Keyword removal
Dear Steve,
PLCs can be prevented from unauthorized reading/writing by using a keyword.
If you need the program & the parameters from the PLC, you should try to gather the key from the writer of the program.
If you do not need them, simply clear all program & parameter data from your PLC and download other ones to use it.
