Occasionally there may be a need to edit the system.properties file on a NiagaraAX platform, which is located in its !/lib folder (niagaraRel/lib/system.properties# and are not processed. Comments “inactivate” many entries in this file—and typically these entries should remain inactive. To activate such an entry, you must delete the leading # character on that line of code.
Editing (and activating) system.properties entries is an operation for advanced users, with the possibility of undesirable results. Read all comment lines carefully,
and consult your support channel before making a change! Always save a backup copy of this file, and test after implementing
a change.
Note the system.properties file in a Workbench PC or Supervisor platform is similar to, but different from this same file on a remote JACE platform. You cannot directly edit a JACE’s system.properties file in place. Instead, you must copy it to your PC first (using the platform File Transfer Client) to edit.
A station must be restarted before changes to system.properties become effective. Thus, after copying (transferring back) an edited system.properties to any QNX-based JACE using the platform File Transfer Client, do the following:
-
the station using the platform Application Director. Wait for the station to stop completely, ensuring that it saves its database.
-
From the platform Platform Administration view, select . Allow sufficient time for the JACE to reboot and station to start.
-
Reconnect to the JACE’s station with Workbench to verify operation.
