Diagnostics Map Details - SMC Networks EXW1-BECAC Operation Manual

Diagnostics map details

When an error occurs in the Base or Remote, a flag will be set in a Bit corresponding to each item of
diagnostic information.
The errors for the system diagnostics 1 to 4 are for the entire system. Therefore, even if there is only one
unit which has an error in the constructed system, a flag will be set in a Bit corresponding to the error
content.
It is possible to identify the abnormal Remote using the Remote diagnostic information.
(It is necessary to set the "Diagnostic allocation" to "Advanced".)
Regardless of the setting of the "Diagnostic allocation", the abnormal module and unit can be identified
using the I/O Configurator provided by SMC.
