FMC masterFIP Board Functionality
FMC masterFIP is an interface card for the WorldFIP network in an LPC FMC form-factor.
WorldFIP is a deterministic rad-tol fieldbus used at CERN's LHC for a variety of control systems.
Cryogenics, Power Converters, Beam Instrumentation and other critical systems are using WorldFIP for
the exchange of data between their sensors and actuators and the control and supervision level. With
Alstom phasing out WorldFIP support in 2009, it was decided to insource this technology at CERN.
Figure 8: Bottom, top and front views of the masterFIP board
The FMC masterFIP mezzanine board is tested while mounted on a SPEC carrier board. The SPEC provides
FPGA logic, power supplies, memories, clocking resources and interface to the PCIe bus. The mezzanine
houses all the WorldFIP specific parts (FielDrive, FieldTR).
There are four different versions of masterFIP boards that correspond to the four different WorldFIP
speeds: 31.25 Kbps, 1 Mbps, 2.5 Mbps and 5 Mbps. One can visually distinguish the version by checking
the on the resistor indicators on the bottom side of the board as Figure 8 shows.
