Interface
InterBus S from Phoenix Contact is an open-ring based, distributed device I/O network. I/O data is
transmitted in frames that provide simultaneous and predictable updates to all devices in the
network. This interface board (S - version) has up to 512 bytes of assigned input data and 512 bytes
of assigned output data* (64bytes default). The 64 bytes of assigned I/O data allow a maximum of
512 inputs and 512 outputs per node. FEC I/O is assigned to the I/O points in these data areas
(some I/O will be designated spare). FEC Inputs match the discrete input layout. FEC Output
locations are programmed using the DSP User Console Software.
* When using Master boards where the PCP channel is NOT supported, the maximum number of
I/O will be 20 input bytes and 20 output bytes.
FEC integrates the Interbus S board manufactured by HMS Fieldbus Systems AB into the Main Unit
modular I/O board. For further technical information on the Interbus S interface go to the HMS
website. (www.hms.se)
