Starting up the ClipX
68
a4643-1.0 HBM: public ClipX
The active parameter set is indicated by ACTIVE, and the start parameter
set by
BOOT.
You can save, load and activate parameter sets via the web browser or the
fieldbus interface, or activate them only via the digital inputs.
Processing parameter sets
On a new ClipX all the parameter sets contain the factory setting. You can reset
to those defaults at any time by clicking on
FACTORY SETTINGS in the
browser while a parameter set is active.
When the ClipX powers up, all the parameter sets are translated into the rele-
vant binary instructions and stored in the RAM in order to enable quick param-
eter set changing. Then the start parameter set is activated.
Each parameter set is assigned a check digit (CRC, cyclic redundancy check) in
the RAM in order to avoid errors.
It takes just a few milliseconds to change the active parameter set. However, in
the event of a parameter set switch which changes sensor settings, filters or the
analog output, the measured value status is set to
INVALID for approximately
2.5 seconds so as to suppress transient responses on the outputs. Brief time-
outs may also occur on the ClipX bus (SYS LED turns yellow).
on the second line in the panel indicates that the original settings of
the current parameter set are no longer being used. Save the settings to
a parameter set so as not to lose them.
