5.1.2 Functional description
The inputs
NEW_PRES_MULTI
and
NEW_PRES_SINGLE
are always read and
output to the
TR_Pres_Multi
and
TR_Pres_Single
outputs, irrespective of
the signal status of the other inputs. Once the preset block has been started via
the
REQ
input, the inputs
NEW_PRES_MULTI
and
NEW_PRES_SINGLE
may no
longer be changed.
The preset block is executed with the rising edge of the
REQ
input. The
VALID
and
ERROR
outputs
are
reset
to
0.
The
outputs
TR_IPAR_EN
,
TR_Pres_Request
and
BUSY
are set to 1.
The measuring system then executes the preset adjustment function. The time
for resetting the
REQ
input to 0 has no influence on the further execution of the
preset adjustment function.
When the preset adjustment function has been executed, the measuring system
sets the iParOK value of the measuring system F-IO data block and thus the
TR_IPAR_OK
input to 1. With setting of the
TR_IPAR_OK
input, the
TR_Pres_Error
input checks whether the preset adjustment function was
successfully executed. If the
TR_Pres_Error
input has the value 1, the
ERROR
output is set to 1. Otherwise the
VALID
output is set to 1. With setting of the
TR_IPAR_OK
input, the
TR_IPAR_EN
and
TR_Pres_Request
outputs are also
reset to 0.
When the
TR_IPAR_EN
output has been reset to 0, the measuring system resets
the iParOK value of the measuring system F-IO data block and thus the
TR_IPAR_OK
input to 0.
With resetting of the
TR_IPAR_OK
input, the
BUSY
output is reset to 0.
Execution of the preset block is complete.
