B4 Changing Transmitter Settings with SIMATIC
To modify settings, you must first change the ‘Target Mode’ to ‘OOS’:
Figure 21 Changing Target Mode to ‘OOS’
Select OOS from the drop down and click the ‘Download to Device’
button to update the Target Mode. The ‘P’ indicator on the transmitter
will change to reverse to indicate ‘write mode’ is enabled. Click the
‘Upload to PG/PC’ button again to update the ‘Actual Mode’.
Note: Failing to ‘Upload’ after making changes may cause errors
‘Downloading’ to the device due to a mismatch between the
device and SIMATIC.
Now the user can change any transmitter settings by either typing in
new values or selecting options from a dropdown.
B5 Saving Changes to FLASH
When all changes are complete, click ‘Download to Device’, ‘Upload to
PG/PC’, then set ‘Target mode’ to ‘Auto’, and ‘Download’ again. The
reverse ‘P’ will change and the changes will be set in the meter.
When ‘Target Mode’ to ‘Auto’ is set, the transmitter validates all
changes made and will modify anything that is invalid back to its
previous value. If a value is invalid, the user may receive an error
from SIMATIC. Perform an ‘Upload to PG/PC’ to read back what is
currently set in the transmitter.
