The product line Q.series-EC has been designed for demanding
measurements found in todays most industrial measuring and
testing environments. The range and flexibility of the modules
allows an optimized solution for each single task.
to optimize the data throughput
Data exchange with the automation level takes place via
EtherCAT interface.
Galvanic isolation
EtherCAT is a real-time Ethernet interface with an IEC-Standard
IEC61158 open protocol.
In measurement and automation technology it is suited for
accurate hard and soft real-time requirements. Short cycle times
(≤100 µs) and low Jitter for accurate synchronization (≤1 µs) are
features of the interface.

Oversampling (XFC technology)
EtherCAT also enables transmitting of very high data
rates at low bus cycle by over sampling.
In this case, a higher number of values of one channel
per PDO transmitted so as to reduce protocol
overhead.
Example: bus cycle 1 kHz, 100 times over sampling
=> 100 values are transferred per bus cycle
=> effective sample rate 100 kHz
