Programming and system resources
Program creation and download in the PLC
ifm
downloader
The
ifm
downloader serves for easy transfer of the program code from the programming station to the
controller. As a matter of principle each application software can be copied to the controllers using the
ifm
downloader. Advantage: A programming system with CoDeSys licence is not required.
Safety-related application software MUST be copied to the controllers using the
ifm
downloader so as
not to falsify the checksum by which the software has been identified.
NOTE
The
ifm
downloader cannot be used for the following devices:
- PDM360: CR1050, CR1051, CR1060,
- PDM360 compact: CR1052, CR1053, CR1055, CR1056.
Certification and distribution of the safety-related software
Only safety-related application software must be certified before it is copied to the series machine and
used.
•
Saving the approved software
After completion of program development and approval of the entire system by the responsible
certification body (e.g. TÜV, BiA) the latest version of the application program loaded in the
controller using the
ifm
downloader has to be read from the controller and saved on a data carrier
using the name
name_of the_project file.H86
. Only this process ensures that the
application software and its checksums are stored.
•
Download of the approved software.
To equip all machines of a series production with an identical software only this file may be loaded
in the controllers using the
ifm
downloader.
•
An error in the data of this file is automatically recognised by the integrated checksum when
loaded again using the
ifm
downloader.
Changing the safety-relevant software after certification
Changes to the application software using the CoDeSys programming system automatically create a
new application file which may only be copied to the safety-related controllers after a new certification.
To do so, follow again the process described above!
Under the following conditions the new certification may not be necessary:
•
a new risk assessment was made for the change,
•
NO safety-related elements were changed, added or removed,
•
the change was correctly documented.
