Introduction to Fieldbus
Fieldbus is a generic term for communication between a GEM80 Controller and plant
input and output. The currently supported protocols are Profibus FMS/DP, CANopen
and DeviceNET. Master functionality is supported in each case.
The Fieldbus plug-in modules are peripherals of the GEMLAN-T compatible processor
module. Up to two modules in any combination are supported per controller. A power
converter module must also be fitted; this can power up to two Fieldbus modules
simultaneously.
Each Fieldbus module has a front panel to permit connection to the Fieldbus network
and to a diagnostic serial link. Ribbon cables connect the module and the panel. The
panel also has LED indicators, which mimic the Fieldbus module’s on-board indicators.
The GEM80-500 can support up to 5 plug-in modules; each Fieldbus module fitted
consumes one from this allowance.
