Example) Change the moving average filter (address 40009) to 20 (0x0014) and digital
low pass filter to 6Hz (*).
* Select the F331 digital low pass filter setting from:
0: 3Hz, 1: 6Hz, 2: 12Hz.
Write "1" for 6Hz in the example.
Keep in mind that the relative address for writing in the moving average filter is 0x08.
11 (0x0B) Get comm event counter
The event counter is incremented by one each time each slave processes a request.
It is not incremented if there is an error in any frame or by reading other counters.
With the master, whether or not processing is executed can be judged by reading this counter before
and after the request.
As status, 0x0000 (slave is not busy) is always returned.
Example) Read the event counter.
The example shows the case of 264 (0x0108) commands having been processed so far in a not-
busy state (0x0000).
