5.7 Memory and Storage
Computers can hold information in two ways. Information can be in
current memory
or in
storage
. Current memory (also known as RAM) is where the ProtoTRAK EMX holds the
operating system and any part program that is ready to run.
In contrast, storage is where the programs are saved until they are erased deliberately.
Programs are stored on the ProtoTRAK EMX on an internal flash drive that is capable of holding
hundreds of typical programs.
If power is lost or turned off, programs that are in current memory are lost, but programs stored
on the internal drive are not.
These programs can be transferred from the internal memory to an external thumb drive via
service codes 340 and 341.
Virus Protection:
As a device, ProtoTRAK CNCs are not generally susceptible to viral infections. The part
“programs” they run are non
-executable text files. You can further assure protection by avoiding
e-mail programs and web browser programs loaded onto the ProtoTRAK and by using a router
with a firewall. An anti-virus program is not necessary since the virus risk is low, and is not
recommended because the background tasks may cause damage by interfering with ProtoTRAK
real-time operation.
Microsoft Updates:
Please note that the ProtoTRAK control is not designed to be automatically downloading updates
from Microsoft, or for that matter any 3
rd
party software. There is only a limited amount of free
space on the compact flash card, and downloading files to it until it is full may result in the
ProtoTRAK to stop working properly.
Also note, that administrators must exclude the ProtoTRAK from programs such as Windows
Server Update Service, where the software will automatically try to download updates to the
control.
