Field Documentation

slaves_responding

unsigned int ec_master_link_state_t::slaves_responding

Sum of responding slaves on the given link.

Definition at line 296 of file ecrt.h.

al_states

unsigned int ec_master_link_state_t::al_states

Application-layer states of the slaves on the given link.

The states are coded in the lower 4 bits. If a bit is set, it means that at least one slave in the bus is in the corresponding state:

• Bit 0: INIT
• Bit 1: PREOP
• Bit 2: SAFEOP
• Bit 3: OP

unsigned int ec_master_link_state_t::link_up

true, if the given Ethernet link is up.
