This bit switches on software simulation of the input values when it is set to "1". In this case, the
actual values are no longer used; the values set in object 3240
h
:04
h
for the respective input are
used instead.
•
h
:04
h
This bit specifies the value to be read in as the input value if the same bit was set in object
3240
h
:03
h
.
•
h
:05
h
This object contains the unmodified input value.
Computation of the inputs
Computation of the input using input 1 as an example:
The value of bit 0 of object 60FD
h
is interpreted by the firmware as a negative limitation switch, and the
result of the complete computation is stored in bit 16.
60FDh

special entries (reference and limit switches)

Input Routing
Principle
In order to deal with a more flexible input assignment there is a mode called "Input Routing Mode". This
mode assigns a signal from a source to a bit in the object 60FD
.
Signal source
Routing
Object 60FD
h
Activation
This mode is activated by setting the object 3240
:08
h
(Routing Enable) to "1".
Note
:01
h
to 3240:04
h
will have no function anymore until the output routing is switched
off again.
