I-Port
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 kbps.
–
SIO mode is not supported.
–
The maximum length of the process data is limited to 32 bytes of input data and 32 bytes of output
data.
–
Only one extract of the master commands is used.
–
“Plug&work” principle, configuration over IODD is not supported.
The connection type corresponds to a star topology. That means, only 1 device can be connected to
each I-port.
