Parameter Description
Execution Order for Block
This is the rack address of the PFQ
module.
Module address of the PFQ module.
Channel on selected Module.
High frequency value of the input
device. Exceeding this limit causes an
over-range error.
Low frequency value of the input
device. Exceeding this limit causes an
under -range error.
High range value. Frequency span in
Hz is scaled to the output range in
EU.
Low range value. Frequency span in
Hz is scaled to the output range in
EU.
Bias value added to the output.
The input signal is rejected if it is
below this pulse width. The frequency
of pulses above this width must be in
this frequency range; otherwise the
output goes to failsafe and a failure-
to-convert error occurs.
Filter time constant in seconds.
When FAIL is ON output is set to this
value.
When FAIL is ON output is set to
Upper Range Limit.
When FAIL is ON output is set to
Lower Range Limit.
When FAIL is ON output is held.
