8.4 Loading an application program on a
controller signed with digital signature
A c.pCO controller signed with a Digital Signature can be used only
with an application software signed with the same signature. In order to
generate an application signed with Digital SIgnature, it is necessary to
follow the procedure described in the previous paragraph and proceed
with the installation of the application as described in paragraph 6.6.
If the digital signature for the application program being loaded on the
c.pCO does not correspond to the digital signature on the controller,
when loading the application program by using c.factory tool, a screen
is displayed prompting for the password corresponding to the digital
signature currently loaded on the c.pCO.
If the password entered is correct, the program will be uploaded correctly.
Note:
if both a protection password and a digital signature have
been set on a c.pCO, the latter has priority.

menu;
