EtherCAT slaves configuration is done carefully because some configurations must be carried out while the slaves are still in PREOP mode and some configurations are done when the slaves are in SAFEOP mode.
This function and its counterpart EC_USER_SAFEOP_CONFIG and EC_USER_OP_CONFIG are implemented in the library EC_USER.LIB. The purpose of these functions is to allow the user add his own code in order to conduct specific configuration to EtherCAT slaves.
EC USER PREOP CONFIG(slave address) is invoked while the slaves are still in PREOP mode.
