1*) “
SystemReady
”-Bit
•
“1”
If all “DataValid”-Bits of
all
configured sensors in the local configuration of the WDI100 are “1”.
•
“0”
If at least one on the “DataValid”-Bits of the configured sensors is “0”
2*) ”
ParameterWriteEnable
”-Bit
Set via the SET-Menu of the WDI100, item “CFG LOCAL / FB” to choose which configuration is used after
start-up:
•
“0”
the option is set to LOCAL, to indicate to the PLC that the parameters, that are downloaded to
the WDI100 at start-up will not be used.
-
The bit is also set to “0”, in case the WDI100 is in SET, DEL or CFG Mode, to indicate
the PLC that Parameters are blocked during this time. This function is to prevent local
changes to be overwritten by the PLC.
•
“1”
the option is set to FIELDBUS, to indicate, that the parameters sent by the PLC will be stored
at the WDI100 if they are valid.
3*) “
ParameterFault
”-Bit
•
“1”
to indicate the PLC a Parameter Error in case the Parameters are not stored because of the
“ParameterWriteEnable”-Bit or if a Parameter is out of range:
-
A range check of the parameter value is done for the Cell-ID (1-60) and for the last
configuration word (<=255) because this word is only half full.
-
The bit is also set to “1”, if there was a something wrong in the field bus telegram
(Package number or Parameter number does not match.
•
“0” if the parameters from the PLC are stored as local configuration.
