*) If you want to get 0A respectively 0V as output value at CPU-STOP, you have to set the replace-
ment 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 measure-
ment.
– A wire break is recognized, a diagnostic entry is made and dis-
played by the SF LED when the current during current meas-
uring (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.

Chapter 6.10 ‘Counter - Parametrization’ on page 152
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.
