The SIMATIC 505–2556 features a configurable notch filter on the
analog–to–digital converters. This filter is very effective at removing
power–line frequency input noise from the analog–to–digital conversion
process. The filter frequency is configurable at jumper locatio CN10 on the
printed circuit board. With no jumper at CN10, the filter frequency is 60 Hz.
By placing the 3–pin jumper (included in an envelope packed with the
SIMATIC 505–2556) at location CN10, the filter frequency is changed to
50 Hz.
