NX-series EtherCAT Coupler Unit User’s Manual (W519)
• This object gives the Sysmac error status for the EtherCAT Slave Terminal.
• The assignments of bits in the Sysmac error status at subindex 01 hex are listed below. The applica-
ble bit is 0 (FALSE) if no error exists, or 1 (TRUE) if an error exists.
Bits 6 to 15: Reserved
Bit 5: Minor Fault
Bit 4: Observation
Bits 2 to 3: Reserved
Bit 1: Reserved
Bit 0: Reserved
Refer to Details of I/O Data in the EtherCAT Coupler Unit on page 9-16 for details on the Sysmac
error status.
• Subindex 02 hex is used to clear the Sysmac Error Status.
Write 01 hex to clear the Sysmac Error Status. If you write a value other than 01 hex, the command is
invalid and the abort code is returned.
When a read is performed, 00 hex is given.
• This object gives observation-level Controller events that are detected by the EtherCAT Slave Termi-
nal.
• Subindex 00 hex gives the number of observations that are detected by the EtherCAT Slave Termi-
nal.
