4.4.2 Communication between the Engineering PC and the field devices
For commissioning of the field devices, an online connection is required between the Engineering
PC and the corresponding field device. Depending on the state of the EtherCAT bus, there are two
options:
 EtherCAT bus not in operation ( 32)
 EtherCAT bus in operation (gateway function) ( 33)
4.4.2.1 EtherCAT bus not in operation
You can communicate serially or via CANopen.
Condition:
Serial communication:
• You require the E94AZCUS diagnostic adapter.
• The field device and Engineering PC (USB interface) must be connected via the diagnostic
adapter.
Communication via CANopen
• You required the EMF2177IB USB system bus adapter .
• The field devices and the Engineering PC are connected via the system bus adapter - either via a
point-to-point connection or via the bus system.
Advantage:
Quick option of communication without commissioning of the EtherCAT bus.
Disadvantage:
You require additional hardware.

Tip!
As soon as the fieldbus has been commissioned and is at least in the "Pre-Operational"
state, this communication channel is of secondary importance. We recommend that the
EtherCAT bus be commissioned as early as possible in order to enable use of the gateway
function.

Note!
For the i700 servo inverter, there is no possibility of communication in this case.
