GCI-SDO communication (TCP port 9410)
The TCP port 9410 serves to establish a parameter communication with the i700 servo inverter. The
PC (client) used for parameter setting and the i700 servo inverter (server) communication with each
other by exchanging data via the Ethernet telegrams which are fed into the cyclic EtherCAT
telegrams (see also
• The parameter data of the i700 servo inverter are stored in "objects". The objects serves, for
instance, to set operating parameters and motor data or query diagnostic information.
• The parameter data are transmitted as SDOs (Service Data Objects) and confirmed by the
receiver, i.e. the transmitter receives a feedback whether the transmission was successful.
• The transmission of the parameter data usually is not time-critical.
• The parameter communication enables the writing and reading access to the object directory of
the i700 servo inverter.
Note!
• Only one communication connection at a time is possible via the TCP port 9410, i.e.
only one client at a time can be connected to the i700 servo inverter.
• In case of a writing access to parameter data, make sure that the changes made are
not automatically saved in the i700 servo inverter.
The »EASY Starter« serves to upload the parameters of the i700 servo inverter and
save them as a file. This file can then be imported to the Engineering tool (e.g. »PLC
Designer«).
