11.10.9 Start value for the analog output
This parameter defines the specified value at which 0 or 4 mA is output. The value can be
greater or less than the end value.
11.10.10 End value for the analog output
This parameter defines the specified value at which 20 mA is output. The value can be
greater or less than the start value.
11.10.11 Output value following fault or SIMATIC STOP
The default settings set the analog output to the defined value following a module fault
(operating error) or upon SIMATIC CPU STOP.
If the analog output is, for example, to be set to 3.5 mA following a fault, this is defined with
this parameter. The current value to be output is entered.
System can be switched to unsafe state
If the analog output is to be set to a given value following a fault (operating error), you must
ensure that this poses no danger.
11.10.12 Trace recording cycle
The trace function is used for the continuous recording of measured values. The recording
rate is defined with the parameter.
11.10.13 Trace storage method
This parameter is used to specify the response of the trace memory.
