Real-time calendar – you can enter and display the date, and use the date
in a message. Date format is month/day/year — July 16, 1984 is
7/16/84.
Peripheral fault detection – module sets bit 027/06 in the processor data
table when the module detects a fault in the peripheral device
Module reconfiguration – you can reconfigure the module’s operational
configuration (internal switch settings) from the peripheral device
keyboard
Selectable communications configuration – you can select EIA
RS-232C communication (up to 50 feet) or A-B long line
communication (up to 5,000 feet) with the RG module
Selectable communication rates – allow you to increase the
communication rate to 19,200 bits
Selectable number of data bits – you can choose either seven or eight
data bits per character
Messages can be entered into memory from either the T3 industrial
terminal or a peripheral device connected to channel C of the industrial
terminal. If the industrial terminal is used, one of two keytop overlays can
be used, depending on whether graphic characters are desired (Figure 9.1):
Alphanumeric Keytop Overlay (Cat. No. 1770-KAA)
Alphanumeric/Graphics Keytop Overlay (Cat. No. 1770-KAB)
The messages can be manually displayed or printed on the T3 industrial
terminal or peripheral device by a key sequence each time a message
is desired. They can also be activated through program control by
programming specific data table bits in the ladder diagram program
(Section 9.3).
