In case the power supply will be controlled over serial Modbus interface
(with EtherCAT interface only for monitoring), the write register
“Ethercat_config” allows to disable the write actions coming from
EtherCAT. See Table 4-8.
Table 4-15 shows the command registers that must be set in order to
operate the power supply from EtherCAT.
