Communications Errors
■ Fault Codes
The DeviceNet Unit/Card has two kinds of fault codes: DeviceNet fault codes and DeviceNet Com-
munications Unit/Card fault codes.
• DeviceNet fault codes: Fault code outputs unified in DeviceNet
Class 29/Instance 01/Attribute 0D
• DeviceNet Communications Unit/Card fault codes: Fault codes for Inverter management
Class 2A/Instance 01/Attribute 70
Fault code stored in unit status bits 8 to 14 (Error flag in bit 15).
