4.4.2 Communication between engineering PC and 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.
– 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 .
– 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 at least achieved the Pre-
Operational state, this communication path comes second. We recommend to
commission the EtherCAT bus as soon as possible to be able to use the gateway
function.
