6.2.6.1.1.2.1.2. Counting range (32bits)
Function - defines max. value assumed by the counter
Data type - number
Range - 0....2 147 483 647
Default value - 0
Comments - N/A
6.2.6.1.1.2.1.3. Triggering slope
Function - selects counting direction
Data type - selection list
Range - Bi 0->1
The change of counter state occurs upon signal change
from 0 > 1
Bi 1->0
The change of counter state occurs upon signal change
from 1 > 0
Bi 0->1 | 1->0
The change of counter state occurs upon any change of
signal
Default value - Bi 0->1
Comments - N/A
6.2.6.1.1.3. Filtering constant [s]
Function - Defines (in seconds) value of minimum duration of
altered state on input in order to consider state to be
stable.
Data type - number
Range - 0....163,83 [s]
Default value - 0,10 [s]
Comments - Setting value appropriate to contact characteristics
eliminates disturbance caused by contact bounce thus
preventing multiple registration of what is in reality one
pulse.
6.2.6.1.2. Outputs Q1 ... Q4
The MT-021 module is equipped in four relay outputs Q1...Q4. Outputs can operate in
one of two functional modes:
 monostable
 bistable
Each mode has a set of specific configuration parameters.
