Table 23 - LED Error Code with Respective Fault/Alarm Source
➊ The Fault/Alarm code, available from a HIM or configuration software, provides more detailed information
concerning the source of the fault/alarm. Fault and alarm codes for the same event (e.g., Line Loss) are the
same.
Troubleshooting with
Monitoring Equipment
The SMC-50 controller has built-in detailed diagnostics fault codes and metering
functions. These fault codes and metering functions can be accessed through a
local 20-HIM-A6 or remote 20-HIM-C6S module or by using a Rockwell
Automation Drive Software package such as Connected Component
Workbench.
