12.5.5 Resetting of status bits
The reset of the status bits is initiated with a rising edge 0 → 1 at RES_STS (byte 1, bit 0) of the module’s
control interface
Process output/control interface.
Status bits:
STS_ZC, STS_UFLW, STS_OFLW
12.5.6 Error acknowledgment
Error messages as "overload at output" (DIA_DOx) or "parameterization error" (ERR_PARA) automati-
cally cause a diagnostic message.
They do not have to be acknowledged. The reset of the diagnosis is done automatically after the dele-
tion of the error.
The reset of a "ERR_PARA"-diagnostic message is done immediately after the deletion of the error, a
"DIA_DOx"-diagnostic message is reset with delay, depending on the severity of the overload.
