How to take backup in Honeywell TDC-3000 having only one nodepair of History module and several NIMs, HPMs? And what are the files to be taken as backup? Please tell the extension of the files for easy identifying. It will be very helpful to me if anybody help me in this regard.

 

use BACKUP PN:xx $Fn
where xx is the HM node number and n is the drive number.
Note: There are also some backup command files in the &EC folder of the &Z1 disk.
