Wire break recognition
Via the Bits 0 and 3 of Byte 0, the wire break recognition is activated for the
input channels. The wire break recognition is only available for the current
measuring range of 4...20mA and at (thermo) resistance measuring. A wire
break is recognized when the current input during current measuring sinks
under 1.18mA res. when the resistance at (thermo) resistance measuring
reaches infinite. This causes an entry in the diagnosis area and is shown
via the SF-LED.
If a diagnostic alarm is activated, a diagnosis message is sent to the super-
ordinated system.
Diagnostic alarm
With the help of Bit 6 of Byte 0, you may release the diagnostic alarm. In
case of an error like e.g. wire break, the superordinated system receives
record 0 (4Byte). For an extended diagnosis you may then call record 1
(12Byte). More detailed information may be found below at "Diagnostic
data".
CPU-Stop reaction and replacement value
With Bit 4 and 5 of Byte 1 and Byte 12 ... 15 you may set the reaction of
the module at CPU-Stop for every output channel.
Via Byte 12 ... 15 you predefine a replacement value for the output channel
as soon as the CPU switches to Stop.
By setting Bit 4 res. 5, the last output value remains in the output at CPU-
Stop. A reset sets the replacement value.
Function-no.
Here you set the function-no. of your measuring res. output function for
every channel. Please see the according table next page.
