2.5.4 Transferring Data
The sample ladder logic automatically updates the data with the
FLNETDATA.Output
and
FLNETDATA.Input
controller tags. The Area 1 data is
divided into blocks 1 to 3. The Area 2 data is divided into blocks 4 to 35. Each
block contains up to 240 words of data.
The data received from the remote FL-net node to the MVI56E-FLN module is
automatically "reassembled" from the input blocks into the
FLNETDATA.Intput
controller tag (according to each block ID). Also, the data to transfer from the
module to the remote FL-net node is copied from the
FLNETDATA.Output
controller tag into the output blocks according to its block ID. This logic is already
handled by the sample ladder program supplied by ProSoft.
For this example, use the following MVI56E-FLN Area1 and Area 2 settings in
the FLNET.CFG configuration file:
Area 1 Top : 0 #0...511 top address for area 1
Area 1 Size : 50 #0...512 area 1 data size in words (0=not used)
Area 2 Top : 0 #0...8191 top address for area 1
Area 2 Size : 100 #0...8192 area 2 data size in words (0=not used)
BP Area 1 Top : 50 #0...511 top address for area 1
BP Area 1 Size: 50 #0...512 area 1 data size in words (0=none transferred)
BP Area 2 Top : 100 #0...8191 top address for area 1
BP Area 2 Size: 100 #0...8192 area 2 data size in words (0=none transferred)
Important:
The module only generates the blocks required to transfer the data
you configured. For this example only one Area 1 block and one Area 2 blocks
are required, so only blocks 1 to 4 are used for data transfer. The larger the
areas, the more blocks are required to transfer data (and the more time is
required to update the whole block).
In this example, configure the FL/ET-T-V2 module with the values in the following
illustration:
