5.14 FT, signal smoothing filter
This function block is available for easy800-SWD from device version 01 and
for easy800 standard devices from device version 04.
The function block smoothes noisy signals such as analog input signals. It
operates as a low pass filter. 32 signal smoothing filter function blocks are
provided.

Example of a smoothing filter
Figure 132:Wiring the function block coil
Parametric programming of the function block inputs/outputs
When using the function block in the circuit diagram for the first time, use
OK to automatically enter the general display of function block parameters,
as shown in the figure on the left. Enter the function block settings here.
The display contains the following elements:
→
If you are using the function block in time consuming
applications such as in conjunction with a DC PID controller, you
should not program any other time consuming applications on
this device, which may excessively lengthen the cycle time.
A trouble-free function block operation is only ensured if the
ratio of cycle time to scan time stated below is observed.
Divide the applications over two or several devices that you
interconnect via easyNet.
