Key features
The IEM implements
One single software API supporting all implemented standards of industrial
Ethernet protocols
FPGA with NIOS II processor, covering all Ethernet communication proto-
col stack tasks (and thus reduction load on application processor to a min-
imum)
Supported protocols
o
EtherCAT
o
Ethernet/IP
o
POWERLINK
o
PROFINET
Pre-certification available (where applicable)
DPRAM interface guarantees data consistency
Optional SPI interface
On board LEDs
Galvanic isolated Ethernet interface
Certified components
Synthesis of all major design recommendations of the relevant industrial
Ethernet specifications
CE certified
