication is dropped, the data of the output data sets will be set to
zero (logical 0) and the module input status bit will also be set to zero (logical 0).
If a connection is closed while still others are available, the MS LED or the STATUS LED
on the related gateway flashes
Red/green for 10 s and an entry is made in the error
history. In this case, the status bits will not be affected.
Do not use the same output data set number for two different PLC connections or
TCP/IP sockets!
The output data set can be written to the Ethernet gateways in parallel by all communica-
tion interfaces or TCP/IP sockets (e.g. Modbus TCP and Ethernet TCP/IP), if they use the
same output data set number. In that case, the last message overrides data received
earlier.
