NB: pay particular attention to the fact that it is absolutely not possible to assign the same
logic function to two different logic inputs: after changing the connection value that sets a
determined input, check that the value has been accepted, if not check that another has not
already been allocated to that input. In order to disable a logic input it’s necessary to assign
to it the logic function -1 : this is the only value that can be assigned to more than one inputs.
For example, to assign a specific logic function to logic input 1 you must first write the desired logic
number for connection I01 :
I01 = 14 Æ logic input 1 can be used to enable Fieldbus references
The logic functions that have been configured become active ( H ) when the input level is at high
status (20V < V < 28V), and there is a 2.2ms hardware filter. With the connection C79 it’s possible to
enable the active logic low state for a particular digital input, it’s necessary to sum 2 to the power of
ordinal input number:
For example to set digital inputs I0 and I3 to active low state, set:
922C79
30
=+=
The functions that have not been assigned assume default value ; for example, if the function
“external enable“ is not assigned it becomes, as default, “active ( H )” so the converter is as if there
were no assent from the field
3.1.4.1 INPUT LOGIC FUNCTIONS SET IN OTHER WAYS
In reality the input logic functions can also be set by serial connection and by fieldbus, with the
following logic:
o I00 Run : stands alone, it has to be confirmed by terminal board inputs, by the serial
and by the fieldbus, though in the case of the latter the default is active and
so, if unaltered, controls only the terminal board input.
o I01
÷ I31: is the parallel of the corresponding functions that can be set at the terminal
board, the serial or the fieldbus
