Glossary
EPROM
Erasable programmable read-only memory. A PROM that can be
erased, usually with ultraviolet light, then re-programmed with
electrical signals. As with all PROMs, it is nonvolatile random-access
memory.
EEPROM (flash)
Electrically-erasable programmable read-only memory. A type of
PROM that can be erased and re-programmed by electrical signals. As
with all PROMs, it is nonvolatile random-access memory. Used by the
PanelView terminals to store applications.
firmware
Logic stored in read-only memory.
function keys
Set of keys (labeled F1-F10, F1-F16 or F1-21) on the PanelView
terminals used to initiate functions. The function keys are user-defined
and may have custom labels.
gateway address
A unique 32-bit address of the gateway connecting two individual IP
networks into a system of networks. When a node needs to
communicate with a node on another network, the gateway transfers
the data between the two networks. The IP address is formatted as
four sets of decimal numbers (0…255) with periods between them
(130.200.25.30).
interscan delay
Determines the amount of time the PanelView terminal waits before
re-reading the current screen data from the logic controller.
IP address
A unique 32-bit address of a node on the EtherNet/IP network.
keeper
The network controller of a ControlNet network.
