I-port

1-8
The CTEL master module has 4 I-port interfaces. I-port is an
interface for the exchange of serial data for the connection of
decentralised function modules (devices) from Festo at field
level. It is based on the IO-Link technology and is compatible
with it in certain areas.
The limitations compared to the IO-Link standard are, among
others:
– Permanently set baud rate of 230.4 kBit/s.
– SIO mode is not supported.
– The maximum length of the process data is limited to
32 bytes input data and 32 bytes output data.
– Only one extract of the master commands is used.
– "Plug&work" principle, configuration over IODD is not
supported.
The kind of connection corresponds to a star topology. That
means, only 1 device can be connected to each I-port.
