8.3.14 Cyclic register (bank 0)
Analog inputs
The input status is registered with a fixed offset with respect to the network cycle and istransferred in the same cycle.
Input filter
Filtering for all analog inputs is configured using this register. The minimum cycle time must be>500 µs.
If the input filter is active, then the channels are scanned in ms cycles. The time offset betweenthe channels is 200 µs. The conversion takes place asynchronously to the network cycle.

Input ramp limitation
Input ramp limitation is executed before filtering takes place.
The amount of the change in the input value is checked to make sure the specified limits are notexceeded. If the values are exceeded, the adjusted input value is equal to the old value ± thelimit value.
The input ramp limitation is very well suited for suppressing disturbances (spikes). The followingexamples show the function of the input ramp limitation based on an input jump and adisturbance.
Example 1: The input value makes a jump from 8,000 to 17,000. The diagram displays theadjusted input value for the following settings:
Input ramp limitation = 4 = $07FF = 2047
Filter level = 0

Filter level
The input value is evaluated according to the filter level. An input ramp limitation can then beapplied using this evaluation.
Formula for the evaluation of the input value:
The following examples show the function of the input ramp limitation based on an input jumpand a disturbance.
Example 1: The input value makes a jump from 8,000 to 16,000. The diagram displays theevaluated value with the following settings:

Example 2: A disturbance is imposed on the input value. The diagram shows the evaluatedvalue with the following settings:

Input status
A change in the monitoring status generates an error message. The input value has a lower limitof $0000. Underflow monitoring is therefore not necessary.

8.3.16 Function models
A function model describes the registers for the module (memory model) which are available forthe application. Only these registers are processed on the module during each cycle andcyclically transferred using the bus. The cycle time can be minimized by selecting the correctfunction model.
Minimum cycle time
The minimum cycle time is the minimum time needed for the bus cycle to be shut down withouta communication error or malfunction occurring. It should be noted that very fast cycles reducethe idle time needed for handling monitoring, diagnostics and acyclic commands.
Minimum I/O update time
The minimum I/O update time refers to the minimum time it takes for the bus cycle to shut down,so that in each cycle an I/O update takes place.
