*) If you want to get 0A respectively 0V as output value at CPU-STOP, you have to set the replacement value E500h.
Parameter
n
Wire break recognition
–
The bits 0 ... 4 of byte 0 allow you to activate the wire break recognition for the
input channels.
–
The wire break recognition is only available for the current measuring range of
4...20mA and thermo resistance measurement.
–
A wire break is recognized, a diagnostic entry is made and displayed by the SF
LED when the current during current measuring (4 ... 20mA) sinks under 1.18mA
respectively at thermo resistance measurement the resistance becomes endless.
–
If additionally a diagnostic interrupt is activated, a diagnostic message is sent to
the superordinated system.
n
Diagnostic interrupt
–
The diagnostic interrupt is global released for the digital and analog part.
Chap. 6.10 ‘Counter - Parametrization’ page 114
In case of an error like e.g. wire break, the superordinated system receives record
set 0. For a channel specific diagnostic you may then call record set 1.
n
CPU-Stop reaction and substitute value
–
Via byte 14 ... 17 you predefine a substitute value for the output channel as soon
as the CPU switches to Stop.
–
By setting bit 5 respectively 6, the last output value remains in the output at CPU
Stop. A reset sets the replacement value.
n
Function no.
–
Here you set the function no. of your measuring respectively output function for
every channel. These can be found in the corresponding function no. assignment
from the table for the input respectively output area.
n
Measuring cycle
–
Here you may set the transducer velocity for every input channel. Please regard
that a higher transducer velocity causes a lower resolution because of the lower
integration time. The data transfer format remains unchanged. Only the lower bits
(LSBs) are not longer relevant for the analog value.
