Firmware Update
For upgrades and bugfixes it is possible with the help of STEP 7 HW Config (as of V 5.2) to
download firmware updates to the operating system memory of FM 350-1.
Note
Starting the firmware updates deletes the old FM 350-1 firmware.
If the firmware update is interrupted or terminated, the FM 350-1 will no longer be capable of
functioning.
In this case start the firmware update again and wait until it has been completed
successfully.
CiR
The FM 350-1 is CiR-compatible, i. e. via configuration modification at RUN of the CPU you
can change the FM 350-1 parameters. Parameter changes resets the FM 350-1 and is
essentially a reparameterization. /3/
The FM 350-1 allows parameter changes from the user program during operation.
Isochronous mode
The module supports isochronous mode.
