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 AFC 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 Multi-2 Unit
modular I/O board. For further technical information on the Interbus S interface go to the HMS website.
