EtherCAT:EC USER PREOP CONFIG
Configuration of EtherCAT slaves must be performed carefully. Some configurations must be done while the slaves are still in PREOP mode, and some are done while the slaves are in SAFEOP mode.
This function and its counterparts 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 to add his own code in order to conduct specific configuration of EtherCAT slaves.
EC USER PREOP CONFIG(slave address) is invoked while the slaves are still in PREOP mode.
