F –
File Transfer Utility – Software that supports transfer of an MVA
file between a computer that does not have MessageBuilder
running, and a MessageView terminal. It can also download the
RTC clock and upload the HE Stack file. In Microsoft Windows it
appears as an icon in the MessageBuilder group.
Firmware – Software that allows the MessageView terminal to run
an Application. Several versions of firmware are available,
depending on how the terminal is to be used. Firmware can be
upgraded using software disks from Allen-Bradley and the
MessageBuilder Download command.
Flashing – A Message or part of a message that is emphasized by
being turned on and off regularly on the MessageView terminal
display.
Function Keys – A set of keys labeled F1 to F16 (only on the
MessageView 421F terminal) that may be enabled for a Message.
When a displayed message has a function key or keys enabled, the
terminal operator can use the key(s) to initiate a procedure. Function
keys are disabled unless they are specifically enabled for a message
being displayed.
G –
Global – An Attribute or Parameter that is defined once, and may
then be used as often as needed in the application.
Graphic – One of 32 standard ISA Bitmaps representing motors,
valves and other objects used in manufacture.
Greyed – A command that is unavailable or disabled at the moment
is represented by a greyed icon, menu item or button. For instance,
most of the commands on the Format menu can be used only when
the cursor point is in the Edit Box. When it is elsewhere in
MessageBuilder, these commands are greyed out.
H –
Handshake – Acknowledgement that data has been received by
another device, such as a Logic Controller.
HE Stack – Acronym for the Historical Event Stack. A file in the
MessageView terminal in which messages are logged as they are
Triggered, with a time/date stamp. It may be viewed by the terminal
operator, or uploaded into a computer for analysis.
