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.
