Resulting state
S + E
Solution
Use specific industrial pc, standard office PCs may have power saving options, graphic accelerateds and
other system services which disturb the real­time of the master.
CPU power may be too small for the PLC/NC program.
Increase EtherCAT and PLC/NC cycle time.
Use SyncUnits for the slaves using DCs.
