BL20 - Communication in CANopen
D301087 0308 - BL20 CANopen4-226
In period duration measurement mode, the counter module
measures the time between two rising edges of the counter signal in
ms by counting the pulses of an exact internal quartz crystal refer-
ence frequency (1 MHz). An averaging operation can be carried out
over 1 to 1 000 periods. The number of periods is defined by the
Integration time parameter.
Write accesses initiate a parameter update on the BL20 internal
module bus.
The parameter is stored retentively in the gateway and is restored
with every node reset.
Note
The object 5820
hex
is only valid if the counter module is operating in
measurement mode.
