7.1.2.4 Input Routing
Principle
To perform the assignment of the inputs more flexibly, there is a mode called Input Routing Mode. This
assigns a signal of a source to a bit in object 60FD
h
.
Signal source
Routing
Object 60FD
h
Activation
This mode is activated by setting object 3240
h
:08
h
(Routing Enable) to 1.
Note
Entries 3240
h
:01
h
h
then have no function until Input Routing is again switched off.
Note
If Input Routing is switched on, the initial values of 3242
h
are changed and correspond to the function
of the input as it was before activation of Input Routing. The inputs of the controller behave the same
with activation of Input Routing. Therefore, you should not switch back and forth between the normal
mode and Input Routing.
Routing
Object 3242
h
determines which signal source is routed to which bit of 60FD
. Subindex 01
h
of 3242
h
determines bit 0, subindex 02
h
determines bit 1, and so forth. You can find the signal sources and their
numbers in the following lists.
