Error variable
Variable with the Error or Error Array data type.
When this variable has a value of "1", this
means that there is an error.

File Allocation Table
FATs are used to define filesystems.
Firewall
Firewalls are used to prevent outside attempts
to access IP addresses on a private network.
In other words, they are used to protect internal
data. When configured correctly, they can also
be used to set up rules or lists that prevent spe-
cific URLs from being requested, e.g., when
they are in violation of company policy. A fire-
wall's main task is to use the information in a
packet (the source and destination IP
addresses, as well as the port) to decide
whether the packet should be rejected or
allowed to pass. This also prevents packets not
meant for the network from subjecting the net-
work to an unnecessary load, as well as pack-
ets meant for the private network from
reaching the Internet.

GALILEO Project Inspector (GPI)
Program for testing GALILEO projects directly
on a PC. With a few exceptions, all of the HMI's
functions can be tested and tried out on a PC.
GALILEO Runtime System (GRS
The term "GRS PLC runtime system" refers to
the GRSW sequential programs on HMI
devices. These programs interpret (compile)
the data structure generated by the GALILEO
code generation program. GRS2 for Windows
CE devices with an x86 processor. The cor-
responding panel must have a parallel port and
a PCMCIA card. GRSW3 for all Windows CE
devices with ARM processors.
Gateway
Gateway When two computers on different net-
works want to communicate with each other,
the networks need to be connected with a
router. For example, surfing on the Internet
requires for packets to be routed from the Inter-
net to the network and vice versa. By using a
subnet mask, a computer can know whether
the receiver can be found on its network or
whether it is located outside of it. If it is located
outside the network, the computer will send a
packet to the router specified with the gateway
IP address.
