EtherCAT:EC USER SAFEOP CONFIG
| Language: | English • 中文（简体） |
|---|
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 counterpart EC_USER_PREOP_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 perform specific configurations of EtherCAT slaves.
EC USER SAFEOP CONFIG(slave address) is invoked after EC_STARTMASTER has finished its work and all the slaves are in OP mode. It therefore starts by changing the slave's mode to SAFEOP, then performs the necessary configuration, and then raises the slave back to OP mode.
Input
Slave address
Output
None
Return Value
0 on success, -1 if failed. The user can change that.
