n The EtherNet/IP coupler can control maximally 64 system SLIO
modules.
n A system SLIO module can contain 1 ... 60byte I/O data.
n For the transport of this data stream, the data must be divided into
EtherNet/IP packages and encapsulated.
– Each package starts with the interrupt flags (1byte). With a
pending hardware interrupt respectively diagnostics interrupt
the according flag is set.
– Behind the interrupt flags there is the length ModLen located in
the data stream followed by the I/O data of the modules in
plugged sequence. Information concerning the allocation of
the I/O area of a module may be found in the description of the
corresponding System SLIO module.
From VIPA you may receive an EDS file (Electronic Data Sheet) for
your EtherNet/IP coupler. The file may be found in the service area at
www.vipa.com. Please install the EDS file in your configuration tool.
Details on the installation of the EDS file are available in the manual
supplied with your configuration tool.
Should there be unstable connections due to timeouts, so
you can make the following settings after installing the
EDS file:
à O change to 'point2point'
– Input T
– Output O
Example Rockwell:
– Assembly Instance 'Input' T
496byte
– Assembly Instance 'Output' O
496byte
– Assembly Instance 'Configuration' : 30decimal, Size:
400 byte
In the following you will find the description of accessing I/O area,
parameter data and diagnostics data of the System SLIO via
EtherNet/IP. Here 'I stream' is according to assembly class with
Instance-ID 0x0A and 'O stream' is according to assembly class with
Ä Chapter 4.8.2 'VIPA specific EtherNet/IP objects'
instance-ID 0x14.

You can start the communication with a Class1 connection. This
should be a point-to-point connection in both directions. Here the
frame size depends on the configured assembly class.
