A-8-4 Objects That Accept I/O Allocations
• Subindex 01 hex gives the Slave Terminal error status, Error Detection Flag, and I/O Refresh Flag.
• The assignments of bits for subindex 01 hex are listed below.
Bit 15: I/O Refresh Flag
Bit 14: Error Detection Flag
Bits 8 to 13: Reserved
Bit 7: Slave Terminal Major Fault
Bit 6: Slave Terminal Partial Fault
Bit 5: Slave Terminal Minor Fault
Bit 4: Slave Terminal Observation
Bits 0 to 3: Reserved
• Bits 4 to 7 are 0 (FALSE) if no error exists or 1 (TRUE) if an error exists.
• The Error Detection Flag in bit 14 is 1 (TRUE) if any of bits 4 to 7 are 1 (TRUE). Otherwise, it is 0
(FALSE).
• The I/O Refresh Flag in bit 15 is 1 (TRUE) if I/O communications are active for all of the NX Units in
the Slave Terminal. Otherwise, it is 0 (FALSE).
